Summary
👤
Senior🎓
Top SchoolZenios Zeniou is a software engineer based in Stockholm with nine years of experience building and testing robust systems, currently developing games and tools at Embark Studios. He has strong backend and QA chops from contributions to IOHK’s Jormungandr privacy-voting blockchain—writing integration and functional tests and improving core Rust code—alongside engineering roles at Apple and Intel. A self-described polyglot who favors Rust, he enjoys experimenting with new languages and frameworks and has a pragmatic "make stuff" mentality evident in both production and open-source work. His background in electrical and computer engineering and an early career pivot through data science give him a systems-level perspective that helps bridge low-level performance concerns with high-quality test automation.
