personAbout Me

Product-First
Engineering Philosophy

I architect robust backend systems and scalable REST APIs using .NET Core & Dapper ORM, while building cross-platform mobile apps with Flutter. My engineering approach prioritizes clean architecture, security-first design, and data-driven decision making — from fintech platforms processing thousands of daily transactions to AI-enabled citizen service portals.
