Serverless Image Processing System on AWS (Terraform-Based)
Project Description
I designed and implemented a fully serverless, event-driven image processing pipeline on AWS, focused on scalability, cost efficiency, and production readiness. The solution automatically processes images as soon as they are uploaded, without any server management, making it ideal for modern web applications, SaaS platforms, and content-driven products.
The entire infrastructure is provisioned using Terraform (Infrastructure as Code), ensuring repeatable deployments, clean teardown, and industry-standard DevOps practices.
Business Problem Solved
Many applications require image optimization for:
- Faster website performance
- Reduced storage and bandwidth costs
- Support for modern image formats such as WebP
- Automatic thumbnail generation
Traditional solutions rely on persistent servers or manual processing, which increases operational overhead and cost.
This project solves the problem using a 100% serverless architecture that scales automatically and charges only for actual usage.
Solution Overview
When a user uploads an image to an S3 bucket:
1. An S3 event triggers an AWS Lambda function
2. The Lambda function processes the image in real time
3. Multiple optimized image variants are generated
4. The processed images are stored in a secure destination bucket
All resources including IAM roles, permissions, buckets, Lambda layers, and triggers are created and managed using Terraform.
Architecture Highlights
- Event-driven design with no polling and no idle resources
- Fully serverless with zero server management
- Auto-scaling to handle single uploads or traffic spikes
- Cost-optimized pay-as-you-use model
- Production-ready with security, observability, and maintainability
Key Features
Automated Image Processing
For every uploaded image, the system automatically generates:
- High-quality compressed JPEG
- Low-quality JPEG for bandwidth-constrained users
- WebP format for modern browsers
- PNG (lossless)
- Square thumbnail for previews
Infrastructure as Code using Terraform
- Repeatable deployments across environments
- Easy teardown with zero orphaned resources
- Clear separation of infrastructure and application logic
Lambda Layer Optimization
- Image processing library (Pillow) packaged as a Lambda Layer
- Built using Docker to match the AWS runtime
- Avoids native dependency and compatibility issues
Technologies Used
- AWS Lambda for stateless image processing
- Amazon S3 for secure object storage
- Terraform for infrastructure provisioning
- Python for image processing logic
- Pillow (PIL) for image manipulation
- AWS IAM for least-privilege security
- CloudWatch for logging and monitoring
Security and Best Practices
- Private S3 buckets with no public access
- Server-side encryption enabled
- Least-privilege IAM roles
- No hardcoded secrets or credentials
- Isolated Lambda execution environment
- Optional VPC support for enterprise use cases
- No always-running servers
- Free-tier friendly
- Typical monthly cost for low to medium traffic is approximately $0.50 to $2.00
Ideal for startups, MVPs, and scalable production workloads.
Use Cases
- SaaS platforms with user-generated images
- E-commerce product image optimization
- Media and content platforms
- Portfolio and CMS systems
- Mobile and web applications requiring thumbnails
Client Value
By implementing this solution, clients gain:
- Faster page load times
- Lower cloud infrastructure costs
- Zero infrastructure maintenance
- Modern, scalable cloud architecture
- A clean, DevOps-ready deployment model
My Role and Contribution
- Designed the complete serverless architecture
- Implemented image processing logic
- Built and optimized Lambda layers
- Provisioned all infrastructure using Terraform
- Applied security, scalability, and cost-optimization best practices
- Delivered a production-ready and reusable solution
Why This Matters for Clients
This project demonstrates my ability to:
- Build real-world AWS serverless systems
- Apply DevOps and Infrastructure as Code best practices
- Deliver scalable and maintainable cloud solutions
- Focus on business impact, not just code

I’m looking for a developer to help configure a Spring Boot application that uses DuckDB to ingest and query data from Parquet files stored in Amazon S3.
The goal is to create a working setup where a Spring Boot service can read Parquet files (from S3 or a local Parquet file for testing and this application) and load/query them through DuckDB reliably. This is mainly an integration/configuration task, with a focus on correctness, clarity, and reproducibility.
Scope includes:
Configuring DuckDB inside a Spring Boot application - in memory
Reading Parquet files from S3 - can be any file - make some data up
Supporting local Parquet file testing during development
Demonstrating ingestion and example queries - will only read data no updating
Clear setup instructions and documentation
Requirements:
Strong Java + Spring Boot experience
Familiarity with DuckDB or analytical databases
Experience working with S3 and Parquet files
Ability to test and validate the integration end-to-end

