Find React Projects on Upwork with Vollna

I’m putting together a short narrative scene and I want the visual language to lean equally on 2D grease-pencil work and true 3D geometry. Think of the camera drifting through a fully modelled set while hand-drawn characters and effects live right inside that same space—everything, including the camera itself, needs to move cohesively.

You would handle the entire animation pass: blocking, rough grease-pencil sketches, spline or stepped keys for the 3D objects, then clean-up, colour, lighting and final compositing inside Blender. Characters, props and even background elements should react naturally to one another, so timing and spatial accuracy are critical.

I’ll bring the script, reference boards and any voice or sound that’s already locked; you bring the scene to life. When we’re done I need both the rendered clip and the organised .blend file so I can revisit layers or adjust edits later.

Deliverables
• Final rendered scene (ProRes or lossless PNG sequence)
• Clean, labelled .blend project with grease-pencil layers, 3D rigs and camera moves intact
• Brief turntable or playblast showing each major layer for quick review

If full integration of grease-pencil and 3D animation inside one environment is your comfort zone, let’s talk.

About Akerio. Akerio is a UK-based applied AI company. We build platforms that turn messy enterprise data into scored, auditable recommendations: the next diesel price for one of Europe's largest independent fuel distributors, a risk flag on a tenant across 41 shopping centres, a credit score a bank's committee can trace back to the source record. Our models are built by a PhD team from Stanford and the University of Chicago, every output shows what drove it and how confident it is, and the platform runs on-premise or in the cloud. We are live in production across energy, commercial real estate and financial services, with 18 AI modules running in one deployment alone. We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used.
• Job: Full time
• Job type: Remote
• Salary: xxx
The role
A mall asset manager opens our platform before the monthly review to see which tenants are slipping, how footfall compares to forecast, and where costs ran over. If a widget is slow, a filter resets, or a chart axis misleads, they go back to Excel. Your job is to make sure they don't. You build the React screens across 49 dashboard widgets and the AI assistant that explains them, working from Figma designs and real user feedback that lands in Jira every week.
What you will work on
• Dashboard widgets for leasing, finance, budget and visitor analytics: time-series charts, forecast versus actual, week and month pickers, export to Excel.
• The customizable home dashboard: add, drag, resize and remove widgets with React Grid Layout, with widget filters kept in the URL and in Zustand.
• AI features: chat, quick summaries and per-widget AI commentary built with AI Elements, isolated cleanly from our MUI and Tailwind styles.
• Full Turkish and English support, including number, currency and date formats.
• Turning Figma designs into reusable components, and pushing back when a design breaks on real data.
• Code health: consistent ESLint and Prettier rules, dependency upgrades, and a frontend test setup we are building now.
Our stack
Area What we use
Core React, TypeScript, Vite, React Router
UI MUI, Tailwind CSS, shadcn/ui, AI Elements
State and data Zustand, axios, REST APIs from NestJS services
Charts and layout ApexCharts, React Grid Layout
Quality ESLint, Prettier, Trivy dependency scans; component and end-to-end tests being added
How we build Figma, Jira, Bitbucket, spec-first work with AI coding tools (Claude Code), code review on every PR
Your first six months
• First month: first pull request merged in week one, then one widget shipped to production.
• Month three: you own a product area (for example visitor analytics) including its components and its tests.
• Month six: you lead UI decisions for a new module, from Figma review to release.
What you bring
Junior (0 to 2 years):
• Solid JavaScript and TypeScript, and React you have used on something real.
• HTML and CSS done properly: semantic markup, responsive layouts, basic accessibility.
• A portfolio, a GitHub profile or a live project we can click through.
Mid (2 to 4 years):
• Production React and TypeScript, ideally with MUI or a similar component library.
• You have built data-heavy screens: charts, big tables, filters, and you know how to keep them fast.
• State management that scales past one page (Zustand, Redux or similar) and URL-driven state.
• You write component and end-to-end tests without being asked.
Both levels: clear written English, care for the person using the screen, and comfort with AI coding tools while still understanding every line you ship. Turkish is a plus.
Nice to have
• Experience with dashboards or B2B tools in real estate, retail or finance.
• UIs on top of LLM output: streaming, citations, tool results.
• Internationalisation beyond translated strings.
• Basic Node.js, enough to read the NestJS endpoint you call.
How we work
You hear the user's problem before you see the ticket. We write the spec first, review every pull request, and demo to clients often, so you will see your screens in use.
Hiring process
7. 30-minute intro call.
8. 30-minute session: present your case to the CPO and an engineer.
9. 15-minute call with a founder.
What we offer
• Fully remote, with overlap on UK and Türkiye working hours.

