Over three months, Andrii Didvar developed and enhanced backend systems for the UA-1378-TAQC/codeWars1378 and GreenCity repositories, focusing on robust API and data processing solutions. He established a modular tasks framework with interface-driven design in Java, introducing utilities for volume calculations, string manipulation, and numeric analytics, while improving build stability and test coverage. In GreenCity, he delivered new event management API endpoints and implemented JSON schema validation with DTO-driven contracts, using Python and Pytest for comprehensive testing. His work emphasized maintainable architecture, reliable data validation, and test-driven development, resulting in scalable, well-organized codebases that support future feature growth.

June 2025 — Focused on strengthening event data integrity in GreenCity. Delivered Event Update API Data Validation and DTOs with a JSON schema, and updated tests for event retrieval and update endpoints to exercise the new validation path. Fixed related tests to align with the new contracts, improving reliability and maintainability. This work reduces invalid event updates, simplifies future validation enhancements, and enhances vendor/client integration confidence.
