Tutorial-style posts on data/software engineering and GenAI.

I'm Andreas, a Lead Data Engineer at Altruistiq. I build a wide variety of features on AWS and Snowflake, handling both event-based and batch-based workloads. An increasing focus of mine has been production AI systems on AWS Bedrock with pydantic-ai, and here I write up the patterns, gotchas, and architecture decisions worth keeping. Every post links to runnable code. I try to build things up from the basics and make sure everything is runnable with an AWS account and some Terraform.
