Staff Software Engineer at Snyk, based in Lisbon. I build platforms that other engineers choose to use, and I build security in rather than bolting it on.
- Now: principal architect of Snyk's AI-powered penetration testing service: autonomous agents running in hardened gVisor sandboxes.
- Before: principal architect and product owner of a bank's internal developer platform at CECG, which grew from one tenant to ~50 teams; principal engineer on a major UK media company's CRM, moving it to CI/CD, automated tests and trunk-based development; and at Sky, helping scale a multi-region Kubernetes platform to 60M concurrent users.
- Writing: MVP Security for a Bank Developer Platform · Security for a Large International Media Provider's IDP
- Teaching: Kalschatzi's Learning Platform: free mentoring and course material for people starting in tech.
- Stack: Go, Rust, Python, Java · Kubernetes · AWS, GCP · PostgreSQL, Redis, Kafka
