What I'm looking for

I’m looking for a team where I can own backend and microservice architecture end to end, modernize systems on AWS, automate CI/CD, and mentor engineers—while partnering with Product, DevOps, and QA to deliver reliable, high-performance services.

I’m a Lead Software Engineer with 7+ years designing and shipping enterprise backend systems in Java and Spring Boot. I build microservices around clear domain boundaries using layered architecture, DDD, and event-driven integration across relational and NoSQL data stores.

I own technical initiatives end to end—architecture decisions, code review, mentoring, CI/CD automation, and production performance. At EPAM Systems, I led the full delivery lifecycle of services handling over 1M requests per day, modernizing legacy platforms onto AWS with serverless and managed services.

I’ve driven measurable outcomes through smarter delivery and system design. I modernized with Node.js and React alongside the Java core, improved scalability, and cut delivery time for new features by ~30%, while CI/CD automation reduced release cycles from days to under an hour.

Previously, I sustained 99.9% uptime in production by modelling domains and shifting from synchronous coupling to event-driven messaging over Kafka and ActiveMQ. I’ve also delivered Spring Boot and Micronaut backends as a freelancer, advising clients on pragmatic, cost-effective technical solutions.
