What I'm looking for

I'm looking to build high-traffic, data-driven products end to end, especially AI-powered and subscription experiences where I can improve performance, reliability, and delivery speed.

At GlamAI, I build AI-powered photo and video editing experiences used daily by thousands of subscribers. I designed billing and entitlement synchronization across Stripe, Airwallex, and Adapty, and migrated backend services to Kubernetes on AWS with zero-downtime CI/CD that reduced releases to around 10 minutes.

Previously at Onfy, I built a Node.js/NestJS event-analytics service processing about 1B records per day, along with A/B testing, feature-flag, and Stripe billing-data search infrastructure. I focus on end-to-end delivery, from React and Next.js interfaces to scalable backend services.

At EPAM, I improved React performance for a multi-million-user application, reducing initial load time by 300 ms, while contributing to accessible UI systems and shared component libraries.
