About

My name is David Yanacek and I'm a Software Engineer working on Agentic AI at AWS.

Over the years I've worked on a variety of teams at Amazon, including writing the web service client and server framework that Amazon is built on, automating website operations (host failure, scaling forecasting), Amazon DynamoDB (Amazon Web Services' high performance, ultra low latency, managed, NoSQL database service), AWS IoT (building a scalable PubSub message broker for enormous numbers of devices), AWS Lambda (serverless compute), Amazon API Gateway (serverless API), and Amazon CloudWatch (observability).

I started this blog in 2026, but backfilled it with various public things I've talked about. Most of my writing and blogging is company-internal, so if you want to read more, you'll have to come work with me!

This is my personal blog. Opinions are my own.
