Spendesk
Spend management · Berlin · Feb 2023 — Nov 2025
Spendesk is a spend management platform for company finance and accounting teams. I owned the wire transfer system — the part that actually moves the money — first for the UK market, then across a shifting set of banking partners in the EU.

A wire transfer system for the UK
Planned and executed end to end, from design through rollout. It ran at 99.9% uptime, and the transactions it replaced stopped being something customers had to chase.
-
Banking partner migrations
Moved multiple banking partners across EU and UK markets onto the existing wire transfer infrastructure, without interrupting the payments already running through it.
-
Invoice and expense management
Core features on the systems finance teams open every day.

Load testing, as a practice
Led the initiative to introduce load testing strategies across the organisation rather than leaving it as one team's habit. Knowing what breaks first is cheaper to learn on purpose.
-
Invoicing that earns
Core invoicing features aimed directly at revenue.
Payments are unglamorous until they fail. Most of the engineering here is not the happy path — it is reconciliation, partner-specific edge cases and what the system does at three in the morning when a bank stops answering.
