Over 6 years of experience driving feature delivery and modernization across QuickBooks Mobile — global search across multiple domains, a new My Business tab with an Expenses overview, and rebuilding decade-old features on a modern Kotlin/Coroutines/Compose stack. Customer-focused throughout, with a constant emphasis on usability and reliability. This work impacted millions of users across the USA, UK, Canada, and Australia.

Developed and maintained Google Assistant across a range of TV hardware — a system app that behaves differently from a regular app. I re-architected the fragile app-dismissal logic (driven by user interaction, timeout, or server response, each with its own animation) into a clean, modular State Machine that was far easier to reason about and extend. Alongside it, I profiled and improved performance and responsiveness on lower-end devices and raised test coverage to keep the new behavior stable across releases.

Built Meu Vivo, the main consumer app for Telefónica Vivo, Brazil's largest telecom, letting users manage their account balance, bills, and data usage. I helped define the library stack and the architecture for component communication across layers, and introduced reactive programming with ReactiveX as the approach for handling state changes. I drove Kotlin adoption starting a few months into the project — growing it to 60% of the codebase without slowing feature delivery. Separately, as Senior Developer, I built the Givewith Matchmaking API from scratch with Flask and MongoDB, designing the CRUD architecture, an auto-tagging vocabulary system, program scoring engines, and a CSV onboarding pipeline so non-technical teams could bulk-load content.
