About Me

Bridging Mathematics &
Scalable Architecture

Hello! I am a Senior Full-Stack Engineer and Product Architect with a strong mathematical foundation. I specialize in system architecture, real-time systems, AI-integrated applications, and multi-tenant SaaS platforms across government, enterprise, and education sectors.

My passion lies in translating complex mathematical models and algorithms into scalable, production-ready software solutions. Watch my brief introduction video to learn more about my background, vision, and how I build systems.
