About Valeriya

Fullstack Java / Spring Boot & React Developer, I help companies design and develop robust, secure, and maintainable web applications.

Currently in a work-study program within a large IT department, I am working on an internal reservation tool with a REST architecture (Spring Boot, JPA, MySQL), with particular attention to code quality, security, and architectural structure.

How I can help you:

Development of REST APIs in Java / Spring Boot
Design and modeling of databases
Implementation of clear and maintainable business rules
Front-end integration (Angular / responsive interfaces)
Bug fixing and refactoring of existing code
Implementation of best practices (SOLID, clean architecture)

I am particularly attentive to code readability, business logic, and the stability of delivered features. My goal is not just to "make it work," but to build scalable solutions that are understandable by the entire team.

Types of projects I handle:

Internal company applications
Technical MVPs
Backend APIs
Improvement or stabilization of existing projects
Short optimization or correction missions
Rigorous, structured, and solution-oriented, I integrate easily into a team or can work independently on a defined scope.
