Java / Spring backend engineer Biel/Bienne, Switzerland · Swiss B permit, unrestricted labour-market access · open to work
Two years of professional experience in systems where being wrong is expensive. I delivered the first cross-border rollout of an investment bank's money-market module, across two country units and two regulatory contexts, and built a legal research platform together with practising lawyers, turning regulated procedural rules into correct software.
I like the work most developers avoid: grown systems, domain experts who don't think in tickets, and requirements that only make sense once you understand the regulation behind them.
