Real-Time Data Processing

A 12-lesson course that starts with a single Postgres node and ends with a full streaming pipeline. Each lesson runs three hours — roughly one hour of theory and two hours of building, benchmarking, and breaking things.

Enablement & workshops

At Santander I taught 300+ employees across 6 bank areas on agent harnesses (ChatGPT, Copilot, Claude, Windsurf, Devin, Cortex), and shipped 1 MCP + 1 skill now used by 50+ engineers.
