Muddassar H.

I build full-stack and AI-powered systems for startups and small teams — from Django/FastAPI backends to production AI agents and automation pipelines. Recent results: a Stripe billing backend that helped a SaaS client accelerate monetization 3x, an AI email auto-responder saving clients 5–10 hours/week, and an AI resume-screening system that cut hiring time 40%. I've also shipped RAG knowledge chatbots, voice AI assistants, and multi-agent QA automation systems. Stack: Python, Django, FastAPI, Spring Boot, React, PostgreSQL, Docker, AWS. On the AI side: OpenAI API, LangChain, RAG pipelines, n8n workflow automation, and custom AI agents. What you get: clean code that holds up past the demo, honest timelines, and someone who scopes the actual problem before writing a line of code — not just the ticket as written.
