Top SchoolOleksandr Kobelyuk is a Software Development Engineer based in Portugal with 8 years of hands-on experience building and maintaining production systems. He holds a Bachelor's and Master’s in Telecommunications and Computer Engineering from ISCTE and currently contributes to Nokia after a brief tenure at Infinera. His background includes optimizing web service performance at Aptoide (halving payment flow load times) and running a Discord bot service that supported over 25,000 daily users, demonstrating both performance tuning and operational ownership. Comfortable across backend development and database maintenance, he brings practical experience scaling services for real user demand.