15 USD

I already have a fully-working JavaScript project that lives entirely on the front-end; users can select a file in the browser and the app handles everything client-side—there is no server-side code at all. What I now need is to put the site online under its own domain and make sure it stays available and secure.
I don’t have a hosting service chosen yet, so I’m looking for your recommendations on the best place to deploy a static site that still allows front-end file-upload functionality (e.g. Netlify, Vercel, Firebase Hosting, Amazon S3 + CloudFront, or any similar platform you trust). Once we decide on a provider, I’d like you to:
• Register or connect an appropriate domain name
• Deploy the current codebase (plain HTML/CSS/JS plus the existing upload logic)
• Configure HTTPS so visitors always see the secure padlock
• Hand over concise, step-by-step instructions for future updates
If extra configuration—such as enabling an SSL certificate, setting up a CDN layer, or adjusting CORS rules—is needed for the uploads to work flawlessly, please include that in your setup and note it in the hand-off notes.
The goal: after your work is done, I can visit my new domain, upload a file through the interface exactly as it works locally, and know that the site will stay online without me having to manage a server.

WordPress + Product Catalog + Data Integration Developer Needed(B2B Industrial / MRO Catalog, Feed-Driven, Quote-Based)Project Overview
West End Corporation is a U.S.-based industrial supply and MRO reseller. We are rebuilding and expanding westendcorporation.com into a scalable, feed-driven B2B product catalog that supports thousands of SKUs, daily supplier updates, blind-ship fulfillment, and RFQ-based selling.
This is not a brochure site.
We are looking for an experienced developer who can architect and implement:
A modern WordPress site
A scalable product catalog (WooCommerce or custom catalog)
Automated daily product feed ingestion (AWS S3 → database)
Quote-first workflow (Phase 1), with e-commerce enablement later
This project will evolve into a long-term platform, so we are seeking a senior developer or small agency, not a beginner.
Scope of Work
1. Website Revamp (WordPress)
Redesign and rebuild westendcorporation.com
Clean, professional B2B industrial aesthetic
Mobile responsive, fast-loading, SEO-ready
Clear positioning as an industrial / MRO supplier
Pages include:
Home
Capabilities / Industries Served
Product Catalog
Brands
Request a Quote
Contact
About
You may recommend theme or custom build, but site must be maintainable and scalable.
2. Product Catalog Architecture (Core Deliverable)
We will be ingesting daily product data feeds (TSV format) from a supplier hosted on Amazon S3.
You must:
Design database schema for products, pricing, availability, and shipping flags
Create WordPress custom post types and/or WooCommerce products
Build a catalog curation layer (admin can publish/unpublish SKUs)
Support thousands to tens of thousands of SKUs
Catalog Features
Category browsing
Faceted search and filters:
Brand

Price range
Availability
Blind-ship eligible
Product detail pages with specs, images, and SKU/MPN
SEO-friendly URLs and metadata
Schema.org structured data
3. Automated Supplier Feed Integration (Critical)
We receive daily product feeds via AWS S3.
You will:
Implement automated daily ingestion (cron job or scheduled task)
Pull latest feed files from S3
Parse TSV files
Normalize and upsert data into database
Track price changes, new SKUs, and availability updates
Produce basic sync logs or admin notifications
Manual uploads are acceptable only as a fallback — automation is expected.
4. Quote-Based Workflow (Phase 1)
Phase 1 will be RFQ-based, not full checkout.
You will implement:
“Add to Quote” cart (multi-SKU)
Quote submission form with:
Company info
Contact details
Quantities
Notes
Shipping ZIP
Admin dashboard to:
View submitted quotes
Export quote data
Respond manually (Phase 1)
5. Pricing Logic (Basic Rules Engine)
We need configurable pricing logic:
Cost-plus pricing
Category-based or brand-based markup
Ability to override price per SKU
Option to hide prices and force quote-only on select products
6. Admin & Curation Tools
Admin users must be able to:
Search imported SKUs
Publish / unpublish products
Override product names, descriptions, images
Assign categories
Flag “featured” products
Review daily sync summaries
7. SEO & Performance
Must include:
SEO-friendly structure
Product and category metadata templates
Clean canonical URLs
Fast load times (caching, lazy loading)
Indexable product pages (published SKUs only)
Technical Expectations
WordPress (PHP)
WooCommerce OR custom catalog solution (explain your choice)
MySQL / MariaDB

