I build AI automation that a business actually runs on: agents, RAG pipelines and end to end workflows wired into the tools a team already uses. LangChain and LangGraph orchestration in Python and FastAPI, Claude and OpenAI integrations, vector search on Pinecone and ChromaDB, with n8n, Make or Zapier as the no-code layer when that is the right call.

Most AI work dies in the gap between a model that works in a demo and a process that works on a Monday morning. Closing that gap is the whole job. Clients I have built for include Trukkin (logistics), LGFG Fashion House (fashion), Ultrassure (insurance), Genvision (climate tech), Bowery Boost (performance marketing), Moor Marketing (lead generation) and Ta3swim (ecommerce).

Istanbul, UTC+3. I overlap 09:00 to 13:00 US Eastern every weekday and answer inside 4 hours outside that window. You work with me directly. I write the code myself.

Single and multi-agent systems, LangChain and LangGraph orchestration, Claude and OpenAI integrations, MCP servers and connectors, function calling, human approval gates wherever a mistake is expensive, plus evaluation and guardrails so you can tell whether the thing is actually working.

A workflow that ran fine for months and then stopped. An agent that answers confidently and is wrong. A prototype that works on one laptop with the API keys sitting in a file. I diagnose it, fix it, and leave it on a footing where it keeps running: logging, error handling, retries, version control, permissions. This is most of my current work. Three of my active contracts are improving and extending systems that were already in production, including a weekly ML agents program running since February 2025.

Retrieval that stays accurate as the document set grows, with source citations so any answer can be checked. Chunking, embeddings, Pinecone, ChromaDB, GraphRAG and evaluation. When a first attempt disappoints, the problem is almost always retrieval, not the model. Also support and sales assistants grounded in your own data, with escalation to a human when confidence is low.

𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐒𝐲𝐬𝐭𝐞𝐦 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 Two way syncs between systems that were never designed to talk to each other. APIs, webhooks, and the payload changes that quietly break things overnight. CRM integration including ZOHO, internal tools, email, databases and data flows across your stack.
