At Aetsoft, I architected React and Next.js applications, integrated third-party services including Stripe, and built and tested React Native components. I also improved initial app load time by 50% and achieved 85% test coverage across core modules.

At iTechArt Group, I led a six-person team as TeamLead and designed custom back-office features. Earlier there, I developed NestJS and PostgreSQL APIs and contributed to an offline-capable React Native application.

At SkillCrucial.com, I virtualized a data grid to handle 10,000+ rows and reduced server response times for training modules by about 35%. As a freelance Frontend developer, I created JavaScript interfaces and resolved more than 50 production issues.