Core build: 4–6 weeks
Testing & refinements: 1–2 weeks
Total expected timeline: ~6–10 weeks
Budget
We are open to:
Fixed-price proposals with clear milestones, or
Time & materials with capped estimates
Please submit:
Your proposed cost range
Assumptions
What is included vs excluded
We are not seeking the cheapest bid. We are seeking the right technical partner.
How to Apply (IMPORTANT)
To be considered, your proposal must include:
A brief explanation of how you would architect:
Feed ingestion
Catalog storage
Quote workflow
Examples of similar work (B2B, catalog, or data-driven sites)
Your recommended approach (WooCommerce vs custom)
Estimated timeline
Estimated cost
Confirmation you can handle AWS S3 integration
Proposals without architecture explanation will not be reviewed.

Client Rank
- not enough data
-
Duration: 4 Weeks
Time Commitment: 4–6 hours total
Engagement Mode: Advisory + Screen Sharing (Consultation Access Only)
I am looking for an experienced AWS engineer to help me design, review, and fine-tune the setup of core AWS services, specifically EC2, S3, and RDS. The goal is to ensure that the environment is configured correctly from the start and follows AWS best practices for security, reliability, and performance.
This engagement is focused on guidance rather than direct implementation. I will provide consultation-only access, and the work will be done through live screen-sharing sessions, written instructions, and clear checklists that I can follow and apply myself in the AWS console.
In addition to initial setup and configuration, I want to establish a simple and effective maintenance and monitoring routine. This includes CloudWatch metrics, alerts, backup strategies, and operational checks that can be followed on a regular basis to keep the environment stable.
Finally, the project should produce a practical roadmap for future optimization and scaling. This should cover right-sizing, cost-efficient storage management, and scaling approaches that can be applied as usage grows, without over-engineering the solution.
Deliverables
• Architecture diagram covering EC2, S3, and RDS
• Step-by-step setup and configuration guide
• Maintenance and monitoring checklist with recommended CloudWatch metrics and alarms
• Backup and reliability guidance for EC2 and RDS
• Scaling and optimization playbook (Auto Scaling concepts, S3 lifecycle policies, RDS read replicas)
Skills: System Admin, Linux, Cloud Computing, Amazon Web Services, AWS Lambda, Cloud Security, Technical Documentation, DevOps, Amazon S3, System Administration

We have a frontend mockup live at https://dev.airprompter.com/. We’re looking for an experienced AWS serverless developer to finish the backend using AWS CDK.
Core requirements:
• Login / identity via Amazon Cognito
• User + app data in DynamoDB (optimized access patterns)
• API Gateway HTTP API endpoints wired to Lambda
• Permission guards inside Lambda (role/ownership checks)
• Efficient DynamoDB queries that minimize read/write costs while still supporting filters, sorts, and searches
• Strong preference for Local Secondary Indexes (LSI) over GSIs where feasible
You should review the current mockup to understand the intended UX and end goal.
⸻
What you’ll build / finish
1) Infrastructure as Code (AWS CDK)
• CDK app (TypeScript preferred; Python acceptable if already in repo)
• Environments/stacks for dev (and optionally staging/prod if applicable)
• Repeatable deploys + outputs (API URL, Cognito IDs, etc.)
2) Authentication & Authorization
• Cognito User Pool (and identity flow you recommend for a web app)
• JWT validation for API calls (HTTP API + authorizers)
• Clear user identity propagation to Lambda (claims, userId, roles)
• Authorization guards in Lambda:
• resource ownership checks (e.g., user can only mutate their own resources)
• role-based permissions (admin/mod/user if needed)
3) API Gateway HTTP API + Lambda endpoints
Design and implement endpoints that match the frontend needs (based on the mockup), typically including:
• Auth/session bootstrap (if needed)
• User profile/preferences endpoints
• CRUD endpoints for the app’s core objects (prompts, collections, etc.—final set based on the mockup and current codebase)
• Pagination, sorting, filtering, and search-friendly patterns
4) DynamoDB data modeling & performance
• Data model designed around explicit access patterns
• Query plans that avoid scans
• Optimize to reduce reads/writes:
• thoughtful partition/sort key design
• projections where useful
• conditional writes for idempotency
• batching where appropriate
• LSI-first preference: if you recommend any GSI(s), include a short justification tied to access patterns + cost.

