Angular applications for enterprise clients — and the tooling that keeps them fast.

Frontend engineer building Angular applications for enterprise clients — from the first line through to production, and keeping the older ones running. I also look after what surrounds them: tests, CI/CD, automated releases and error monitoring, with Java and Spring Boot when the backend needs a hand.

Outside work I build tools I actually use: Loadline tells you what each screen of a web app really downloads, so you can fix it before it ships, and Waypack is an Android app for packing by day, by bag and by person.

Bundle analysers report what each chunk weighs. Loadline reports what each screen costs: it walks the import graph of your build, separates the bootstrap everyone downloads from the code a single route adds, and counts how many round trips a screen takes to arrive.

One tool, two front doors — a single HTML page that runs offline in your browser, and a command for your pipeline. Same code, same numbers. Zero runtime dependencies, nothing uploaded, nothing fetched.

A packing and trip organizer: what to bring, by day, by bag and by person. Two checks instead of one — prepared and actually in the bag — so what you found but left on the table still shows up before you leave.

The domain is plain Kotlin Multiplatform, so it can travel to iOS without a rewrite, and it ships in four languages from the first release.

Testing it, or found a bug? Come say hi on Discord.
