Enhance Discord Bot Functionality in GO	~180 - 540 USD	1 hour ago	Client Rank - Medium Payment method verified 1 open job no reviews Registered: Oct 25, 2022 Canada 3
So currently we have a discord bot in GO and the three things I need help fixing are: 1. The queueing system Essentially the issue is rate limits so right now we have a working queue system (users enter, queue gets full, voice channels created, thread created and then players can start their game) But the issue is these are heavy on rate limits so we would like to have mini bots who are able to do this and move the functionality to them/have them retry so players are never stuck in a state. And on the backend it’s hooked up to a Postgres database where users who are registered their games get logged/scored and when games are created/finished or staff score the game they update. 2. Image generation/AI Reading There are a couple of commands that we would like to display with a photo background and adding some text above it. We have created ish this but we would like them to be nicer. This would also include adding some AI reading of images for scoring (since this is done with a in game /submit command) then a staff scores the game manually with buttons ideally we would want to have an AI score the game and then the ability for staff to hit buttons to easily rescore/correct the game. 3. We would like a table for rank permissions so we can assign certain commands to certain ranks. This would work by having a hierarchy which we set and any rank that has a higher level inherits the commands from earlier levels. Let me know what you think or any more information you might need.

Graph Database Expert Needed for Code & Property Graph Development	7 - 12 USD / hr	9 hours ago	Client Rank - Good Payment method verified $1 625 total spent 12 hires, 4 active 16 jobs posted 75% hire rate, 3 open job 4.96 of 7 reviews Registered: May 28, 2021 United States Leander 12:52 4
We are seeking a skilled developer with experience in creating Code Graphs and Property Graphs. The terms "Code Graph" and "Property Graph" relate to how information, particularly code, can be represented and analyzed using graph structures. Property Graph: A property graph is a general-purpose graph data model characterized by: Nodes (Vertices): Represent entities or data points. Each node can have properties, which are key-value pairs providing additional information about the node. Edges (Relationships): Represent connections or relationships between nodes. Edges are directed and can also have properties, describing the nature or attributes of the relationship. Labels/Types: Both nodes and edges can have labels or types, categorizing them and providing semantic meaning. This model is widely used in graph databases like Neo4j and JanusGraph, offering flexibility and expressiveness for storing and querying interconnected data. Code Property Graph (CPG): A Code Property Graph is a specific application of the property graph model designed for representing and analyzing source code. It merges several traditional program representations into a unified graph structure, including: Abstract Syntax Trees (ASTs): Represent the hierarchical structure of the code, showing how language constructs are nested. Control Flow Graphs (CFGs): Illustrate the possible execution paths through the code. Program Dependence Graphs (PDGs): Show data and control dependencies between different parts of the code. By combining these representations into a single property graph, the CPG allows for comprehensive code analysis, enabling tasks such as: Vulnerability detection: Identifying security flaws by tracing data flow and control flow paths. Code pattern recognition: Discovering recurring programming patterns or anti-patterns. Program understanding: Gaining a deeper insight into the structure and behavior of a codebase. The CPG leverages the power of property graphs to store and query complex code relationships, facilitating advanced static analysis and security analysis.

Muhammad has an incredible ability to quickly grasp the scope of the project and understand the end goals, which allowed him to work independently and efficiently. His ability to deliver high-quality work with minimal supervision is truly impressive. He proactively identified solutions, suggested improvements, and always stayed on top of deadlines. Communication was seamless, as Muhammad is responsive and ensures that all updates are clearly communicated throughout the entire process. He was open to feedback and implemented changes rapidly, which made collaboration smooth and productive.