My website is already feeding user-generated information into an Amazon Linux instance on EC2, but the data still sits there in an unstructured state. I need that user data organised so it can be stored, retrieved, and reliably backed up and restored without manual intervention.
The work involves:
• Designing a simple, logical directory or database structure that lives comfortably on my EC2 Amazon Linux environment.
• Implementing scripts or services to ingest new user records in real time (or near-real time), make them immediately retrievable, and schedule automated backups that can be restored with a single command.
• Documenting every step so I can understand how the solution fits into my current stack and maintain it after delivery.
You are free to leverage native AWS tools (for example the AWS CLI, CloudWatch, S3 lifecycle rules, or snapshots) so long as the final solution runs from EC2 on Amazon Linux and meets the store/retrieve plus backup/restore goals. Clean, well-commented code and clear documentation are the key acceptance criteria.

jan25 Developing and testing autoscaling python AWS RAG lambda and S3 React Chatbot
Summary
PROJECT TITLE: Build AWS Hosted RAG Chatbot Using LangChain, RDS PostgreSQL with pgvector, lambda Autoscaling, and React UI hosted on S3 AWS and AWS waf and getway api for requests as users access API interface
some help
https://github.com/ed-donner/production/tree/main/week2
https://github.com/AIbyKJ/RAG_chatbot
lambda based aws rag chatbot design : frontend with S3 React, for backend lambda with python code of chatbot using langchain. aws db rds aurora sql postgress for embeddings and chunks and conversation history. lambda is stateless. python packages upload to lambda through docker file (not zip ) since python packages size maybe big (docker created on EC2 and then save to s3. lambda reads docker from s3)
do not forget that test for autoscaling proves that there is no lost requests and that as more users as more aws resources allocated or vice versa as less users as less aws resources allocated
no one resource has public access like ec2 or db (for testing users has backend access using fastapi only through httpS (not http) request with password and or current session token ). All communications inside aws.
main ideas
• Python code and AWS deployment: Backend (FastAPI) and frontend (React) are deployed on AWS and are reachable from any desktop computer and any mobile.
• Core RAG works end-to-end: Users can upload documents, content is embedded into RDS PostgreSQL + pgvector, relevant chunks are retrieved, and answers are generated via OpenAI; chat history is stored and used for retrieval with an option to forget old history.
• Multi-user + security: Admin/user authentication works; role-based access control is enforced; private vs public documents are respected; sensitive resources (DB/S3) are not publicly exposed.
• Autoscaling validated: Load test proves scaling from 0 to 120 concurrent users within 10 seconds with no lost requests (for backend and UI where applicable).
• Reproducible educational deliverables: A step-by-step .doc with screenshots for each step plus an end-to-end video enables you to recreate the full system in your AWS account (AWS Console-first so all development from AWS browser but not from local computer , no terraform or .sh).
• Local Windows tooling: Python client + load-test scripts and instructions run from local Windows to test both backend and front end.
• Full cleanup guide: Clear steps to remove all AWS resources after deployment/testing are provided.
separate material to teach me how to use react for this task
python testing code and architecture to run many queries from my windows local computer to prove it can be done as many as 120 users using app on parallel with autoscaling . from 0 to 120 users and 120 to 0 users during 10 seconds
Details are :

