At Innowise, I designed Node.js and Go microservices serving 100M+ API calls per month and built AI infrastructure that lets non-technical teams create and deploy mini-apps through self-service tooling. I also re-architected high-load platform pages, cutting load times by 80% and database queries by 75%.
At NDA, I owned the design and evolution of payment infrastructure spanning 200+ provider integrations, and built a multi-currency payment system. I led a four-engineer integration team and built a recommendation system based on country, category, and provider.
Earlier, at Ramp Network, I developed backend services for a high-traffic e-commerce platform and helped expand it to five additional countries. At EPAM, I developed Python and Node services for a digital ecosystem serving 350M+ players, integrated third-party services, and contributed to test suites and GitLab CI/CD pipelines.
