About

Mobile first. Product minded.

I build cross-platform mobile applications with Flutter and take ownership from implementation and API integration through testing and production releases.

My recent work includes enterprise employee workflows, financial applications, AWS Cognito authentication, biometrics, Firebase, Riverpod, and REST APIs. I also build full-stack products with Next.js, TypeScript, Supabase/PostgreSQL, and payment integrations.
