I’m a results-driven Flutter mobile developer with 4+ years of experience architecting and shipping high-performance applications. I focus on reducing technical debt, accelerating feature delivery, and delivering reliable user experiences through SOLID principles and clean, scalable UI systems.

In my recent work, I helped scaffold the architecture and initial phases of the Cinemark app redesign by building a reusable UI Kit library, accelerating front-end feature delivery by 25%. I also refactored monolithic widgets into modular, testable components, reducing legacy technical debt by 5%, and migrated critical legacy endpoints to a Dart Backend-for-Frontend (BFF) gateway to decrease mobile-side data parsing overhead by 30%, improving screen-load performance and security.

At Globaledb, I developed enterprise management applications with role-based access control (RBAC), improving operational efficiency by 20% across 5+ partner enterprises. I engineered secure biometric authorization workflows that reduced login friction and improved authentication speed by 15%, and collaborated in agile teams to ship cross-platform features with 98% crash-free sessions in production.

I also bring strong hands-on project experience: Psycho2Me uses Firebase as a BaaS to deliver near real-time synchronization (<1s latency) and builds 15+ reusable UI widgets via clean layer separation. FincaApp implements robust offline mode using SQLite/Isar for 100% data persistence during unstable rural networks, while Liberum partners on a multi-tenant platform using Supabase Edge Functions to automate billing and match emails—cutting administrative manual work by an estimated 80% while maintaining on-time Scrum sprint delivery.
