What I'm looking for

I seek leadership roles building and scaling mobile/platform/SDK teams where I can drive reliability, security, developer experience, and mentor engineers while delivering measurable product impact.

I am a Software Engineering Manager with 10+ years building and scaling high-availability mobile and web platforms, including developer-facing SDKs and cross-platform solutions. I lead by example with an empathetic management style and strong ownership of reliability, security, and developer experience.

I've led platform and mobile teams supporting 75M+ DAUs, drove SDK and platform initiatives across Android, iOS, React Native, Flutter and Kotlin Multiplatform, and improved delivery metrics through observability, automation, and security hardening. Key outcomes include reduced MTTR, increased feature delivery, major merchant and partner go-lives, and sustained high crash-free rates.

I enjoy hiring and mentoring engineers, defining technical strategy, and building platform tooling and processes that scale teams and products while maintaining a high technical bar and regulatory compliance.