We are a small team shipping to demanding enterprise clients, so the work you do reaches production and gets used.

• Job: Full time
• Job type: Remote

The role
Our largest deployment, a retail property analytics platform, is live across 41 shopping centres. Asset managers, leasing and finance teams open it to see footfall, turnover forecasts, tenant risk and NOI, then ask the built-in AI assistant why a number moved. Behind it sit 49 dashboard widgets, 53 AI tools, a set of NestJS microservices and a Python compute service. You take features across that whole path: the React screen, the NestJS endpoint, the Postgres query, and the AI commentary that explains the result. You will also talk to the people using it, because most of our backlog comes straight from their feedback.

What you will work on
• Dashboard widgets for leasing, finance and visitor analytics: time-series charts, forecast versus actual, filters that live in the URL so a view can be shared.
• The customizable home dashboard: drag, resize and save widget layouts per user.
• NestJS microservices: core business APIs, notifications, and the AI service that runs LLM tool calls and talks to our tools over MCP.
• Data endpoints over PostgreSQL and PostGIS, with SQL migrations you write and own.
• Wiring Python forecasting and risk models (FastAPI compute service, scheduled by Airflow) into the product.
• AI features in the UI: chat, quick summaries and per-widget AI commentary, cached in Redis and generated in the user's language.
• Production quality: health checks, logging, dependency upgrades, and closing security findings before they become incidents.

Our stack

Frontend: React, TypeScript, Vite, MUI, Tailwind, shadcn/ui, Zustand, React Router, ApexCharts, React Grid Layout, i18n (Turkish and English)

Backend: Node.js, NestJS microservices in a Yarn workspace monorepo, gRPC, Kafka, Redis, OpenSearch, Socket.IO

Data: PostgreSQL 17 with PostGIS, SQL migrations
Compute and ML Python, FastAPI, Airflow for scheduled forecast and scoring runs

AI: Anthropic Claude via API, tool calling and MCP, RAG over client data, Langfuse for monitoring conversations and quality

Infra: Azure, Docker and Docker Compose, nginx, Jenkins, Bitbucket, OpenTelemetry and Jaeger, Trivy; Kubernetes (Rancher) on the roadmap

How we build: Jira, Figma, spec-first work with AI coding tools (Claude Code), code review on every PR
You need to be strong in TypeScript on both sides. The rest you can pick up here.

Your first six months
• First month: local setup running, first pull request merged in week one, one widget or endpoint shipped to production.
• Month three: you own one product area end to end (for example finance analytics) from Figma to production.
• Month six: you shape API and frontend standards across services and pair with juniors on their first features.

What you bring
• 4+ years building production web applications, with real depth in TypeScript, React and Node.js.
• NestJS or a similar structured Node framework, REST API design, and PostgreSQL schema and query work.
• You have shipped data-heavy UIs: charts, big tables, filters, exports, and you know how to keep them fast.
• Docker, CI pipelines and debugging in a deployed environment, not only on localhost.
• You write tests and care about code that the next person can read.
• Clear written English. Turkish is a plus: most of our current users work in Turkish.
Nice to have
• Python and FastAPI, enough to read and extend a compute endpoint.
• Microservice plumbing: Kafka, gRPC, Redis caching, tracing.
• You have built a UI on top of LLM output: streaming, citations, tool calls, human review.
• Experience with real estate, retail, energy or finance products.

How we work
Small team, short feedback loops. Client feedback lands in Jira every week, we write the spec before the code, and every pull request gets a review. We use AI coding tools as standard and still expect you to own every line you merge.

Hiring process
1. 30-minute intro call.
2. 30-minute session: present your case to the CPO and an engineer.
3. 15-minute call with a founder.

I need a web-based text-to-speech platform focused on one clear goal: letting users generate polished voiceovers for their videos, ads and social posts. The user flow should feel effortless. Visitors either paste their script into a text field or upload it as a document, pick the voice and language they like, fine-tune speed and pitch, choose their preferred output quality/format, then download the finished audio in seconds.

