About

What I can help you with:

→ Integrating LLMs (OpenAI, Deepseek, etc.) into your product
→ Fine-tuning models on your data for better results
→ Building the full product around it — backend, frontend, API
→ Turning a messy AI prototype into a production-ready system

I work well with founders and teams who have a clear goal but need someone who can own the technical side end to end — without hand-holding.
