Summary
👤
Senior🎓
Top SchoolAnton Vasiljev is a seasoned technology leader and CTO based in Poland with 18 years of hands-on experience building full‑stack web platforms, data pipelines, and developer tools. He blends managerial responsibilities—hiring, process improvement, and firefighting—with deep engineering work across Node.js, Ruby, Python, JavaScript and cloud platforms like GCP and Azure. Anton has led teams from small cores to 15-person squads, shipped ETL and BigQuery/DataFlow pipelines, and driven DevOps and architecture decisions in startups and scaleups. An active open-source contributor, he has strengthened enterprise SSO projects (rubycas server/client) with i18n and authentication integrations and added developer tooling like CTags support for the Redcar editor. He’s equally comfortable refactoring backend authentication logic as he is designing analytics workflows, a versatility rooted in long experience from founder roles to corporate engineering. That mix of product-driven engineering and pragmatic leadership makes him a CTO who still writes code to solve real operational problems.
