Software engineer · Mobile & web apps · React Native · Open source
Hi, I'm Himanshu.I build mobile apps, web apps, and open-source developer tools.
Currently a Software Engineer & Release Manager at Tap Health, an author of open-source developer tools with 26,100+ npm downloads, and founder of SnoozeWar, live on Google Play in 176 countries. I ship mobile and web apps, drop down to native code when the platform demands it, and own the release pipeline to both stores.

Skills
What I am good at
End-to-end product ownership
I built and own SnoozeWar alone, end to end: product, design, app, backend, marketing site, legal, and store submission. It is live on Google Play. At Tap Health I own features across the whole lifecycle: PRD, prototype, task breakdown, team alignment, and delivery through other developers to production.
Release management & CI/CD
40+ releases across the App Store and Play Store on a pipeline I built and maintain. Quality is automated, not promised: custom lint rules gate every merge, and tests, unit to end-to-end, run in the pipeline, not as an afterthought.
AI-accelerated engineering & workflow automation
I get real work out of AI, not demos, and I automate the workflows around it. I wrote the Figma-to-code guidelines behind Tap Health's Claude + MCP design-system pipeline, and built a Figma plugin that audits design files so AI code generation actually works.
Native iOS & Android depth
I write the Swift and Kotlin underneath React Native. When an npm package is unmaintained, I replace it with my own rather than build on someone's abandoned code; both of my published libraries started that way. The native surface I have shipped is wide: real-time Android shaders, device sensors and wearables, HealthKit, Health Connect, Samsung Health, and the OLA Maps SDK.
