Learning in public

Eight-week, internals-first course with weekly assignments, lab experiments on a local Postgres 18 container, and notes written in my own words.

One evolving pipeline (order events → validated → priced → customer totals, plus a dead-letter topic) built from scratch with rdkafka, growing through nine phases of concept, build, experiment and mastery check.

From deploying containers by hand to provisioning networks, compute and pipelines from scratch, with AWS and Kubernetes certifications as checkpoints.
