About Me

I'm an Android Developer based in New Delhi, India, building production-grade mobile applications. I specialize in Kotlin, leveraging modern Android practices to deliver performant, user-friendly apps that scale.

My expertise spans Clean Architecture (MVVM), Jetpack components, asynchronous programming with Coroutines and Flow, and seamless REST API integration — writing code that's not just functional, but testable and maintainable.

Beyond Android, I've explored AI & automation — building an Email Agent using LangGraph and OpenAI APIs, gaining hands-on experience in LLM orchestration, prompt engineering, and agentic workflows.