do not forget to teach me how to remove all resources after deployment or stop

user can access both backend (fast api ) and frontend (React ) from local computer and mobile phone
I do not know REACT so you will create separate material to teach me how to use react for this task : create architecture , code , how to change if needed. Provide both instructional video and .doc file with screen copies and explanations , and react code and how to use vibe coding for such react task. How to test such ui automatically for autoscaling testing
important all deployment should be done from AWS console (no terraform or etc ) , rds access (review , add, change records ), etc. NO use of local computer for aws setups , use local comp only for browsing aws console
defend solution from hackers, like do not provide access to DB to everyone with URL, etc
Overview
I need an experienced developer who understands Python, LangChain, and AWS to build a complete RAG chatbot system. The system must support:
1 multiple users at the same time
2 autoscaling quickly
3 store vector embeddings in Amazon RDS PostgreSQL with pgvector
3 run a clean React user interface.
4 Use OpenAI as LLM, find openai model which can support such load (so many request per minute ) by using usual subscription (not special very expensive ) .
5 Data for RAG : 5 pdf files for each user (general format pdf file for example with pictures and tables , but only textual data should be used including content from tables ), each file has 3 pages (you provide these files). both user and admin can upload pdf files , some files for public use some files only for one user , privet. You provide such synthetic pdf files as many as needed. each user upload it own files
6 users conversation history saved on RDS to use RAG of answers recent history and most suitable historical chunks from previous conversation. Relevance of chunks calculated by taking to account chunks recency as well, add capability to forget too old conversation texts
7 deploy on S3 react and lambda backend .
Make sure when there is no chatbot use (no users using chatbot ) then there is no AWS resources use (no one VM running, then no need to pay to AWS ). When user start conversation when there is no conversation at all , then resources are allocated .
8 it should be the same deployment but supports both backend and frontend request from users from local computer . it needs to test autoscaling for both frontend plus backend and only backend : one for both frontend and backend and one for only backend .
This project includes backend development, database setup, React UI, AWS infrastructure, and load testing.
SYSTEM ARCHITECTURE REQUIREMENTS
Vector Database (Managed)
Use Amazon RDS PostgreSQL
Enable pgvector extension
Store embeddings, metadata, document chunks, users, and admin data
Must be fully managed by AWS (no set up from local comp)
stateless Python Backend (backend can be used not only by aws based React, but also from local windows computer python code, you provide this code to use backend from windows and instructions how to do it , for example needed python packages installation , etc )
Use LangChain for embeddings, text splitting, retrieval, and RAG logic
Backend must be completely stateless
No local file storage
All files go to RDS or S3
Safe for autoscaling LAMBDA instances
AWS Deployment
Use LAMBDA Auto Scaling
Minimum size 1
Maximum size 120 or more
Must be able to scale up within about 5 seconds from 1 to 120 users
Use S3 for file uploads
Set up all IAM roles, security groups, VPC networking, and private subnets
React Web UI
The user interface must include the following:
Admin Panel
Admin login with username and password
Admin dashboard
View users
Reset user passwords
Upload files to the knowledge base
View basic system information
User Panel
User login
Upload personal documents
Ask questions to the chatbot
See chat history
Access control by user role
UI should be clean, simple, and responsive.
RAG CHATBOT FUNCTIONS
Core functions
Upload PDF, DOCX, or TXT files
Automatically split, embed, and store in PostgreSQL
Perform similarity search using pgvector
Retrieve top results for each query
Combine retrieved context with the LLM for answers
Support many users at the same time
Authentication
Admin login
User login
Password hashing
Store all accounts in RDS
Scalability Requirements
Must handle a quick spike in traffic
Example: from one user to twenty users very fast several seconds
Stateless application nodes
Load balanced
Health checks and automatic recovery
LOAD TESTING AND SIMULATION
The project must include tools or scripts that simulate many users using RAG running on AWS from local windows
plain python load test code running on local windows
The simulation must:
provide framework and python code for running form my local windows . Test 120 or more users logging in and use app in parallel . load changing from 0 to high during given time range for example 10 seconds. prove all works correctly , no lost requests for both backed (python ) and frontend ( React )
Upload test files
Send many chatbot messages
Trigger autoscaling
Measure response times and performance
A short report must be included with the results.

HOW TO APPLY
Please include:
Your relevant experience
Any improvements you recommend for the architecture
4 days to do
make sure I can run firstly python code on my local windows by using aws cli for using aws resources like rds and s3 with line by line execution for debugging ( lambda python code runs locally, then I can use copy past to use this code in lambda ) and code exploration. And after I can run fully on AWS.
Important again : you provide .doc file with step by step instructions with screen copies for each step and video how to do end to end. I should be able to reproduce all on my account by myself by using your instructions
new user can register by himself only using provided unique password in advance
for example : I give to new user passwords abc123 then new user can register without admin by using this password , then user create new unique password to login afterward
for each event like registration , login or each chat entrance log is created and saved to S3
acceptance criteria I can run on my aws account and my local windows
I do not provide aws credentials or openai credentials , you use your own credentials for development. then I will use my own accounts for testing

His expertise was evident from the very beginning. He quickly understood the requirements, designed a clean and scalable Lambda architecture, and implemented the solution with great attention to detail.
Awais not only delivered efficient and well-structured code, but also ensured seamless integration with AWS services (S3, Lambda layers, API Gateway). He was proactive in suggesting best practices, communicated clearly, and always kept me updated on progress.
What impressed me most was his combination of deep technical skills and professional work ethic. He debugged issues quickly, optimized performance, and provided clear explanations so I could easily maintain and extend the system in the future.

