About
I’m a Flutter-centered product engineer with 6+ years of Flutter experience and 9+ years in software development, and I focus on building reliable production web and mobile experiences. Over the last nearly four years, I modernized a multi-product US property-services workflow end-to-end, collaborating on Flutter architecture patterns, dependency injection, responsive layouts, and repository/model structure while keeping teams aligned with resilient delivery practices.
I also enjoy designing performance-aware API contracts and strengthening the full request-to-retry experience in mobile (especially under poor connectivity), backed by Firebase/Firestore and automated testing at scale. I’ve helped lead production incident response practices and participated in Cloud Functions migrations (Gen1 to Gen2), always aiming for stability, observability, and maintainable engineering workflows.

Work experience· 5 roles
Modernized and became a leading maintainer of a core property-turnover workflow, replacing a legacy desktop-oriented experience with responsive Flutter/GetX flows backed by Firebase and synchronized with Dynamics 365. Helped define Flutter architecture decisions (DI, repository/model patterns, responsive layout and extension patterns) across production applications. Designed client/backend API contracts for paginated unit search and provider selection, bounding ranked results and enabling client-side backfill. Investigated connectivity-related photo-upload failures using telemetry and improved resiliency with connectivity-aware local persistence and retry. Sustained high automated-test coverage across large numbers of pull requests and delivered shared pricing logic across Flutter web and provider apps. Co-established PagerDuty-based incident response practices and contributed to Firebase Cloud Functions Gen1-to-Gen2 transition and retirement of legacy functions.
Modernized and became the leading maintainer of a core property-turnover workflow, replacing a legacy desktop-oriented experience with responsive Flutter/GetX flows backed by Firebase and synchronized with Dynamics 365. After stabilization, the workflow operated for ~18 months without a production incident. Collaborated on shared Flutter architecture decisions and implemented reusable patterns (dependency injection, repositories, models, responsive layouts, and extension patterns). Designed paginated unit search and provider selection contracts, bounding ranked results to ~12–15 providers per service while retaining results for client-side backfill. Investigated poor-connectivity photo-upload failures using 30-day telemetry (3,000+ events). Added connectivity-aware local persistence and retry so mobile requests could resume when the network stabilized. Improved automated testing coverage across multiple layers (unit, widget, Gherkin/E2E, integration; plus TypeScript/Jest). Delivere
Served as the sole mobile developer initially, building and publishing Flutter applications with Django backends and REST/SOAP integrations. Later supported hiring by interviewing and onboarding developers, and coordinated backend testing and delivery.
