NetherlandsWhat I'm looking for
I'm a backend engineer with almost 20 years of experience. I've built systems from scratch, scaled them, and rescued a few that nobody else wanted to touch. One of them now handles over a million bookings a month.
Most of my career has been in PHP and Laravel. Greenfield builds, legacy overhauls, hexagonal refactors, CI/CD, Kafka, the works. The last few years I've also been working in Go, building microservices with proper observability: metrics, tracing, alerts, SLOs.
I spent six years as the (mostly) sole engineer behind a US startup, owning everything from architecture to server ops. I've also led teams, mentored juniors, and written the documentation people actually read.
These days I work independently through Viseu Labs with companies that need senior backend help. Stabilizing a legacy app, building a new service, fixing the delivery pipeline around it. I like problems I can own end to end.
Remote-first, based in the EU.
