Python developer needed for PDF/Word document parsing and AI Q&A prototype
Papan was professional, responsive and helpful throughout the project. He helped build and test a local document AI prototype with document search, source-based answers, version comparison and retrieval improvements.
He communicated clearly, made adjustments based on feedback and was honest about the limitations. I appreciated his effort and technical skills, and I would recommend him for AI/document automation prototype work.

Semi-Automated Job Application System Development
Papan did an excellent job on this project.
He brought strong system design thinking, clear communication, and a very practical approach to solving a complex problem. His documentation was detailed and easy to follow, and he showed a deep understanding of both the technical challenges and real-world constraints.
What stood out most was his ability to balance automation with reliability, without overengineering the solution. He identified risks early and approached them thoughtfully.
Highly recommend working with him. Thank you Papan!

Hiring: Full Stack Developer Intern/Freelancer – Python, Django, Streamlit, AI
It was great working with Papan. He understood our SaaS problem, considered multiple adhoc requirements and was able to create the solution as per expectation. He prioritized the deliverables at times when it was needed the most. We would love to collaborate with Papan again in the future.

About Papan
AI Full-Stack Engineer | RAG - AI Agents - Django/FastAPI - React
100%
Job Success
Kolkata, India - 8:21 am local time
I build AI-powered SaaS products that run in production — not demos. If you need someone to own the full stack, from the LLM pipeline to the backend to the React frontend, that's exactly what I do.
I'm Top Rated with 100% Job Success, and I've shipped real systems: an AI document Q&A platform with source-cited answers, a HIPAA-compliant compliance app with automated audit trails, AI voice agents, and fleet-compliance software handling FMCSA/DOT rules end-to-end.
Where I create the most value
• AI & LLM products — RAG pipelines, AI agents, chatbots, and voice interfaces using OpenAI, Claude, and Gemini. Built to handle real users, with retrieval that actually returns the right answer.
• SaaS backends — Django/FastAPI APIs with secure auth, RBAC, webhooks, Celery jobs, and PostgreSQL. Architected to scale from MVP to thousands of concurrent users.
• React frontends — clean, responsive UIs with real-time streaming (SSE/WebSocket), TanStack Query, and Tailwind/Shadcn.
• Integrations & automation — Stripe, Twilio, OAuth, n8n, and ETL pipelines that just work.
How I work
Discover your goal → agree the architecture upfront (data models, API contracts — no mid-project surprises) → build with frequent demos and clean commits → hand over full docs and a system you can maintain.
Stack: Python · Django · FastAPI · Celery · Redis · PostgreSQL · React · TypeScript · Tailwind · Docker · AWS · LangChain · OpenAI/Claude APIs · Stripe · Twilio
Send me your repo, brief, or idea and I'll reply with a concrete architecture proposal and estimate — no fluff. Let's build it right.
