Understand the problem.
Follow it through.

01

Start with the task.

I work out what someone needs to do, then shape the screens and interactions around that task.

Interface design / React / Next.js
02

Follow the data.

I trace what an interface needs back through its services and storage, including what happens when something fails.

NestJS / PostgreSQL / AWS
03

Stay through delivery.

I test the working product, document the choices, and maintain the systems I help ship.

Browser testing / Delivery / Reliability

I like the moment a complicated problem starts to make sense. Then I like making that understanding useful to someone else.
