Software developer · Zavidovići, Bosnia & Herzegovina
React, Next.js and TypeScript. I build complete products: client websites, a live community site, and a media app of my own, each designed and built solo.

Real work
A client, a community, and a tool I use every day. Built solo, deployed, and maintained.
Production website for an independent heat pump service in Switzerland. I handled the whole project solo, from concept to launch. Multi page, German language, SEO metadata, optimized images, cookie consent.
Official website of my local community association: the annual memorial football tournament, a photo gallery, tradition, local history and the memorial dedicated to the fallen defenders of the country. I designed and built it, and I keep it live and maintained for the community.
Media downloader for YouTube, SoundCloud and Vimeo that can grab a whole playlist from a single URL. Server side download pipeline, so for now it runs locally.
