Summary
🤩
RockstarMatej Bukovinski is a seasoned engineering leader and CTO based in Ljubljana with 16 years of hands-on experience building and advising mobile-first products. He blends executive technology strategy with deep iOS craftsmanship—co-authoring several published apps and driving high-impact improvements to widely used open-source libraries like SDWebImage and MBProgressHUD. As a frequent consultant and current CTO at Nutrient (formerly PSPDFKit), he’s comfortable moving between product, platform, and developer experience, and fixing subtle issues such as threading, decoding performance, and cross-platform compatibility. His work spans UI polish, caching and performance optimizations, and CI/test coverage tooling, reflecting a pragmatic focus on reliability and developer ergonomics. Less obvious: he still contributes code-level refinements that directly improve app UX and maintainability, rather than delegating all technical detail.
