About
I make mobile apps thatfeel inevitable.
I believe a good app is one where the user forgets they’re using software at all. After 5+ years working with Swift, Objective-C and Flutter — across mobile banking, fintech and enterprise super-apps — I still hold every product I touch to that same bar.

Performance first
120fps scrolling, sub-second startup, and reaching for the right profiler before writing new code.

Detail obsessed
Haptics, motion curves, kerning — the things users feel before they consciously notice them.
