About
React Native, in production
I'm a Senior Software Developer with 5+ years in mobile application development, focused on React Native for Android and iOS. Most of my work is in production apps — building features, improving performance, and keeping large codebases maintainable over time.
At FoodHub I work on large-scale food-ordering apps on both the merchant and customer side. A lot of my time goes into the menu management system — Edit Menu workflows, nested modifiers, and optimizing Redux for large menu data — alongside production issue analysis, UI improvements, and React Native upgrades.
Before FoodHub, I was the primary React Native engineer at Betamonks. I built several apps from scratch across healthcare, diagnostics, and fintech, helped set up the team's React Native practices, and ran a two-week internal training program for other developers.
