Scaling mobile platforms with React Native & TypeScript. Brewing reliable code, GitHub spells, and caffeine-fueled engineering quests. ☕✨

I’m Darshan Jain, a mobile software engineer passionate about crafting performant, developer-friendly apps with React Native, TypeScript, and modern tooling.

I thrive at the intersection of product and platform, shaping architecture that scales, building robust developer experiences, and sweating the small details that make great mobile products.

Currently, I lead mobile development at Vetster, a virtual care platform for pets. My work focuses on architecture modernization, performance optimization, and streamlining developer workflows as the product and team scale globally.
