What I do

🗄️
Database Engineering

SQL Server architecture, stored procedure optimization, index strategies, and performance tuning. I read execution plans the way others read novels.

Native iPhone apps built with SwiftUI and SwiftData. From concept to App Store — clean architecture, intuitive UX, real persistence.

Data by day.
Apps by night.

I'm a SQL Server DBA with deep experience optimizing systems that can't afford to fail — stored procedures, execution plans, index strategies, the whole stack.

On the mobile side, I build native iOS apps using SwiftUI and SwiftData. I've gone from zero to shipping full-featured apps with persistence, notifications, and custom UI — all from scratch.