The site has to run smoothly on all modern browsers, so a clean front-end (React or similar) coupled with a solid back-end is essential. I am open to whichever cloud TTS engines or open-source models you feel give the best balance of realism, language coverage and cost efficiency; please outline your reasoning and any licensing factors when you bid.

Core deliverables
• Responsive UI/UX that handles the two input methods (paste text / upload script)
• Voice, language, speed, pitch and format selectors that update in real time
• Server-side generation of the audio plus secure, one-click download links
• Admin area where I can view usage metrics and add or remove available voices
• Deployment to my hosting of choice with clear hand-over documentation

The project is complete once a new user can land on the site, create a voiceover, download it and hear the selected settings reflected accurately in the audio. Looking forward to seeing your approach and timeline.

Skills: PHP, JavaScript, WordPress, Cloud Computing, HTML, Web Development, Audio Processing, API Development

I'm looking for an experienced React Native developer to audit, debug, and stabilize an existing healthcare and fitness mobile app for iOS and Android. The app connects to Bluetooth-enabled exercise equipment to collect and synchronize workout data. I need someone who can investigate Bluetooth connectivity issues, data synchronization errors, app crashes, and other functional bugs. The work includes a thorough codebase audit to identify architectural weaknesses, performance bottlenecks, and potential security concerns. I also need improvements to API integrations, state management, navigation, and overall app reliability. My goal is to bring the existing application to production quality through targeted fixes, code optimization, and regression testing rather than a complete rebuild. I'm looking for a developer with strong React Native, Expo, TypeScript, Bluetooth Low Energy (BLE), and mobile debugging experience who can take ownership of the stabilization process and prepare the app for a reliable production launch.

Due to confidentiality requirements, I'll share the app and codebase once the contract is in place.

- The live site: passive checks only. No denial-of-service, flooding or load testing anywhere. Third-party services are out of scope.
- Window: 5 to 7 working days in the weeks of 9 or 16 November 2026.

Deliverables (two milestones)
1. Testing and a report: each finding with severity (CVSS), steps to reproduce, evidence and recommended fix, plus a one-page plain-English summary.
2. One retest of the fixed findings and a short final confirmation.

Please reply with
1. A fixed price in USD for both milestones.
2. Number of testing days and your earliest dates.
3. Your certifications with their verification IDs (for example OSCP, CREST).
4. A sample report with client details removed.
5. Whether you have tested Supabase or Postgres row-level security before.
6. Confirmation that you will sign an NDA and delete all test data and credentials afterwards.

- Google and email authentication, with renter and landlord roles
- Five-step property listing form with photo upload
- Landlord dashboard (listings, leads, saved properties, profile)
- REST API for all of the above, plus a listing auto-expiry job

*Scope*

Phase 1: Audit (deliver a written report)
Review both repos and produce a prioritised list of issues (critical, high, medium), covering:
- Security: Supabase RLS policies, auth middleware and JWT verification, authorization on every landlord endpoint, input validation, secrets and environment handling, CORS, rate limiting on auth and contact reveal
- Data integrity: schema, constraints, indexes for search queries, migrations
- Error handling and logging on the API
- Next.js: server/client component boundaries, caching, SEO metadata, image optimisation, and anything broken in production builds
- Dead code, duplicated logic, and inconsistent patterns typical of AI-generated code

Phase 2: Fix
Fix every critical issue and as many high-priority issues as the budget allows, in order of priority. Document anything you don't get to.

Phase 3: Production readiness
- Make sure both apps build and deploy cleanly, with production environment configs
- Add basic error monitoring (e.g. Sentry) and health checks on the API
- Write a short launch checklist with remaining risks

*What we're looking for*
- Senior-level full stack experience with Next.js and Node/Express in production
- Strong Supabase knowledge, especially RLS and Auth
- A security-minded reviewer who can judge what really matters before launch versus what can wait

*Use of AI tools*
We encourage using AI-assisted tools like Claude Code, Cursor, or Copilot. The codebase was built with them, and using them well will help you move faster within the budget. That said, AI output needs careful checking, and that's exactly why we're hiring a human expert:
- You must understand and review every change you submit. Don't merge AI-generated fixes you haven't verified.
- Test security and auth changes manually, not just by trusting the generated code.
- Each PR description should explain what changed and why, in your own words.
- Tell us which tools you use and how you use them in your workflow.

