Places I've Worked At
Co-Founder & CTO
@ UpSpeech2024 – Present
Co-founded a speech therapy platform for clinics that treat stuttering. I built the Rails API, the React web app and the React Native app, including multi-tenant accounts, session management, patient progress tracking and deployment. Working with Claude Code, I've merged over 2,700 pull requests across them since September 2025. As CTO I own the architecture and product direction, and I work with our AI lead on the transcription and report-writing service.

Full-Stack Engineer
@ Pixelmatters2025 – 2026
Placed with UJET.cx, a cloud contact center platform, building features in Ruby on Rails and Angular. I got the end-to-end tests running in local development, so the team could catch integration bugs before CI, and helped new engineers get their setup working. I led the backend of the Deflection Audio project and mentored a teammate through their first feature. I also brought AI tooling to the team, first Augment Code and then my own Claude Code skills for shipping and code review, which colleagues started using. Promoted to senior (L3) in May 2026.

@ Medihive2022 – 2025
Worked mostly in Ruby on Rails on a cross-functional team. I built internal tools, including the admin and doctor panels, and features on the client-facing site in ERB and some React. Over time I took on whole features from start to production, and the company promoted me to senior developer.

Worked fully remote in Ruby on Rails on a cross-functional team. Each client ran a different Ruby and Rails version, and the job was finding the fix that fit their budget. I upgraded several apps from Rails 5 to Rails 6.
