Backend & API Development:Design of robust APIs and complex business logic with Java and Spring. Also proficient in GraphQL.
Data Management:Modeling and administration of relational (MySQL, PostgreSQL) and non-relational (MongoDB) databases.
DevOps & Tools:Containerization with Docker, continuous integration with Jenkins, version management with Git, and API documentation with Swagger.
My strengths:
Rigor and method:Experience with Agile methodologies (Scrum, Kanban) and design tools (StarUML, Looping).
Passion and awareness:Constant curiosity for new technologies and best development practices.
Communication:Operational English level (C1) for working on international projects.
