Notes on Android, architecture and AI tooling
Android at the core, system design around it
I'm a Senior Software Engineer with more than ten years of experience building production apps. Android is my core, and my strength is the system around it: architecture, API design, and the technical decisions that keep a product reliable and easy to change as it grows.
At Bitpanda I've led trading features like Staking, Margin Trading and Real Stocks for a platform with 8M+ users, from the RFC to production rollout and monitoring. I work closely with backend on GraphQL contracts and with design on the design system, and I led my team's adoption of AI-assisted development with Claude Code.
Before Bitpanda I modularized the Neshan maps app and worked on its Map SDK, and built commerce and booking apps at several companies. Outside work I build Lexicon, an open-source Kotlin Multiplatform app, and mentor developers on ADPList.
