Top SchoolMarius O is a Frontend Developer with 13 years of professional experience and 5+ years focused on building intuitive, high-quality user interfaces across web and mobile. He currently drives front-end work at StructureFlow and has shipped full-stack products from scratch—including an e-commerce platform with secure payments (Stripe) and Auth0 authentication and a React Native touring app with backend systems and in-game algorithms. Comfortable across TypeScript, React, Node.js and styled components, he emphasizes readable, testable, and maintainable code, and has a track record of improving legacy codebases and adding robust test suites. Uncommonly for a front-end specialist, he contributes to the pandas open-source project on data-visualization and CSV handling, showing aptitude for data tooling and cross-domain problem solving. His background in finance and prior leadership roles in recruitment/operations give him strong product empathy and stakeholder collaboration skills. Based in Stony Stratford, UK, Marius blends hands-on engineering with an operator’s mindset to deliver useful, scalable experiences.
