01About

Curious by nature. Precise by practice.

Self-taught software developer focused on scalable systems, thoughtful problem solving, and code that stays readable long after it ships.

From responsive commerce platforms to secure APIs and real-time communication, I care about the details that make software reliable, fast, and easy to evolve. I work with agentic AI, retrieval-augmented generation (RAG), coding agents, and prompt engineering to streamline repetitive workflows and build context-aware solutions—while keeping every outcome grounded in human review, security, and sound engineering judgment.
