At Datum, I built an offline-first pre-flight performance calculator for Brazilian general aviation, handling the data model, Node.js API, React Native app, and release. I designed calculations to run on-device and made missing values surface as unknown rather than assumed.
At Rita Data, I was principal engineer for the mobile app of a personal-data platform that grew to over 150,000 users. I built and maintained its data extraction engine, which worked with Google and Facebook export flows, and parsed large archives in chunks to keep memory flat.
At Keystone, I delivered client-facing financial reporting that reconciled figures across five systems, and built a meaning-based consultant search. Across my projects, I’ve also worked on race-safe payment flows, mobile products, and AWS services.
