About

From lead developer to CTO

Engineering leader with over a decade building software end to end — from native mobile apps to multi-tenant SaaS platforms and AI systems.

My path runs from lead Android developer to senior Java engineer to Chief Technology Officer, so I move comfortably between hands-on architecture and technical leadership.

Today I focus on retrieval-augmented AI, platform engineering, and the reusable foundations that let small teams ship serious products.
