01 — About

I'm a Flutter engineer based in Pune, India, currently building Verto Pay — a live remittance app processing $25B+ across 190+ countries — on a six-person team. My focus: BLoC, clean architecture, and dependency structures that let payment flows scale without breaking.

Before Verto, I worked on stock broking and trading platforms, where real-time data and order flows had to stay correct under pressure. That's why I default to defensive architecture — typed error handling, clear use-case boundaries — over shortcuts.
