What I'm looking for

I'm open to backend opportunities across different business domains, where I can build and improve systems for billing, payments, subscriptions, marketplaces, e-commerce, or internal platforms.

I've built backend systems for MacPaw billing, SignNow payment and subscription workflows, Rozetka marketplace services, and internal platforms. My work includes REST APIs, complex billing logic, third-party integrations, and production improvements across PHP and Go services.

At SignNow, I progressed from Middle to Senior Backend Engineer while refactoring fragile billing components, expanding automated testing, and reducing manual handling of subscription edge cases. I'm open to backend opportunities across different business domains.
