My journey in programming spans from Java 8 to the latest version, Java 17.
In the database realm, I've navigated both relational (Postgres, MySql, SqlServer) and non-relational databases (Redis, MongoDB, Cassandra, RocksDB).
My tech toolkit includes Spring Boot, Spring Framework (Security, Data, MVC, Cloud, Config, Eureka, Feign), Hibernate, Jooq, Flyway, Liquibase, Mockito, and JUnit, etc.
On the DevOps front, I have experience with Docker, Rancher, and Kubernetes, Git, CodeCommit, and implemented CI/CD pipelines with CodeBuild and Jenkins.
My current project, which relies on event-based communication, includes 50+ microservices. During the last year, we've migrated all of the infrastructure from on-premises to AWS. My team is on the front lines of delivering new features to the customers. The last and biggest task we've implemented so far was to create a bunch of services (based on the SAGA approach) that communicate using the SNS/SQS to track some order states.
At this point, we're hight involved in the development of the service responsible for tracking shipments.
In my role, I handle various key responsibilities:
1) Developing Features: I create new features and enhance existing ones, actively contributing to the software's evolution.
2) Ensuring Code Quality: I make sure my code is reliable by thoroughly testing it with unit and integration tests.
3) Research and Innovation: I stay updated on new approaches and technologies, bringing fresh ideas to the team.
4) Collaborative Planning and Design: I actively participate in discussions and planning sessions, offering insights to shape new features in line with project goals.
5) Mentorship: I act as a mentor, sharing my knowledge and supporting the professional growth of team members.
In addition to my primary responsibilities, I also play a crucial role in the recruitment process by conducting interviews for potential team members.
My current goal is to continue my growth in the DevOps, and DevSecOps direction.
