Full-stack developer building AI-powered products.
Shipping software professionally since 2017, from Cluj-Napoca, Romania, across multinationals, startups, and midsize companies. Currently at InnovatorSpark, turning ideas into working products (designed, built, tested, deployed, and operated end to end) and putting new technology to work where it creates the most value for users and the business.
