You will get a full-stack web app built with React, Next.js, Node.js or Python
Project details
You will get a modern, production-ready web application built end to end - frontend, backend, database and deployment. I am a full-stack developer specialising in React, Next.js, Node.js and Python, with deep experience adding AI features (chatbots, RAG search, automation) when your product needs them. I have shipped real products that run daily without supervision. You get clean, maintainable code, responsive design, secure auth, fast load times, full source code, CI/CD deployment, documentation and a walkthrough at handover. I communicate clearly, demo progress regularly and stick to agreed milestones - no surprises, just a working product.

Multi-Language (i18n) + Per-Locale VAT Support for QR Table-Ordering SaaS
Hafiz did excellent work on our QR ordering platform — added full multi-language support (English/German) and per-café VAT/currency handling, integrated cleanly with our existing Stripe setup. He was detail-oriented, communicated clearly throughout, and delivered exactly what we needed for our German market expansion. Would definitely work with him again.

About Hafiz
Full-Stack Developer | AI/RAG Systems, Next.js & Python

Job Success
Chester, United Kingdom - 4:13 am local time
I build full-stack web applications and the AI systems inside them , from Next.js/React frontends and Python/FastAPI backends to RAG pipelines and AI agents that read your documents and cite every answer back to the source.
Most "AI tools" work in a demo and fall apart on real, messy data. I build for production: complete applications with proper auth, databases, and deployment — plus retrieval-augmented generation (RAG) pipelines and autonomous AI agents when the project calls for it.
WHAT I BUILD:
Full-stack web apps — Next.js frontend, Python (FastAPI/Django) or Node backend, PostgreSQL/Supabase, Stripe billing, AWS/Vercel deployment
RAG & document intelligence — cited, auditable answers across contracts, policies, and records (OCR ingestion, hybrid retrieval, reranking)
AI agents & workflows — multi-agent systems that read documents, validate data, and act on it with human review built in
Anti-hallucination architecture — citation enforcement and structured-output validation so AI features never invent an answer
RECENT RESULT:
For a content team drowning in scripts and briefs, I built a RAG system that flags inconsistencies automatically and traces every output to its source.
"Hafiz didn't just build us an AI platform. He took the time to understand how our content team actually works." — Client review
HOW I WORK:
I learn your workflow and stack first , what needs building, and where AI actually adds value vs. where it's unnecessary
I ship a working version fast so you're testing real functionality within days
I harden for edge cases and production reliability before adding anything else
As your product grows, I keep tuning both the application and any AI components against real usage
Whether you need a full application built end-to-end or AI capabilities added to an existing one, let's talk. Free 30-minute call to map out what you actually need.
Skills: Next.js, React, Python, FastAPI, Node.js, PostgreSQL, RAG, LangChain, LangGraph, AI Agents, OpenAI API, Claude API, Pinecone, pgvector, Stripe, AWS, Docker
