About

Mobile is not just what I do —
it's what I love.

I live and breathe mobile development. From crafting fluid iOS experiences in Swift and SwiftUI to diving deep into app security, reverse engineering, and CI/CD automation — every layer of the mobile stack genuinely excites me.

Over 15 years across iOS, Android, and cross-platform development, I've built everything from trading platforms and POS systems to home security apps and health coaching tools — always pushing the boundaries of what mobile can do.
