The developer
One engineer, end-to-end ownership
From architecture and UI to deployment and monitoring, I take products the whole way. Six years of shipping Kotlin apps, Flutter builds, React platforms and SaaS dashboards means fewer handoffs, tighter timelines and code that stays maintainable.
What I do
Product engineering across every screen your customers use
Android App Engineering
Production-grade native Android products written in idiomatic Kotlin with clean architecture, offline-first data and biometric security.
Cross-Platform Apps
One codebase, every screen. Flutter and React Native builds that ship to Android, iOS and desktop without compromising on native feel.
SaaS Product Development
End-to-end SaaS: multi-tenant data models, role-based access, subscription billing and analytics dashboards that owners actually use.
Cloud, Hosting & DevOps
Deployment, migration and hardening on Firebase, GCP and AWS, with Linux server administration and zero-downtime domain moves.
SEO & Growth Basics
A light-touch add-on, not the main act: technical SEO, on-page structure and the essential marketing tactics that make a launch land.
