About Me

Android Engineer & Module Owner building products used by thousands of merchants

I'm an Android Engineer at Zoho Corporation where I own the Restaurant POS module end-to-end — from technical roadmap to release management. I don't wait for tickets; I identify problems and ship solutions. I was the first engineer to champion Jetpack Compose adoption on my team, built the design system that's now the standard, and improved our Play Store rating from 3.9 to 4.3 through a self-initiated feature.

Outside work, I ship my own products — superwrite.app is live in production.

API Load Time Optimized

Self-Initiated

I don't wait for tickets

These are problems I identified and solved on my own initiative — no one asked me to do them.

Product + Engineering
In-App Rating System

Owned PM and engineering. Designed non-intrusive UX with EWMA algorithm for optimal trigger timing. Result: Play Store rating improved from 3.9 to 4.3.

Architecture
Jetpack Compose Adoption

First engineer to champion Compose on the team. Built design system and component library that's now the team standard for all new feature development.

Architecture
Hilt Dependency Injection

Let's build something great together

I'm open to discussing Android engineering roles, especially those involving scale, architecture ownership, and product impact.