I am seeking a seasoned AWS Solutions Architect or AWS Developer to immediately troubleshoot and fix a critical issue with an AWS Lambda function within a data-driven system. The function is not working as intended, and I need a quick diagnostic and resolution.
The Issue: We have a Lambda function integrated into a data pipeline that is failing or behaving inconsistently. You will be responsible for identifying whether the issue lies in:
• Code Logic: Runtime errors or unhandled exceptions.
• Permissions: IAM role/policy misconfigurations.
• Resource Limits: Timeout settings or memory exhaustion.
• Integration: Issues with triggers (S3, SQS, DynamoDB, API Gateway, etc.).
Project Scope:
• Review current Lambda configuration and CloudWatch logs.
• Identify the root cause of the failure.
• Implement a fix and verify successful data processing.
• Provide a brief summary of the resolution.
Requirements:
• Proven experience with AWS Lambda, CloudWatch, and IAM.
• Experience with data-driven architectures and event-driven triggers.
• Ability to work via provided IAM access.
• Immediate availability.

--------------
Frontend: Next.js (web) + React Native / Expo (mobile). Shared component library with Storybook.
Auth: Clerk for user and candidate auth; integrate role-based access control (RBAC).
Backend API: TypeScript + Node.js (NestJS or Fastify) or Python FastAPI. Microservices: ingestion, scraping/orchestration, RAG/LLM service, payments service, notifications/email, admin service.
Databases: PostgreSQL (primary relational), Redis (session & rate limits), Vector DB (Qdrant/Weaviate/Pinecone) for embeddings/memory, S3 storage for media.
LLM provider: start with Gemini (dev ease) or Anthropic; consider Llama 3.2 self-hosting in prod for control/cost. Use LangChain / Haystack for RAG orchestration.
Identity verification: Jumio / Onfido for ID + selfie + liveness.
Payments: Stripe Connect (destination charges or separate charges & transfers) — platform collects fees and routes donations to connected campaign accounts.

Project Context:
We are building a Smart Solar Inverter IoT system. We are moving from an early-stage prototype (self-hosted on EC2) to a scalable, production-grade cloud architecture. We need a hands-on engineer who can re-architect our data pipeline for reliability, security, and cost-efficiency.
Key Responsibilities
1. Architecture Migration: Lead the transition from manual EC2-based scripts to automated, cloud-native services (AWS Lambda, IoT Core, S3, Glue).
2. IoT Data Pipeline: Design robust ingestion pipelines for high-frequency sensor data using AWS IoT Core (MQTT). Ensure data is buffered and never lost during connectivity drops.
3. Database Management: Manage and optimize time-series databases. Specifically, experience managing PostgreSQL with TimescaleDB (on EC2 or managed services) and assessing trade-offs against Amazon Timestream.
4. Security & Access: Implement strict IAM roles, VPC security groups, and private subnets. (Stop the practice of opening ports for local access).
5. DevOps & Automation: Replace manual local server "fetch" scripts with automated cloud backups (AWS Backup/Data Lifecycle Manager) and CI/CD pipelines.
Required Skills (The "Must-Haves")
1. AWS Cloud & Architecture
- Core Services: Deep expertise in EC2, S3, IAM, VPC, and Lambda.
- Infrastructure as Code (IaC): Must know Terraform or AWS CDK. Note: This is crucial to prevent engineers from manually "clicking around" and creating unrepeatable setups.
- Serverless: Experience writing event-driven code (e.g., triggering a database write when a file lands in S3).
2. IoT Domain Knowledge
- Protocols: Deep understanding of MQTT and HTTPs.
- AWS IoT: Experience with Device Shadows, IoT Rules Engine, and Greengrass.
- Edge Cases: Knowledge of how to handle device offline states, message buffering, and retries.
3. Data & Database
- Time-Series Data: Specific experience with TimescaleDB (managing extensions, retention policies, compression) OR Amazon Timestream.
- PostgreSQL: Strong SQL skills and performance tuning.
- Storage Strategies: Understanding of "Hot" vs. "Cold" storage (e.g., moving old logs from DB to S3 Glacier).
4. General Engineering
- Backend: Python (Boto3) or Node.js.
- System Admin: Linux command line expertise (for managing the EC2 DB instance properly).
Client's questions:
We have a Postgres/TimescaleDB database running on an EC2 instance. We need to back it up daily and make the data available for the analytics team. How would you design this workflow? Give examples from your past projects to justify

