Senior software engineer and DevOps specialist, 9+ years, from embedded firmware to globally distributed HA cloud systems. A lot of my work is site reliability: keeping services up, defining infrastructure as code, and building the monitoring and alerting to catch problems early. The rest is CI/CD, reproducible builds and developer tooling. Boring in a good way. When that layer works, product teams get more time for actual product.
