Summary
👤
Senior🎓
Top SchoolJonasz Potoniec is a frontend TypeScript developer with eight years in software and over two years of commercial React experience, known for shipping polished user interfaces and improving UX and performance across healthcare web apps. As the primary frontend engineer at HTD Health he led feature work, mentored interns, and used React Query, Redux Toolkit, Material UI and Styled Components to solve complex state and UI challenges within Scrum Nexus teams. He combines a strong CSS intuition with a tinkerer’s mindset—building browser extensions and even an ergonomic mechanical keyboard from scratch—which shows up in careful, user-focused interfaces. A hackathon medalist (2nd place, EEIA Jam 2021), he thrives in time-pressured problem solving and client-facing demo contexts, bridging technical delivery with clear communication. Based in Łódź, Poland, he brings practical product lifecycle experience from internships to production systems and enjoys exploring new frontend patterns beyond standard stacks.
