What I'm looking for

I'm open to remote work where I can build secure, scalable Java and Spring Boot platforms, deliver API-driven product features, mentor engineers, and improve delivery through AI-assisted development.

At Grid Dynamics, I build the mobile order experience layer for Macy's and Bloomingdale's, powering bag, checkout, payments and order placement for millions of mobile users. I also own the shared platform foundation for caching, security, resilience, observability and service integration.

I've built Spring Boot security starters that reject SQL injection and XSS, support production rule updates without redeployment, and provide shared contracts for resource-ownership enforcement. Across GCP and AWS, I deliver event-driven pipelines, search APIs, REST and GraphQL services, and customer-facing commerce features from API contract through rollout.

I've also delivered Java and React systems for HqO, Potty Plant and Zimbocash, and I mentor Java engineers through EPAM Java RD School and Grid School. I enjoy strengthening engineering workflows through code review, technical specifications and AI-assisted development with Claude Code.
