Tomas Berg
Tomas moves between data work and backend architecture, which is less of a jump than it sounds: both are mostly about what you do when the volume grows by two orders of magnitude. He teaches with worked examples and back-of-the-envelope numbers, because a design you cannot estimate is a design you cannot defend.
View instructorWhat you'll learn
Assemble the building blocks
Know what load balancers, caches, and queues each solve, and what they cost you.
Scale the data layer
Partition and replicate data, and reason clearly about the consistency you gave up.
Design resilient APIs
Handle retries, idempotency, and rate limiting so failures do not compound.
Estimate capacity
Do the arithmetic that turns a hand-wavy design into a defensible one.
