Most people building AI products right now are stuck at the prototype stage. The chatbot works in a notebook, the agent runs on a laptop, and then it hits real traffic and falls apart. That gap between demo and production is exactly where I work. I spent the last few years as the lead AI engineer at a KYC company where the system could not afford to fail. 100,000+ identity verifications a day, enterprise clients in regulated industries, strict SLA requirements. I built and ran the entire AI pipeline there: document OCR, computer vision models, LLM-based extraction, the inference infrastructure behind all of it. At one point I took the GPU bill from $20K/month down to $7.5K without touching accuracy, just by rearchitecting how LLM inference was served. That kind of work teaches you to think about AI very differently than someone who has only ever built demos. Right now I am focused on freelance AI projects. Specifically: ✔️Chatbots that actually work: RAG-powered, grounded in your data, not hallucinating nonsense. Built with GPT-4o, Claude, or open-source models depending on your budget and privacy needs. ✔️AI agents that do real things: browse, search, write, call APIs, make decisions. Not just a prompt chain. Actual autonomous workflows using LangGraph, CrewAI, or AutoGen. ✔️LLM backends that scale: if you have something working small and need it to handle real load without breaking the bank, that is a problem I have solved before. ✔️Domain-specific AI for fintech, healthcare, and edtech: I have built financial dashboards with AI insights, patient management systems, and adaptive learning tools. I understand the constraints in each of these spaces. I do not take on work I cannot do well. If you send me a project and it is not a fit, I will tell you. If it is a fit, I will move fast, communicate clearly, and deliver something you can actually use. If you are building something real in AI and need someone who has been in the engine room of a large production system, let's talk.