*Deliverables*
- Audit report (Markdown or Google Doc)
- Fixes as pull requests with clear descriptions
- Launch checklist and a list of remaining issues

*Budget and engagement*
- $500 fixed, in two milestones: $150 for the audit report, $350 for the fixes and production-readiness work
- Expected effort: about 20–30 hours
- Timeline: 1–2 weeks

*To apply, answer these:*
1. Describe a codebase you've audited or hardened for production. What were the most serious issues you found?
2. In a Supabase + Express app, what are the first three things you'd check for security?
3. Have you worked with Supabase RLS and Auth in production?
4. Your availability over the next two weeks.
5. Which AI coding tools do you use, and how do you check their output before shipping it?

We are looking for a Front-End Developer to create an interactive platform for data import, mapping, and validation. This platform will help users transfer information from external files into our digital products and internal business systems. The project's goal is to simplify the process of importing structured data from spreadsheets and CSV files by providing an intuitive interface. Users will be able to upload files, preview their contents, match incoming columns to the appropriate system fields, identify data quality issues, and review the information before final submission for processing. Instead of requiring users to manually reorganize files or rely on technical support to resolve formatting problems, the application will guide them through a structured import workflow. Users will understand how their data will be interpreted, identify missing or incorrectly formatted values, correct supported issues, and confirm that the information is ready for submission. The initial project will focus on developing a complete front-end experience for this workflow, including file selection, data previews, field mapping, validation feedback, correction interfaces, import summaries, and submission status tracking. The application will connect to back-end APIs for file processing, validation results, and import operations. This role requires a strong understanding of interactive interface development, complex forms, tabular data presentation, state management, and user-friendly error handling. The developer will transform a multi-step technical process into a clear, reliable experience that caters to both technical and non-technical users. The aim is to deliver a maintainable application that improves data imports, reduces avoidable input errors, and lays the groundwork for future enhancements, such as saved mapping templates, scheduled imports, and integrations with additional data sources.

Responsibilities for this position include:

- Develop a responsive data import interface that guides users through selecting a file, reviewing its contents, mapping fields, validating records, and submitting the final import.

- Build file selection and upload interfaces that support specified file formats, initially focusing on CSV and Excel spreadsheets.

- Implement drag-and-drop file selection alongside conventional file browsing options.

- Create a data preview interface that displays incoming records in a structured table with appropriate column headings, row navigation, and clear formatting.

- Implement table interactions such as horizontal scrolling, pagination or virtualized rendering where appropriate, column resizing as necessary, and clear indicators for selected or problematic cells.

- Develop an interactive field-mapping interface that allows users to match incoming file columns to the corresponding fields expected by the destination system.

- Provide suggested field matches based on column names and available metadata while allowing users to review and modify mappings before continuing.

- Display required fields, optional fields, data types, and formatting expectations to help users understand the mapping requirements.

- Implement validation feedback for missing required values, invalid dates, incorrect number formats, duplicate identifiers, unsupported values, and other agreed-upon data quality rules.

- Highlight invalid rows and individual cells to assist users in identifying where corrections are needed.

- Build correction interfaces that allow users to edit supported values, review validation messages, and revalidate records before submission.

- Develop clear visual indicators for valid records, records requiring attention, and records that cannot be imported.

- Create a review and confirmation screen that summarizes the selected file, field mappings, record counts, validation results, and any outstanding issues.

- Implement import progress indicators and completion summaries that communicate successful records, rejected records, and any processing errors returned by the backend.

- Integrate the front-end application with available APIs for retrieving field definitions, uploading files, obtaining validation results, submitting import requests, and retrieving import status.

- Manage application state across the multi-step workflow, ensuring that user selections, field mappings, corrections, and validation results remain consistent as users navigate between steps.

- Handle loading states, empty datasets, unsupported files, failed uploads, expired sessions, interrupted requests, and other common error scenarios, providing clear recovery options.

- Implement safeguards against accidental data loss when users navigate away from an unfinished import or replace a file.

- Ensure that large spreadsheets can be previewed and navigated efficiently without causing unnecessary rendering delays or excessive browser memory usage.

- Develop reusable front-end components for file upload, data tables, mapping controls, validation messages, progress indicators, and other essential features.

We're looking for a senior developer who can jump into our existing system, understand how everything works, and help us make it more reliable and efficient.

