Payroll Lead @ Talenox

Software is easy when everything behaves as expected. But when it doesn't, it's a different story. I love the challenge of debugging complex systems and finding the root cause of bugs. Specializing in compliance-critical engineering - from statutory calculations to multi-bank disbursement pipelines. I'm currently leading the payroll team at Talenox building systems and integrations that need to work - not just most of the time, but every time.

Archery

Target archery with recurve bow. A discipline of breath control, focus, and stillness under pressure - the antidote to a noisy code review.

Freestyle and aggressive inline skating. The closest thing to flying on pavement - all about flow, control, and the freedom of movement.

Gliding on ice with a focus on balance and control. Less forgiving than pavement - small mistakes are immediately felt, much like bugs in production.
