Senior🎓
Top SchoolDennis Tusk is a Senior Software Developer and SysOps specialist based in Gdańsk with 11 years of hands-on experience building backend systems and operating production infrastructure. He blends senior Ruby and DevOps expertise with practical sysadmin instincts, having moved between roles that span startup CTO responsibilities, speech/ML-related development, and scalable backend engineering.
