Sebastian Tommasi

Software engineer in Redmond, Washington who turns ambiguous problems into dependable, usable products.

I work across frontend, backend, data, APIs, authentication, and deployment. My projects span product workflows, external-service integrations, maps and geospatial data, role-aware applications, reliability, testing, and turning a rough idea into software people can actually use.

What I build

  • Stafr — Contributed provider integrations, OAuth lifecycle and recovery flows, messaging and approval workflows, configuration UI, and end-to-end debugging for an AI operations platform.
  • Bike2Beans — Full-stack cycling route planner built with ASP.NET Core, C#, React/TypeScript, MongoDB, Firebase, Google Places, and Mapbox. Includes 38 passing automated tests.
  • Relay — Workflow workspace for connecting integration evidence, engineering context, and clear next actions across a complex investigation.
  • Canvas LMS — Collaborative full-stack learning-management system with React, Express, MongoDB, session-based access, and role-aware course and quiz workflows.

Tools and technologies

I’m open to early-career roles where I can build, ship, learn quickly, and take meaningful ownership across the product and engineering lifecycle.
