Boris Solos-Senior Software Developer

With my extensive experience as a Java full-stack developer specializing in Spring Boot, REST, microservices, GraphQL, and Docker, I am applying for the advertised position.

Furthermore, I have in-depth knowledge of PostgreSQL, Oracle, nested complex SQL/JQL queries, Git, CI/CD (GitLab, GitHub), Kotlin, Angular, Jira, and Confluence, along with IntelliJ. Among various middleware types, I gained experience with Camunda BPM at a bank.

As a graduate mathematician, I have a clear understanding of the complexity of algorithms, graph theory, simplex methods, logical formulas, geometric mappings, numerical methods, and related topics.

Over the past few years, I have gained valuable experience in various industries, particularly in the areas of logistics (goods flow control, warehouse management, international supply chains, goods transport control) and BTC data management. My work style is strongly influenced by teamwork in agile Scrum teams, working shoulder-to-shoulder with GUI and QA colleagues, where I was actively involved in both the development and testing and integration phases.

My main responsibilities included developing and implementing server-side applications with a focus on REST APIs and deploying them in Docker containers, creating SQL database tables with indexes, ensuring data integrity, and optimal data types. I also worked closely with front-end developers to coordinate requirements, define parameter formats, and optimize the logic of REST data structures. I successfully used Springdoc OpenAPI for documentation and direct testability (JUnit, Mockito) of the interfaces.

In my last position at the startup advaneo GmbH, I was heavily involved in the development of two middleware solutions, TDH and EDC. Both projects reached version 1.0 in January 2025 and were successfully presented to investors and customers.

TDH focused on processing CSV data from various technical sources. This data was then prepared for data analytics using Generative AI in Jupyter Notebooks. Although the AI component played a supporting role, I was able to gain valuable experience in data analysis and its integration into backend systems. EDH uses a variety of Java Security REST APIs from Keycloak/OAuth2 to keep me constantly busy.
