01 About Me

I'm a Software Engineer at Microsoft with a deep passion for building products that matter at scale. Over the past 7 years, I've gone from building core calendar experiences on Outlook Android to architecting Copilot APIs that power AI features across Microsoft's entire Outlook ecosystem.

My journey through Outlook has given me a rare cross-cutting view — from native mobile development (Kotlin, Swift) to backend service APIs (C#, .NET) to AI/LLM integration. I thrive at the intersection of product engineering and emerging technology.

Outside of work, I'm obsessed with the AI application layer. I ship real products using AI-assisted development — from ideation to App Store release. I believe the best engineers in the next decade will be the ones who master the art of building with AI, not just building AI.
