N26

Four years shaping the technical core of Europe’s most-funded neobank. As Principal Engineer: delivered the architectural vision for payments (bank and peer-to-peer transfers) and customer acquisition; led the overhaul of financial crime prevention — replaced a static rule engine spread across microservices with a real-time Apache Flink streaming system in under six months. Before that, as Tech Lead: architected the fee charging platform that became standard infrastructure embedded in N26’s ledger APIs across Europe.
