What I'm looking for

I'm open to long-term product roles through Employer of Record (EOR) or Ukrainian B2B/FOP after setup.

At EPAM Systems, I deliver data-heavy enterprise workflows and modernize React interfaces. I’ve migrated a JavaScript component surface from PropTypes to TypeScript and refreshed tests toward React Testing Library.

For a finance-oriented workflow product, I built frontend business logic and worked with backend engineers to reduce API calls and provide frontend-ready data structures. I’ve also partnered with design on feasible UX improvements and created reusable interface components.

I built Foghorn Storefront & Admin Platform as a personal portfolio project and sole product engineer. It brings together a Next.js storefront and a separate AdminJS operations runtime, with a shared Prisma/PostgreSQL data model.

I added automated quality gates, deployment hooks, and post-deploy smoke checks to the project. My approach separates server state from local UI state and makes complex workflows accessible, testable, and ready for release.