We've got a React/TypeScript app running on Vercel and Supabase, along with an AI agent built on Hermes that handles automation through Telegram and connects with platforms like ServiceChannel, ServiceNow, and Housecall Pro.

Right now, our main goal is to move the AI agent off a local Windows machine and into the cloud, make sure all the integrations are running smoothly, and clean up a few issues with our CRM, database, and authentication. We also want better error handling, monitoring, backups, and documentation so the system is easier to maintain and scale.

We're not looking to rebuild everything from scratch. Most of it already works. We just need someone who's comfortable working with APIs, webhooks, AI agents, cloud infrastructure, and complex production systems. Someone who can spot potential issues, recommend practical solutions, and get things done without a lot of hand-holding.

Experience with Hermes, Supabase, Vercel, Docker, AWS, or field service integrations would be a big plus.

We're looking for someone who can start right away, communicate clearly, take ownership of the technical side, and potentially work with us long term.

If you've worked on something similar, we'd love to hear about your experience, how you'd approach improving our setup, and when you're available to start.

I’m building a social-media style chat app focused on private, one-to-one conversations. At the heart of the product are fast, reliable text messages plus secure photo and video sharing between users.

Beyond those essentials, I’m aiming for a clean mobile UI (iOS and Android), robust user authentication, message status indicators, push notifications, and the basic profile screens you’d expect in a modern chat experience. Voice or video calling is not required right now, but I’d like the architecture to leave room for it later.

You’re free to propose the stack—Flutter or React Native on the front end and something like Firebase, Supabase, or a Node/Express API with real-time sockets on the back are all welcome options—as long as it delivers low-latency messaging and secure media storage.

Deliverables
• Full source code with clear project structure
• Deployed backend and database (cloud or self-hosted, your recommendation)
• Step-by-step setup / deployment notes
• Brief admin or analytics view to monitor users and chats

Please outline your proposed tech stack, any past chat projects, and an estimated timeline so we can get started quickly.

We need an expert developer to fix and debug an existing mobile app built with React Native and Flutter. The work includes identifying and resolving issues, improving app stability, and ensuring the app runs smoothly across devices. You should be comfortable reviewing existing code, diagnosing problems, and implementing reliable fixes. Experience with mobile app troubleshooting and performance optimization is important. This is a short-term project for someone who can work independently and deliver a stable, well-functioning app.

We are seeking a professional with at least 10 years of hands-on NetSuite experience, covering administration, customization, and development. The role requires availability during US business hours, and we prefer someone who can start immediately.
If you are interested, please share your updated resume through Upwork, along with:

1. A brief overview of your relevant NetSuite experience
2. Your earliest available start date
3. Your availability during US business hours

I look forward to discussing your experience and the project requirements.

I recently launched a fully responsive React.js website for Mandala Resin Studio that already showcases our handmade resin gifts and includes a custom-order form with WhatsApp contact. The next milestone is to turn this catalogue into a true e-commerce experience.

What I need first is a smooth “add-to-cart → pay → confirmation” flow that feels just as soft and aesthetic as the rest of the site. The solution must:

• Let shoppers complete their purchase online through UPI and Indian payment apps, credit and debit cards, and an optional cash-on-delivery choice at checkout.
• Keep the current React front end; you may extend it (Redux, Context, or your preferred state manager) but avoid rewrites.
• Plug into a reliable Indian payment gateway such as Razorpay, Cashfree, Paytm, or another you recommend, while preserving responsive design across mobile, tablet, and desktop.
• Generate order summaries for both the customer and our admin email/WhatsApp, and update inventory counts stored in simple JSON or a lightweight backend you set up.
• Preserve page-load speed and UI consistency so the shopping journey feels native to the site.

If you have ideas for future enhancements—discount codes, shipping rate calculation, or an admin dashboard—feel free to mention them, but this first phase is all about the checkout pipeline.

Please send a detailed project proposal outlining your technical approach, estimated timeline, and any similar React + payment-gateway work you have shipped. I’m happy to answer follow-up questions quickly so we can get things moving.

Skills: JavaScript, Website Design, HTML, Node.js, React.js, Web Development, Payment Gateway Integration, Frontend Development, MongoDB, Tailwind CSS

I need an experienced developer to complete a newsletter feature inside the existing admin dashboard of my live real estate website.
