Talks

Booking

Everything a programme committee needs to list a session: the four subjects I speak on, the formats I have done them in, and a bio you can paste.

What I speak on

• Stream processing and event-driven architecture

  Apache Flink and Kafka in production — stateful jobs, the outbox pattern, and what it takes to operate them inside a licensed bank.

• Fraud prevention in regulated fintech

  Replacing a static rule engine with a real-time streaming pipeline at N26, and the latency budget that decision has to fit into.

• Energy infrastructure as an engineering domain

  Swiss local energy communities: metering data on someone else's schedule, allocation on fifteen-minute intervals, and an invoice with legal consequences.

• The shape of an engineering career

  The path to staff and principal level, non-traditional routes into the work, and leading platform teams without becoming a bottleneck.

Formats

• Conference session
• Meetup talk
• Panel
• Community / TEDx talk
