Sitharaj — Mobile, web and AI. From idea to shipped software.

Portfolio ↗   ·   LinkedIn ↗   ·   npm ↗   ·   Get in touch ↗

Hi, I'm Sitharaj.

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.

Available for freelance projects & consulting

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.
