Waqas A.
Full Stack & AI Engineer | RAG, LLM Agents | Python, React, Node.js
I build systems that actually hold up in production, not demos that break on the tenth query. What I do most: RAG systems. Document and knowledge-base search that returns the right answer, with chunking, embedding and retrieval tuned to your data instead of copy-pasted defaults. Conversational agents. Support and sales chatbots that connect to your real APIs, so they answer from live order, inventory or account data rather than a static FAQ. AI automation. Manual back-office work replaced with agent workflows using LangChain, LangGraph, n8n, Make and Zapier. Keeping it reliable. Evaluation suites, output guardrails and token-cost optimization, so quality does not drift and your API bill stays predictable. I also build the full application around the AI, which is usually where these projects stall. Ten years of full stack work: Python, TypeScript, React, Next.js, Node.js, FastAPI, Django, PostgreSQL. I have shipped 15+ products across fintech, e-commerce, logistics and healthcare, including a platform that scaled past 10,000 monthly users, plus heavy Amazon SP-API and Shopify integration experience. I have spent most of my career contracting, so I am used to owning a project from the first call to deployment and handover. Send me a message with what you are trying to build and I will tell you honestly whether I am the right fit and what I would do first.
