Rockstar🎓
Top SchoolMichal Vrtiak is a Staff Software Engineer and tech lead based in Brno with 13 years of experience designing and shipping JVM-based backend systems and architectures. He has led org-level architecture and microservices adoption at Help Scout, driving major migrations (Mailbox to Inbox) that moved ~80,000 users while preserving backend performance and shipping features like Snooze & Send Later and AI-powered support. At Sourcegraph he worked on observability and in-app audit logging, contributing backend and DevOps fixes to a widely used code search and AI tooling repo. Comfortable across dev, ops, and security concerns, he pairs hands-on problem solving—deadlock fixes, API pagination handling, and audit-log migrations—with strategic system vision and cross-team enablement. Notably, he blends deep JVM/ Kotlin expertise with practical contract-testing and logging/observability work that keeps distributed services resilient in production.
