United StatesSenior Backend Engineer at Comtek
About
I'm building and maintaining dealer- and customer-hierarchy systems at Comtek, where I cut a heavily used API from 300ms to 150ms by improving queries, metrics, and retry handling.
Across payments and banking, I've delivered card transfers, billing, MFA-protected transactions, reporting, and booking-platform payment services. At Toptal, I removed a 20-second processing delay and improved high-traffic application performance by around 80%.
I've led a five-person engineering team at EPAM while staying hands-on with planning, code reviews, mentoring, and delivery. My work spans Java, Spring, Python, AWS, microservices, databases, messaging, CI/CD, and observability.
I also build products end to end, including Nazar, SiteFlow, and Yangi Davr—owning backend services, data pipelines, AWS infrastructure, CI/CD, and deployment.
Experience
