What I'm looking for

I’m looking for a backend role where I can build and optimize secure microservices and REST APIs, focusing on authentication, performance, and reliable production systems in a collaborative remote Agile team.

I’m a Backend Software Engineer with production experience designing, developing, and maintaining scalable server-side applications, RESTful APIs, and databases that power high-performance systems. In my current remote role at DataArt, I build cloud-oriented microservices and backend services for financial platforms, optimize data access and database queries, and refactor production components to improve reliability and maintainability.

I focus on authentication, security, and API performance optimization, and I’ve delivered concrete impact—reducing AWS Lambda cold-start time by up to 90% by migrating JVM workloads to GraalVM native images. Previously at PLEXSUPPLY, I developed Java/Spring Boot microservices for an internal marketplace, implementing RESTful APIs, asynchronous communication with Apache Kafka, and Spring Security-driven authentication and authorization while deploying with Docker and Kubernetes in Agile/Scrum workflows.