We are seeking an AWS expert to assist us with critical issues in our account. Last year, a developer we hired to build a chatbot installed a set of tools on our account that have since malfunctioned and is now directing huge quantities of traffic towards our site. We haven't been able to fix the problem and as a result, these tools are effectively generating the equivalent of a DDoS attack against our site that is slowing down our site and costing us a lot of money.
We have tried to resolve the situation with AWS to no effect.
Therefore, we are looking for someone who can help us download our "good" files from AWS so we can close down our account that is malfunctioning due to the "bad" files.

jan23 Developing and testing autoscaling python AWS RAG lambda and S3 React Chatbot
Summary
PROJECT TITLE: Build AWS Hosted RAG Chatbot Using LangChain, RDS PostgreSQL with pgvector, lambda Autoscaling, and React UI hosted on S3 AWS and AWS waf and getway api for requests as users access API interface
some help
https://github.com/ed-donner/production/tree/main/week2
https://github.com/AIbyKJ/RAG_chatbot
lambda based aws rag chatbot design : frontend with S3 React, for backend lambda with python code of chatbot using langchain. aws db rds aurora sql postgress for embeddings and chunks and conversation history. lambda is stateless. python packages upload to lambda through docker file (not zip ) since python packages size maybe big (docker created on EC2 and then save to s3. lambda reads docker from s3)
do not forget that test for autoscaling proves that there is no lost requests and that as more users as more aws resources allocated or vice versa as less users as less aws resources allocated
no one resource has public access like ec2 or db (for testing users has backend access using fastapi only through httpS (not http) request with password and or current session token ). All communications inside aws.
main ideas
• Python code and AWS deployment: Backend (FastAPI) and frontend (React) are deployed on AWS and are reachable from any desktop computer and any mobile.
• Core RAG works end-to-end: Users can upload documents, content is embedded into RDS PostgreSQL + pgvector, relevant chunks are retrieved, and answers are generated via OpenAI; chat history is stored and used for retrieval with an option to forget old history.
• Multi-user + security: Admin/user authentication works; role-based access control is enforced; private vs public documents are respected; sensitive resources (DB/S3) are not publicly exposed.
• Autoscaling validated: Load test proves scaling from 0 to 120 concurrent users within 10 seconds with no lost requests (for backend and UI where applicable).
• Reproducible educational deliverables: A step-by-step .doc with screenshots for each step plus an end-to-end video enables you to recreate the full system in your AWS account (AWS Console-first so all development from AWS browser but not from local computer , no terraform or .sh).
• Local Windows tooling: Python client + load-test scripts and instructions run from local Windows to test both backend and front end.
• Full cleanup guide: Clear steps to remove all AWS resources after deployment/testing are provided.
separate material to teach me how to use react for this task
python testing code and architecture to run many queries from my windows local computer to prove it can be done as many as 120 users using app on parallel with autoscaling . from 0 to 120 users and 120 to 0 users during 10 seconds
Details are :
important
do not forget to teach me how to remove all resources after deployment or stop
important
user can access both backend (fast api ) and frontend (React ) from local computer and mobile phone
I do not know REACT so you will create separate material to teach me how to use react for this task : create architecture , code , how to change if needed. Provide both instructional video and .doc file with screen copies and explanations , and react code and how to use vibe coding for such react task. How to test such ui automatically for autoscaling testing
important all deployment should be done from AWS console (no terraform or etc ) , rds access (review , add, change records ), etc. NO use of local computer for aws setups , use local comp only for browsing aws console
defend solution from hackers, like do not provide access to DB to everyone with URL, etc
Overview
I need an experienced developer who understands Python, LangChain, and AWS to build a complete RAG chatbot system. The system must support:
1 multiple users at the same time
2 autoscaling quickly
3 store vector embeddings in Amazon RDS PostgreSQL with pgvector
3 run a clean React user interface.
4 Use OpenAI as LLM, find openai model which can support such load (so many request per minute ) by using usual subscription (not special very expensive ) .
5 Data for RAG : 5 pdf files for each user (general format pdf file for example with pictures and tables , but only textual data should be used including content from tables ), each file has 3 pages (you provide these files). both user and admin can upload pdf files , some files for public use some files only for one user , privet. You provide such synthetic pdf files as many as needed. each user upload it own files
6 users conversation history saved on RDS to use RAG of answers recent history and most suitable historical chunks from previous conversation. Relevance of chunks calculated by taking to account chunks recency as well, add capability to forget too old conversation texts
7 deploy on S3 react and lambda backend .
Make sure when there is no chatbot use (no users using chatbot ) then there is no AWS resources use (no one VM running, then no need to pay to AWS ). When user start conversation when there is no conversation at all , then resources are allocated .
8 it should be the same deployment but supports both backend and frontend request from users from local computer . it needs to test autoscaling for both frontend plus backend and only backend : one for both frontend and backend and one for only backend .
This project includes backend development, database setup, React UI, AWS infrastructure, and load testing.
SYSTEM ARCHITECTURE REQUIREMENTS
Vector Database (Managed)
Use Amazon RDS PostgreSQL
Enable pgvector extension
Store embeddings, metadata, document chunks, users, and admin data
Must be fully managed by AWS (no set up from local comp)
stateless Python Backend (backend can be used not only by aws based React, but also from local windows computer python code, you provide this code to use backend from windows and instructions how to do it , for example needed python packages installation , etc )
Use LangChain for embeddings, text splitting, retrieval, and RAG logic
Backend must be completely stateless
No local file storage
All files go to RDS or S3
Safe for autoscaling LAMBDA instances
AWS Deployment
Use LAMBDA Auto Scaling
Minimum size 1
Maximum size 120 or more
Must be able to scale up within about 5 seconds from 1 to 120 users
Use S3 for file uploads
Set up all IAM roles, security groups, VPC networking, and private subnets
React Web UI
The user interface must include the following:
Admin Panel
Admin login with username and password
Admin dashboard
View users
Reset user passwords
Upload files to the knowledge base
View basic system information
User Panel
User login
Upload personal documents
Ask questions to the chatbot
See chat history
Access control by user role
UI should be clean, simple, and responsive.
RAG CHATBOT FUNCTIONS
Core functions
Upload PDF, DOCX, or TXT files
Automatically split, embed, and store in PostgreSQL
Perform similarity search using pgvector
Retrieve top results for each query
Combine retrieved context with the LLM for answers
Support many users at the same time
Authentication
Admin login
User login
Password hashing
Store all accounts in RDS
Scalability Requirements
Must handle a quick spike in traffic
Example: from one user to twenty users very fast several seconds
Stateless application nodes
Load balanced
Health checks and automatic recovery
LOAD TESTING AND SIMULATION
The project must include tools or scripts that simulate many users using RAG running on AWS from local windows
plain python load test code running on local windows
The simulation must:
provide framework and python code for running form my local windows . Test 120 or more users logging in and use app in parallel . load changing from 0 to high during given time range for example 10 seconds. prove all works correctly , no lost requests for both backed (python ) and frontend ( React )
Upload test files
Send many chatbot messages
Trigger autoscaling
Measure response times and performance
A short report must be included with the results.

