About
Building Android apps first, while staying sharp across modern web product work.
My primary focus is Android development with Kotlin and Jetpack Compose. I’m also comfortable with Java, XML, and the Android SDK, and I’ve worked with supporting technologies such as Firebase, Room, and Ktor in modern mobile stacks. Alongside Android, I spend a lot of time building web products with React, Next.js, Tailwind, Supabase, and PostgreSQL, which helps me bring a broader product perspective to the work.
Core Expertise
Kotlin, Jetpack Compose, Android SDK, Java, XML, and modern native Android patterns.
Supporting Stack
Firebase, Room, Ktor, Supabase, and PostgreSQL for shipping product features end to end.
Product Lens
I care about information hierarchy, responsiveness, interaction quality, and interfaces that feel intentional rather than assembled.
Web Expansion
React, Next.js, and Tailwind let me take on serious side-project and client web work, not just experimentation.
Career
Professional mobile development since 2022, with ongoing product work across web and backend.
Since September 2022, my work has centered on building modern Android experiences while also growing a broader product stack through web development, backend integrations, and independent product work.

Alongside main role
Web development with Next.js
