I help startups and product teams build and modernize mobile applications, with 13+ years across mobile and web. My main focus is Android and Kotlin Multiplatform, alongside AI integrations and developer tools.
I build cross-platform apps with Kotlin Multiplatform, React Native, and Flutter, web experiences with React and TypeScript, and open-source libraries that make everyday development easier.
Based in Chennai, India. Building for developers everywhere.
| What you need | How I can help |
|---|---|
| A mobile MVP or new feature | Android and cross-platform development, API integration, release preparation, and handover |
| An existing app improved | Architecture review, performance investigation, prioritized fixes, and CI/CD improvements |
| AI connected to your workflow | Custom MCP integrations, TypeScript SDKs, and developer utilities |
We start with the problem, agree on scope and milestones, and define what a successful delivery looks like.
