Architected and delivered Flutter mobile applications for a consumer fintech platform from scratch, owning the full lifecycle from design through production and documentation. Integrated multiple third-party SDKs and REST APIs with a strong focus on security and data integrity. Built dynamic, document-driven UI flows for gift card issuance and redemption, handling complex data states and edge cases gracefully for end users. Produced comprehensive technical documentation covering architecture decisions, API contracts, and maintenance guides. Established CI/CD pipelines, automated linting, Git workflows, and code review standards, ensuring a stable, reproducible codebase. Collaborated with non-technical stakeholders to iteratively refine UX based on real usage feedback.

Delivered two Flutter applications — consumer-facing and staff-facing — for a fast-paced remote engagement, independently meeting delivery deadlines. Integrated third-party SDKs and real-time APIs (WebSockets) for QR-based ordering and live order status synchronization, resolving integration edge cases efficiently. Built shared widget libraries and reusable components across apps to improve consistency and simplify future maintenance. Conducted thorough testing and debugging prior to each release, ensuring high-quality deliverables across App Store and Play Store submissions.

Ongoing production Flutter applications supporting daily operations across factory, warehouse, inventory, and retail environments, where reliability and stability are non-negotiable. Triaged complex bugs and production crashes end-to-end, delivering fixes without regressions. Implemented offline-first data handling using Drift for local persistence and background synchronization. Profiled and optimized rendering, memory, and networking performance to support ~50% user growth while maintaining stability. Produced technical documentation detailing architecture, API contracts, and operational workflows to enable smooth onboarding and maintenance.
