01 — About
A senior engineer with an AI obsession.
I'm a Lead AI Engineer with a foundation in senior full-stack development. I bridge complex machine-learning models and robust web applications — making AI a core driver of business value, not a checkbox feature.
My work spans the end-to-end lifecycle: fine-tuning LLMs, architecting retrieval-augmented generation systems, building scalable Node/Python infrastructure, and shipping product on Next.js, Flutter, and GCP. Most recently I led AI engineering at Kuanta, where our agents reduced startup-evaluation time by 70%.
I care about clear interfaces, fast iteration, and code that reads like prose. Always learning — currently obsessed with agentic systems and edge-deployed inference.
