AI Agent Developer: RAG, Chatbots, Python Automation

Over mij
I build AI agents that answer from your own documents, with citations, so nobody has to trust a made-up answer.
I am a Python engineer with 10 years on backend and data systems, now working almost entirely on production AI - the kind that still works a month after the demo. I build RAG chatbots and agents, document extraction pipelines, and n8n automations with alerting so you find out when something breaks instead of your customers.
I scope small and deliver early. If you are not sure your idea is even feasible, describe it and I will tell you straight.

- Built a GenAI document extractor that turns thousands of dense PDF pages into validated JSON (Python, Flask, Gemini, PyMuPDF). - Built a chat conversation app on Google Vertex AI: model selection through Model Garden, deployed model endpoints, and answer-quality evaluation with RAGAS against a ground-truth set. (Vertex AI Agent Builder / Agent Engine: NOT used in a real use case - do not claim.) - Cut LLM processing overhead by about 30% on that pipeline by tightening what gets sent to the model, without losing output quality. - Built a RAG-based "GenAI Playground" for internal document Q&A; recognised with a company Reward & Recognition award.
