More than 18 years of experience in developing software for accounting, trading, banking, and finance domains include over 5 years using Java technologies. Skilled in using Spring Boot, Hibernate, Postgres, JUnit, Mockito, and other frameworks and tools. Proficient in applying microservice patterns such as circuit breaker, API gateway, and event-driven architecture.I would like to share my high professional skills that can make a significant contribution to your company. My strengths as an employee include the ability to help the business find bottlenecks in the development and testing processes, as well as efficiently deliver code to a production environment. I actively apply Test-Driven Development (TTD) methodologies to improve the speed and quality of development, and combine various testing techniques in different environments. Additionally, I have skills to assist analysts in staying focused on delivering tasks for important functions.In my previous role as part of a Russian-Indian team, I was involved in creating several microservices from scratch, initially functioning as modules of a single monolith. In my area of responsibility, I was tasked with designing the composition and structure of modules, writing code, and developing automated tests. During the initial stages, I utilized a code-first strategy to reduce the risks associated with designing based on mental models and to expedite the development process. I developed mechanisms for obtaining and processing payment information through Drools, and sending status updates at various stages. I implemented balance calculation in two ways: classic and hierarchical, in accordance with Indian accounting practices.
