Who I am
Engineer, builder, open-source contributor.

My strengths include state management (Bloc, MVVM), Flutter layered architecture, clean architecture, and modern CI/CD practices. I also bring strong backend experience with TypeScript/Node.js, API integration (REST/GraphQL), and cloud infrastructure (GCP/AWS). I'm comfortable leading teams and projects, driving complex technical initiatives from concept to production, and I care deeply about engineering excellence, scalable architecture, and exceptional user experiences.
