I’m a Software Engineer at Square Health Ltd. focused on building reliable, user-centric mobile apps with Flutter and React Native. Over 6+ years, I’ve shipped healthcare and commerce products end-to-end—from app architecture and performance tuning to Play Console release workflows and analytics.

Recently I led key work on Jotno (telemedicine ecosystem) and contributed to Confidence Reseller and EDCR, improving speed, stability, and UX across Android and iOS. I enjoy clean architecture, state management (Riverpod/Redux), API integrations (Retrofit/Dio/Axios), and thoughtful UI polish.

I also teach on YouTube, creating practical courses in Web (JavaScript, React, HTML/CSS), Flutter, Figma, and React Native—sharing field-tested patterns that developers can apply immediately.

When I’m not coding or teaching, I mentor juniors, review app releases, and align product decisions with business goals.
Let’s build something people love.
