Almere Tech #40 - Abhishek Jain

"We built a payment platform without a database"
Can you process payments entirely through Kafka, without databases and without services calling each other directly?
At Almere Tech Meetup #40, Abhishek Jain (Super, Booking, Amazon) shares how his team rebuilt a payment platform around Apache Kafka. Learn how Kafka partition ordering replaces database locks, how services rebuild state directly from event streams, and what happens when this architecture meets the reality of production. Expect practical lessons, honest failures, and insights from a system that is running in production today.

We'll also close the evening with a short update from Sandra van Beers, who will share the plans for ALLUMINOUS 2026, Almere's light art festival. She will present several opportunities where the local tech community can contribute and help bring this unique event to life.

The program is as follows:

• 17.30 Door open, welcome drinks
• 18.00 Word of welcome by Stijn Sprenkels, serving of snacks
• 18.15 Lightning talk of Abhishek Jain
• 18.45 Q&A, discussion
• 19.15 ALLUMINOUS 2026 update by Sandra van Beers
• 19:30 Networking drinks
• 20.00 End

Almere Tech is the meetup for the larger Almere area for startups, entrepreneurs, developers and those interested to discuss new technology. Everybody can join in for a drink and hopefully interesting and inspiring conversations.

Hope to see you all again soon!
