Profile

Software engineer focused on building things that are fast, easy to use, and reliably available — web engineering, performant Java services, and accessibility, with platform engineering, DevOps and systems languages (Rust, Zig, Go) picked up alongside. A few years (2015–2018) were spent on mobile. Writing about what I'm learning, in public.

Core competencies

Web engineering current focus

Front-ends and services built to be fast, easy to use, and reliably available — not just functionally correct.

Java & performance current focus

Building applications on the JVM engineered to stay fast and stay up under real load.

Accessibility current focus

Making interfaces that work as well by keyboard and screen reader as they do by mouse — not just passing an automated check.

Platform & DevOps learning in public

CI/CD, infrastructure as code, and observability — the practices that keep something fast and working from quietly stopping being either.

Systems languages learning in public

Rust, Zig and Go — going a level lower than the web stack to understand what it's built on top of.

Mobile 2015–2018

Native and cross-platform applications, with the usual trade-offs around offline state, background work and release cadence.

Experience

12 years building fast, usable, reliably available software — web engineering, Java, accessibility and platform work, with a few years (2015–2018) on mobile. A detailed role history is available on request — or take the writing and the projects as the working sample.
