About

AI/ML engineer with 8+ years building intelligent applications. I work across Python, Rust, TypeScript, and Go, leveraging LLMs (Claude, GPT-4, Llama) for agent systems, RAG pipelines, and AI-assisted development workflows. Experienced with vector databases (Pinecone, Weaviate), embedding models, and production ML systems.

I embrace AI-augmented coding with Cursor, Claude Code, and GitHub Copilot to accelerate development while maintaining code quality.
