What People Say

Thomas is a real pro. He understands the complexities of HTML/CSS and programming, and did an absolutely wonderful job working through the project. Super experienced, communicative, and professional, with technical prowess that many developers lack. I'd recommend him to anyone -- he'll be a true asset on your team.
Building Block Quest AI Project
Tom was one of our strongest engineers. He led critical integrations across our platform, consistently delivered clean code under tight deadlines, and mentored junior developers along the way. His ability to work across the full stack -- C# backend services, frontend dashboards, DevOps pipelines -- made him invaluable to the team.
Power House Marketing Platform
Tom built the backbone of our inventory platform -- syncing Shopify, Square, and PostgreSQL in real time. He took full ownership of the architecture and made it bulletproof. Three years later, his code is still running in production without a single issue.
Grails SF Enterprise Integrations
Very strong coder. Professional, exceeded expectations, and delivered ahead of schedule -- even worked with me on weekends to hit our launch date. Highly recommended.
Dental Implant Machine Marketing Automation
Tom delivered 17 interactive prototypes that exceeded our expectations. WCAG compliant, fully responsive, and polished to a level that our stakeholders mistook for the finished product. Outstanding attention to detail and deep understanding of healthcare UX requirements.
Enterprise EHR Client UX Prototyping
We really enjoyed working with Tom. He picked up the Electron codebase quickly, resolved issues faster than expected, and communicated clearly throughout the engagement. Would happily work with him again.
BWLabs Glacier Chat -- Desktop App
Hired Tom for a Rails project and he delivered a clean, well-tested codebase ahead of schedule. Great communication, no hand-holding required. Exactly the kind of developer you want on a project.
Nub Theory Upwork Client
Thomas was excellent to work with. Fast turnaround, reliable, and professional throughout. He took the time to understand what we needed and delivered exactly that -- no back and forth, just clean results.

Outside the Code

Outdoor Sports

Hiking, cycling, and skiing across the Pacific Northwest. The mountains are a good reset.

Music

Guitar and bass. It's the most reliable way to think about something other than code.

Learning

Science, history, and philosophy. Always reading something that has nothing to do with software.