When he is giving me unfamiliar task, I make it clear with him that I haven't done that before and I was not sure about it and he said it is okay please give your best, I tried with full potential to complete that tasks. Also, He is accepting my work until two weeks and after two weeks he just told me to refund his money as my code is not useful to him however I am sending daily update to him also push the code on git to review my work. If my work is not relating to what he want he should told me in some days only, it might not be problem for me and It's his mistake that he didn't discussed any technology stack and requirement properly while hiring he just said I only need to work on blade email template design and I was expert in it. Despite of his mistake, I was ready to give him a refund some amount by understanding that it might be some misunderstanding, but when I agree to give the refund he was asking for the more money that is not possible as it's his fault. Moreover, Upwork had also look at this problem and found it's clients mistake and Upwork concluded to not to refund client as it's his mistake. It was very bad experience working with Kris. I have never experience this type of client in my freelance journey and would not recommend to work with him.

To client: 1 I recently had the unfortunate experience of working with Kris Bob on Upwork. From the beginning, it was clear that he h… I recently had the unfortunate experience of working with Kris Bob on Upwork. From the beginning, it was clear that he had no intention of honouring the terms of our agreement. He initially presented a project as a "testing phase" with a limited budget, which I completed successfully and was commended for, with the hope that "real" work would come up once we are done with this. However, this was only the beginning of a pattern of dishonesty and manipulation. Despite agreeing to a specific hourly rate, Kris Bob continually underestimated the time required for complex tasks, suggesting they could be completed in an unrealistically short period. After investing significant time and effort into his tasks, I discovered that he has a history of hiring talent under false pretences, only to dispute their logged hours later. When I provided thorough documentation and evidence of the work completed, including expert assessments confirming the reasonable timeframes for the tasks, he still chose to dispute nine hours of my work. He exploited Upwork's policy that does not cover manually logged hours, fully aware that this would undermine my compensation. This review is a warning to other freelancers to avoid working with Kris Bob. His practices are deceptive, and he leverages loopholes in the platform to avoid paying fairly for the work done. I have compiled over 100 screenshots of his initial job posting, and our conversations on Upwork and Slack. They are in this Google Drive folder: https://drive.google.com/drive/folders/1fM1re7JhpXzYAiFw_WaQ1KEmEersy0V_?usp=drive_link If you want to see what he looks like, view his Facebook profile here: https://web.facebook.com/krisboblealiu/ Working with Kris Bob has been a deeply disappointing and unprofessional experience. Freelancers, be cautious and protect yourselves against such exploitative practices.

But the client asked me to do the first task with a very low fixed budget. When I asked why the budget was too low and he said that it was the expectable task and very simple. I was not sure if he is right but had to start the work. As I was working on this task I realized that this first task required too much effort and time. So I asked him to increase the fixed budget but he refused and even asked me to refund the time I had logged for my past work. I would tell everyone to never work with that guy.

What you’ll work on Designing and implementing Go microservices for: User, account, and challenge management Risk & rules engine (drawdown, daily loss, scaling logic) Payouts and financial workflows Admin panel APIs (monitoring, analytics, ticketing) Integrating with third-party trading platforms via REST/WebSocket, respecting rate limits and handling reconnects, retries, and backoff. Building data models on PostgreSQL (plus Redis-style caching) for high-throughput reads (leaderboards, dashboards, risk checks). Implementing event-driven pipelines (message queues / pub-sub) for trade ingestion, rule evaluation and notifications. Shipping production-grade code: tests, logging, metrics, and simple, observable behavior. Requirements Must-haves Strong experience with Go in production (not just hobby projects). Solid grasp of: Concurrency (goroutines, channels, context cancellation). Designing and consuming REST APIs; gRPC is a plus. Working with PostgreSQL (schema design, indexing, query optimization). Experience building or maintaining high-throughput or low-latency backends (fintech, trading, gaming, or similar is a plus). Comfortable with containers and modern DevOps workflows (Docker; any CI/CD system). Real, practical use of AI-assisted dev tools (e.g. Cursor, Claude Code, Copilot, etc.) — you know when to trust them and when to override them. Availability for at least 20 hours per week, overlap with EU time zones for collaboration. Clear written and spoken English. Nice-to-haves: Event-driven architectures (Kafka/NATS/etc.). WebSockets and streaming data. Risk/limits engines, payouts, or other financial systems. Prior work on prop-trading platforms, brokerage/back-office, or trading APIs.

