Profile
Senior backend engineer specialising in distributed systems and performance-critical software. I design and run event-driven, serverless systems on AWS that handle millions of events a day with strong consistency and high throughput, after earlier years on payment platforms and logistics systems. I work mainly in Python and .NET, with a Java background, and care about reliable architecture, observability and clear technical decisions.
