Rockstar🎓
Top SchoolTomasz Gieniusz is a Senior Staff Software Engineer based in Melbourne with over 13 years building backend systems, DevOps pipelines, and large-scale event-driven architectures. He has deep AWS and Terraform expertise, designing secure, scalable services that handle complex distributed systems challenges. At SEEK Pass he progressed through engineering and staff roles, consistently focusing on reliability, automation, and clear communication of technical concepts to non-technical stakeholders. His security background is practical and hands-on—he’s active in CTFs and skilled in exploitation, privilege escalation, reverse engineering, and cryptography—bringing an attacker’s mindset to defensive design. An avid competitive programmer, he couples algorithmic rigor with pragmatic engineering, and his early open-source work creating a git statistics generator reflects a knack for defining solid project structure and core tooling.