The Challenge We're building Learning Time - an AI-powered child development app that will help Indonesian parents become their child's best teacher. The reality: 7 months to launch (Oct/Nov 2026 deadline) Bootstrap budget ($12.5K/month, 18-month runway) Market timing matters - we launch on time or lose momentum We will pivot - certainty is low, adaptability is required If you want stability and predictability, this isn't it. But if you want to build something that genuinely helps millions of parents, own the entire backend from day one, and ship a 0→1 product in 7 months - keep reading. What You'll Own You are the backend architect and engineer. Everything data, infrastructure, and APIs is yours. Your domain (70% of your time): Design and build the entire backend on Supabase (Postgres, Auth, Row-Level Security, Edge Functions, Realtime) Own data architecture, API design, and database optimization Implement authentication, authorization, and data privacy (Indonesia PDP Law compliance) Set up monitoring, logging, error tracking, and performance optimization Integration work (20% of your time): Connect backend to AI agent system (I own the agents, you own the plumbing) Build APIs for frontend consumption (React Native app) Integrate third-party services (payments, analytics, push notifications) Infrastructure & DevOps (10% of your time): Set up CI/CD pipeline (automated testing, deployment, rollbacks) Production infrastructure, staging environments, backup strategies Security hardening and cost monitoring You will NOT: Build AI agents (that's my job as CTO) Build the mobile UI (that's the Frontend Engineer's job) Do customer support or content creation What We Need Non-negotiables: 3.5+ years production backend experience - you've shipped real products to real users Supabase expertise or Postgres mastery - you know relational databases deeply (we can teach Supabase specifics if you're a Postgres expert) API design skills - you've built APIs that frontends actually love using Security-first mindset - data privacy isn't an afterthought for you Startup experience or mentality - you thrive in ambiguity and move fast Cursor or AI-assisted coding proficiency - you use Cursor, Windsurf, GitHub Copilot, or similar to code 3x faster Strong preferences: Experience with AI/ML product integrations (LangChain, vector databases, streaming APIs) Mobile backend experience (understanding mobile constraints like offline-first, battery, bandwidth) CI/CD and DevOps comfort (GitHub Actions, monitoring tools, infrastructure-as-code) Experience working remotely in distributed teams Culture fit (equally important as technical skills): Bias to action - you ship fast, iterate faster, don't wait for perfect Ownership mentality - you see a problem, you fix it (no "not my job") Comfortable with uncertainty - scope will change, we will pivot, you stay flexible Direct communication - you tell me what's broken, what's risky, what needs to change Mission-driven - you care about helping parents, not just collecting a paycheck What We're Building Product: AI-powered child development app for Indonesian parents (0-5 years old) Core features: Personalized milestone tracking and developmental insights AI-generated activity recommendations tailored to each child Multi-agent AI system (not a ChatGPT wrapper - custom agents for context, milestones, activities, etc.) Cultural relevance built for Asian parents (not Western parenting translated) Tech stack: Backend: Supabase (Postgres + Auth + Edge Functions + Realtime) Frontend: React Native (iOS + Android) AI: LangChain + Gemini 2.0 Flash/Pro (primary), Qwen (backup) Infrastructure: CI/CD pipeline, monitoring, automated testing Market: Indonesia first (200K Instagram followers = built-in distribution), then expand to Southeast Asia Business model: App drives eCommerce, eCommerce validates app (flywheel). Logistics Start date: February/March 2026 (flexible within that window) Timeline: 7-8 months to MVP launch (Oct/Nov 2026) Work setup: Fully remote from day one, can be on-site in Jakarta Overlap required: 3-4 hours/day with CTO (timezone TBD based on your location) Weekly sync: 1-hour technical planning session Async-first: Written updates, clear documentation, minimal meetings Compensation: Salary: Competitive for Southeast Asia market (specify your expectations in application) Team: Report to me (CTO) Work alongside Frontend Engineer (React Native) Collaborate with Design Agency (4-week contract for UI/UX) I own AI/ML, you own backend, Frontend Engineer owns mobile UI Include: Resume/CV (PDF) GitHub or portfolio (show me what you've built) Answer these 3 questions (3-5 sentences each): Why this role? What excites you about building this product for Indonesian parents? Your biggest backend challenge: Describe a hard technical problem you solved. What made it hard? How did you solve it? Startup readiness: Why are you willing to take the risk of joining a 7-month sprint to launch? Availability: When can you start? Any constraints on overlap hours? We'll review applications within 1 week and reach out if there's a fit. Final Note This role is not for everyone. Don't apply if: You need extensive onboarding and hand-holding You're risk-averse and need guaranteed outcomes You want to work on a small, well-defined piece of the system You're looking for work-life balance above all else right now DO apply if: You want to own the entire backend of a product from scratch You thrive under pressure and ship fast without sacrificing quality You believe AI can genuinely help parents raise confident, capable kids You're excited by the challenge of building in 7 months what most teams take 18+ months to ship We're not building another CRUD app. We're building something parents will genuinely love. If that excites you, let's talk.

