Node/React Internal Tool Development

@shrec

I can take your existing architecture and turn it into a clean, production-ready Node.js + React application that meets your acceptance criteria end to end. I’ll build a secure REST API with JWT auth, role-based access, PostgreSQL integration, and rate limiting, alongside a React front end with well-structured state management, performant data visualizations, and robust file uploads. All work will be pushed in clear, granular commits to your private Git repo, fully linted, tested, and documented for easy handover. I’m comfortable working against provided schemas, wireframes, and test cases and can align quickly on milestones to get this client-ready.

@kishanbwts

Your plan is solid and clear. I can build this tool following your architecture to deliver secure user auth with JWT and role controls, smooth file uploads with progress bars, and interactive charts that fetch data reliably from your REST API. In a past project, I helped a SaaS client build a dashboard with React and Node, similar stack and features, including JWT auth and PostgreSQL integration. We met strict API testing and performance goals as you describe. A quick check: do your rate limits apply per user or IP? Also, for file uploads, do you expect resumable uploads or just single requests? Both affect backend design. I’ll keep commits focused and provide thorough docs so you can track progress easily. Once we agree on milestones, I’m ready to start bringing your wireframes to life with clean, tested code right away.

@planDapps

TURNING A SOLID ARCHITECTURE INTO A PRODUCTION READY TOOL You already have the hard part done the architecture. What you need now is clean execution that meets real production standards, not just “works on my machine.” At Plan D Studios, we’ve spent 12+ years building custom web applications, internal dashboards, and API driven tools where performance, security, and maintainability actually matter. For this build, we’d focus on: • Secure JWT based authentication with clear role separation • Clean RESTful API implementation backed by PostgreSQL • React frontend using functional components to consume APIs and render interactive charts • Reliable file upload/download handling with progress feedback • Lint clean, test covered code with granular Git commits and clear README setup Everything is built in house with an emphasis on web development, custom software, dashboards, automation, and API integration no shortcuts, no fragile logic. Are there any edge cases around file storage or user roles we should account for early? Happy to review the repo and get started. Regards, Haider

@juanestebana17

Hi there, I have 6+ years building production-grade Node.js back-ends and React front-ends for enterprise tools, including REST APIs, PostgreSQL, and JWT-based auth. I will deliver a clean, production-ready internal tool with secure sign-up and role-based access, interactive charts from your REST endpoints, and reliable file upload/download up to 50 MB with progress indicators. The back-end will be Express-based, connected to PostgreSQL with JWT auth and basic rate limiting; the front-end will use React (hooks) with Redux Toolkit or Context and charts via Chart.js. I’ll push code to your private Git repo, document setup in a README, and keep granular commits. I’ll ensure cross-browser reliability (Chrome, Firefox, Edge), API endpoints with correct status codes, Lighthouse scores above 90, and ESLint/Prettier-compliant tests (Jest + RTL). What is your target MVP milestone, and are there any non-functional requirements (SLA, audit logging, data retention) I should account for in the plan? Best regards,

@tobiask5

Hi How are you? I hope you are doing well. I have extensive experience in that kinda projects and i have done so many similar projects. I hope we work together. Thanks

@jonhw5

Hello, thanks for posting this project. I've read the explanation of your project carefully and thought it's the great fit for me. Because: I'm a full stack engineer with strong experience owning features end-to-end from frontend implementation through backend architecture, data modeling, auth, and third-party integrations. I've worked extensively with React (Javascript, Typescript), Vite, and I have deep practical experience using Supabase (Auth, PostgreS, RLS, Storage) as a primary backend. I'm comfortable taking over existing codebases, making pragmatic technical decisions, and shipping production-ready features with minimal direction. About my experience: I've built and integrated complex workflows involving PDFs, structured data, and automation, and I've used NodeJS (ExpressJS, NestJS) to securely integrate external APIs, including AI services. Security, access control, and reliability are always first-class concerns in my work. When developing a project, I always consider security as the top priority, followed by project quality, including structure and code quality (clean, maintainable, well-structured code). This four-month sprint model aligns well with how I work: focused execution, clear deliverables, and real progress to production. Could you share your preferred workflow for tracking progress and communicating day-to-day implementation updates? Looking forward to hearing from you. Warm regards, Vitalii.
