Rockstar🎓
Top SchoolPeter Hozák is a versatile research engineer with 14+ years of hands-on experience across web development, data migration and analysis, testing, and business analysis, currently focusing on AI safety evaluation infrastructure. He excels in front-end engineering with a strong preference for React and has migrated legacy AngularJS/class-based React apps to modern stacks while applying SQL, Python (Pandas), and Excel mastery to real-world data problems. His background spans regulated healthcare and clinical sample management at MSD to improving test coverage and frontend reliability in open-source projects like HospitalRun. Peter combines rigorous testing and prototyping skills with practical tooling—optimising automated tests and building internal JS/Excel utilities—to make complex systems auditable and maintainable. Comfortable switching between low-level query work (SUM OVER, INDEX/MATCH) and interactive data exploration, he is also an avid problem solver with a taste for thought experiments, as hinted by his Newcomb's Problem quip. Based in Prague, he brings a pragmatic curiosity and quick learning curve to interdisciplinary engineering and research teams.
