Work Experience

Freelance Flutter Consultant

December 1, 2025 - Present

Architected bespoke cross-platform applications for international clients, driving the full software development lifecycle (SDLC) from design to production deployment. Re-engineered legacy codebases to remove critical performance bottlenecks and modernize state management architecture for long-term maintainability and scalability.

Flutter Software Engineer at With U (Fitness)

February 1, 2023 - December 1, 2025

Led architecture and modular design for the With U fitness app using Flutter/Dart, transforming legacy code into scalable and maintainable feature modules. Built cloud-native backend integrations using AWS (S3, CloudFront) and GCP Cloud Functions, ensuring data parity and optimized content delivery for media-heavy features. Automated CI/CD pipelines with CodeMagic to reduce release cycle times by 30–50% and enforce automated testing standards. Collaborated with UI/UX and product teams to deliver smooth interfaces with optimized custom painters/animations for 60 FPS zero-jank rendering. Established enterprise coding standards and performance benchmarks, reducing asset loading time by 50% and APK size by 60% via CDN-backed delivery using AWS S3/CloudFront.

Senior Mobile App Engineer at Cloud Medx (Outsourced by TransData)

July 1, 2022 - February 1, 2023

Collaborated on the design and structural maintenance of secure, scalable mobile health-tech applications, integrating complex REST/GraphQL APIs with remote cloud databases. Engineered a decoupled architecture using MVP (Model-View-Presenter) paired with a local caching layer via Hive for fluid UI rendering during real-time data streaming. Implemented robust local data encryption and secure token-based authentication, ensuring compliance with data privacy standards. Architected a modular monorepo structure to break down monolithic features into decoupled, reusable local packages, improving development velocity and separation of concerns. Mentored junior engineers and led peer code reviews to align with clean architecture principles (SOLID) and secure token-based authentication protocols.
