About this service

Summary

I’ve worked on consumer-facing mobile apps across fitness, exploration, mindfulness, and health, handling everything from framework migrations to complex feature development. My work often involves fixing unstable systems, improving performance, and delivering apps that users can rely on daily.

I focus on clean code, predictable behavior, and mobile apps that scale as product requirements grow.
