Project details
Add AI to your product done right, so it works in production, not just in a demo. I integrate ChatGPT, Claude, and other LLMs into existing web apps and SaaS platforms: AI chat, assistants trained on your own content, document processing, and smart automations built by a full-stack engineer, not bolted on.
What I can build into your app:
• ChatGPT / OpenAI / Claude API integration
• AI chatbot or in-app assistant (with streaming responses)
• RAG assistant trained on your docs, site, or knowledge base (semantic search + citations)
• AI content / document generation
• AI document processing & data extraction (Vision AI, OCR)
• Prompt engineering, guardrails, and cost/latency optimization
Works with your stack — Next.js, React, Node.js, Python/FastAPI. I integrate into your existing codebase or ship a clean API/microservice.
Recent AI builds:
→ RAG Document-QA Assistant — LangChain + OpenAI + ChromaDB, 95%+ accuracy, <3s responses
→ AI Lead-Scoring SaaS — 99.86% prediction accuracy (Python, FastAPI, React dashboard)
Message me before ordering with what you want the AI to do and your current stack — I'll confirm scope and the right model for the job.

Next.js expert needed - 4h/$20 deal
Magnificent experience! Highly knowledgeable and very easy to work with. Was able to fix some bugs in a short time that other devs weren't able to fix in a week. We'll surely hire him again.

Job Success
Islamabad, Pakistan - 4:33 am local time
Clients usually come to me in one of three situations:
• They have an idea and need an MVP fast and built right. I take you from concept to a working, scalable product in weeks, not months.
• They need AI integrated into a product. LLM features, OpenAI-powered functionality, AI document processing, in-app chat built properly so it works in production, not just in a demo.
• They have a prototype that breaks at scale. Often AI- or no-code-built (Lovable, Bolt, v0, Cursor). I re-engineer it into something production-grade: secure, performant, maintainable.
What working with me gets you:
• Full-stack ownership frontend, backend, database, auth, deployment.
• Production discipline clean architecture, security hardening, proper error handling. (Background in security auditing and computer vision.)
• Speed without the tech debt, and a clean handoff when it's done.
Stack: Next.js, React, TypeScript, Node.js, FastAPI, Python, PostgreSQL, Supabase, Firebase, React Native, Docker plus AI/ML integration (OpenAI, Google Gemini Vision, LangGraph, LSTM/GRU neural networks).
Recent work: Built an autonomous AI lead-scoring agent with adaptive model retraining (AUC 0.9986) deployed live on Railway and a Vision AI card-scanning SaaS platform with Google Gemini that processes trading cards in under 3 seconds, complete with a print studio and public verification certificates.
If you want a developer who ships fast but builds it to last, message me - happy to scope it on a quick call.
