Three rules I work by.
The tech matters, but how the work gets done matters more. These are the principles behind every project I take on.
Build what matters.
No unnecessary features or needless complexity. Every technical decision serves a clear purpose.
Work as one team.
Clear communication, shared responsibility, and work that fits well with the rest of the product.
Ship with confidence.
Quality is not only about what is checked automatically, but also about attention, experience, and continuing to see the product through the user's eyes.

All work→Sharp tools, kept sharp.
How I work.
Solo or embedded in your team — I adapt to what the project needs. For larger opportunities I can assemble a full squad of developers, designers, and project managers.
Discover
Scope, constraints, success criteria — mapped out together before any code is written.
Design
Architecture and interfaces, tightly aligned. You see what you're getting before development starts.
Build
Typed, tested, deployed continuously. Live previews so you can follow along.
Ship
From launch to real-world use, with room to learn and make focused improvements.
