With over eight years of experience as a Java developer and tech lead, I have specialized in designing and implementing robust solutions for various business needs. Currently, I am a Java Tech Lead at LLC “Wezom”, where I manage a team to develop an ERP system using Java 17, Spring Boot, and a range of other technologies. My responsibilities include analyzing requirements, developing technical documentation, task management, and code review. In previous roles at LLC “1648Factory” and LLC “Brightgrove,” I led the development of serverless and microservices-based solutions, implementing new features and architectures using AWS infrastructure and various Java frameworks. Earlier in my career, as a Senior Java Developer at LLC “Customertimes” and LLC “Cogniance,” I focused on building and securing APIs, integrating services, and deploying applications using Docker and CI/CD tools. My background includes a strong emphasis on unit testing with JUnit and Mockito, and extensive experience with Spring frameworks, Kafka for messaging, and PostgreSQL and MongoDB for data storage. With a solid foundation in both backend and frontend technologies, I have consistently delivered high-quality, scalable software solutions. I hold a Master’s degree in Automatic Process Control Systems from the National University of Food Technologies.Tech Stack

Best back-end engineers I've ever worked with...
“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
