Lendava / Lendva, Slovenia
Summary
🤩
RockstarMatjaž Horvat is a product-focused engineer with 15 years of experience blending front-end development, UX sensibilities, and deep expertise in localization and internationalization. Based in Lendava, Slovenia, he has contributed to high-profile Mozilla projects—such as Firefox Send, Common Voice, Screenshots, and the Pontoon localization platform—improving translations, editor UX, and deployment workflows. He pairs practical full-stack development skills with a specialization in .ftl-based localization, supporting many languages from Slovenian and Esperanto to Chinese and Welsh. Matjaž is comfortable moving between product thinking and hands-on implementation, shipping features that make software usable across linguistic and cultural boundaries. Less obvious: he often focuses on the plumbing that scales localization—file format support, language pack generation, and translation management—so multilingual products stay maintainable as they grow.