When it was done, they asked for another similar error to be fixed as well, and it was okay as the contract is hourly based, not fixed price. So, I fixed both errors. After that the client asked me to try to fix one a bit more complex issue and I tried what I was able to do but as the client has a problem to give me proper access to the wp admin area I was not able to check the things from there and that slow down the progress as for 4 days the proper access to wp admin was not fixed/gaven.

The workflow is already running on Kubernetes, so the code has to build cleanly into Docker images and ship with the manifests (YAML or Helm) required for rolling updates, autoscaling, and basic observability (Prometheus metrics and structured logs). We can decide together whether Kafka, RabbitMQ, or another streaming layer makes the most sense; the services simply need a clean pub/sub abstraction so I can swap brokers later without code churn. Deliverables • Well-structured Go source for each microservice, including unit tests • Dockerfiles and CI script (GitHub Actions preferred) producing versioned images • Kubernetes deployment files (or Helm charts) with readiness/liveness probes • README that documents the event contracts and local-dev steps Code must be idiomatic Go, clear, and easy for my team to extend.

Job Description I am looking for an expert backend engineer to architect and build a proprietary, production-grade Real-Time Voice Calling Agent from the ground up. The Core Requirement: We are building a custom technology stack. We require a pure code-based solution using WebSockets and Async logic. Please Note: If your workflow relies on drag-and-drop automation tools (Make, Zapier, Flowise, etc.) or generic wrappers, this project is not for you. The Tech Stack and Features: Core Logic: Custom middleware (Python FastAPI/Twisted or Go/Rust) to manage full-duplex audio streams. Telephony: Twilio Streams / SignalWire. Turn-Taking: Strict sub-500ms VAD integration with instant "Barge-In" capability (handling interruptions immediately). Intelligence: RAG: Vector DB retrieval (Pinecone/Milvus) per turn. Multi-LLM Routing: Logic to route requests between models (e.g. GPT-4o vs Llama 3 via Groq) based on complexity. Audio Abstraction: Modular integration of multiple providers (Deepgram, ElevenLabs, Cartesia, Azure) with failover. Diarization: Accurate separation of User vs Agent audio for analytics. Required Deliverables: Latency under 800ms: End-to-end voice-to-voice response time. Interruption Handling: Flawless clearing of audio buffers when the user speaks over the agent. Cost Optimization: Architecture that minimizes token usage and allows provider switching to lower costs. Mandatory Application Requirements: To be considered, you must answer the following in your cover letter: Demo: Share a URL or video of a custom voice agent you have previously built. Costing: What was the Cost Per Minute (Telephony + AI Stack) you achieved in your previous build? Latency: What was your average end-to-end latency, and how did you optimize the "Time to First Byte" for audio? Stack: Briefly explain your approach to handling WebSocket concurrency and state management.
