Rockstar🎓
Top SchoolMichal Grno is a data-driven marketing leader and former analyst with 13 years of experience translating applied mathematics and engineering rigor into product and growth outcomes at Pixel Federation. He progressed from game analyst and senior data analyst to Head of Marketing, blending analytics, mobile marketing, and product marketing to steer strategy and measurement across live games. Michal pairs hands-on technical contributions—TypeScript type definitions for DefinitelyTyped and performance/security fixes in prominent open-source projects like mathjs and filtrex—with cross-functional leadership. His background includes applied math masters work and early roles in banking BI and Google data collection, giving him a rare mix of quantitative depth and operational experience. Based in Bratislava, he’s equally comfortable optimizing complex numerical algorithms as he is designing experiments that move KPIs. An advocate for accessibility and empowerment (as hinted in his GitHub bio), he channels technical craft into practical, team-facing solutions.