HOW TO APPLY
Please include:
Your relevant experience
Any improvements you recommend for the architecture
4 days to do
make sure I can run firstly python code on my local windows by using aws cli for using aws resources like rds and s3 with line by line execution for debugging ( lambda python code runs locally, then I can use copy past to use this code in lambda ) and code exploration. And after I can run fully on AWS.
Important again : you provide .doc file with step by step instructions with screen copies for each step and video how to do end to end. I should be able to reproduce all on my account by myself by using your instructions
new user can register by himself only using provided unique password in advance
for example : I give to new user passwords abc123 then new user can register without admin by using this password , then user create new unique password to login afterward
for each event like registration , login or each chat entrance log is created and saved to S3
acceptance criteria I can run on my aws account and my local windows
I do not provide aws credentials or openai credentials , you use your own credentials for development. then I will use my own accounts for testing

His expertise was evident from the very beginning. He quickly understood the requirements, designed a clean and scalable Lambda architecture, and implemented the solution with great attention to detail.
Awais not only delivered efficient and well-structured code, but also ensured seamless integration with AWS services (S3, Lambda layers, API Gateway). He was proactive in suggesting best practices, communicated clearly, and always kept me updated on progress.
What impressed me most was his combination of deep technical skills and professional work ethic. He debugged issues quickly, optimized performance, and provided clear explanations so I could easily maintain and extend the system in the future.
