delivery profile
Best fit for teams that need a senior engineer who can untangle domain complexity, improve reliability, and keep stakeholder conversations user-focused.

Outcome-driven engineer meets gym rat
$ cat profile.md
For 12+ years, I have built production software across payments, public transport, sustainability, marketing, and operational tooling. I like the middle ground where architecture has to be thoughtful, delivery has to be practical, and the users still need it to work on Monday morning.
Away from the keyboard I live in Kudelstaart with my girlfriend Lara. I enjoy the gym, co-op board games, and just enough The Office to keep my quotes dangerously available.
