At present, I am engaged in the development of a risk management system. This system is a monolithic Spring application deployed across a cluster of servers, leveraging the capabilities of Oracle Coherence cache and Akka. My responsibilities include improving of CI/CD processes, analyzing and implementing new features, managing releases, and providing production support for SL3.

I worked on faulty-ATM-operations settlement sytem, which was initally developed as monolith application using Java EE and was running on IBM WebSphere. For a half of my first working year the main tasks included developing on new features, units, fixing bugs, writing docs, using Java EE stack, Oracle, IBM MQ, Then we started to transform our application to microservice architecture on kubernetes-based platform RedHat Openshift with monitoring based on prometheus, grafana and ELK stack. I was developing microservices from scratch and enhancing existing ones. Spring Boot and Kafka with PostgreSQL were the main techologies used in developing microservices, but such techonoliges as GRPC, Rest, Akka, Apache Ignite were also commonly used.

The project I was working on is the same as in UNIS Labs. I've just moved from one contractor to another.I was developing a system performing an electronic document flow for Russian Railways - main railroad company in Russia. System was based on IBM Integration Bus (now known as IBM App Connect Enterprise) stack including IBM DB2 and IBM MQ. System worked on IBM mainframe with z/OS. My responsibilites included java, javascript, sql developing, some administration of z/OS, IBM MQ, communicating with stakeholders, presenting demos and supporting production.
