Summary
👤
Senior🎓
Top SchoolJuraj Mäsiar is a WebExtensions specialist with 11 years of software development experience, focused on TypeScript, Vue, NestJS and PostgreSQL. Since 2016 he has authored 25+ browser extensions (15+ public) for Firefox, Chrome, Edge, Safari and Thunderbird, accumulating over 50k users and approaching a cumulative audience under one million. He combines frontend polish (Vue/Vuetify, modern JS APIs) with backend discipline (NestJS/Play, PostgreSQL) and a history of building full-stack products from student portals to commercial addons. Comfortable in both solo-authoring projects and team-based backend work (Scala/Play at Accenture), he brings a pragmatic, productivity-driven mindset—he builds tools to make users more efficient. Based in Slovakia, he balances deep browser-extension expertise with practical server-side experience, often leveraging advanced browser APIs like Web Crypto and IndexedDB.
