Andrey Zhelepov developed and enhanced core features for the Ecwid/ecwid-java-api-client repository over a two-month period, focusing on both API functionality and security. He built a modular brand search and retrieval API layer in Java and Kotlin, introducing new methods and data transfer objects while refactoring the codebase for maintainability and standards alignment. Andrey also improved test reliability by stabilizing test data and configuration management. In the following month, he extended data masking to cover sensitive tokens in both key-value and JSON formats, strengthening secure logging practices. His work demonstrated depth in API development, backend engineering, and data security.

January 2025 focused on hardening data security in the Ecwid Java API client by extending data masking to cover tokens in both key-value pairs and JSON structures. Delivered a security-focused feature (Data Masking Enhancement) with commit 8c93f5277d2df89b269a74b198de69720d526b4f, addressing ECWID-156365. Business impact: reduced risk of sensitive token exposure in logs and outputs, strengthening compliance posture for API clients. Technical accomplishments include expanding masking patterns in Java, ensuring compatibility with existing logging, and delivering the change via a standard commit-driven workflow in Ecwid/ecwid-java-api-client. Technologies/skills demonstrated: Java, secure logging, pattern-based data masking, code review and collaboration, and data security best practices.
