Zach
Matcham.

I build the software, and the systems it runs on.

software developernetwork engineersystem architect

Software Engineer at Tranquil IT, based in Hertfordshire. A computer science graduate who's just as comfortable shipping a Vue front-end as wiring up the InfluxDB pipeline and the box it lives on.

// · about

I'm a developer who never stops at the edge of the codebase.

My background runs the full width of computer science — full-stack development, network engineering, algorithms, and system architecture — so I tend to see a product and its infrastructure as one thing rather than two. That perspective comes from my years of experience across almost every aspect of computing.

Day to day I'm a Software Engineer at Tranquil IT. Before I wrote software for a living, I spent years in retail and hospitality; the kind of customer-facing work that teaches you to stay calm, communicate clearly and be the person others can rely on when it's busy.

Outside the day job you'll find me deep in side projects; mobile-network mapping tools, my homelab, or maybe even doing a bit of DJing. I like understanding things all the way down and solving interesting problems.
