PROFILE
Artem Yavruyan
Artem Yavruyan developed and maintained core backend features and robust testing infrastructure for the peer_network/peer_backend repository over ten months. He delivered user-facing capabilities such as moderation workflows, transaction validation, and multipart post creation, while systematically expanding automated test coverage to reduce production risk and improve release reliability. Artem applied TypeScript, JavaScript, and SQL to implement granular error handling, authentication, and data modeling, and refactored test suites for maintainability and CI efficiency. His disciplined approach included stabilizing flaky tests, enhancing GraphQL and API validation, and enforcing data integrity, resulting in a more reliable, maintainable, and business-aligned backend platform.

Nov 1, 2025November 2025 Monthly Summary - Peer Backend (peer_network/peer_backend) Key deliverables and business value: - Strengthened moderation and governance via GraphQL API: Delivered consolidated moderation actions, visibility controls, illegal content handling, reporting, and management of user posts/comments. Implemented end-to-end tests for moderation actions, visibility transitions, boosted/pinned content, blocked users, and active reports, improving policy enforcement and user safety. - Transaction validation rules: Enforced strict transfer message and amount constraints (length/character rules, MAX_DECIMALS, MIN_AMOUNT) with accompanying tests to prevent invalid transactions and improve financial data integrity. - Test coverage, stability, and maintainability: Expanded and stabilized the moderation test suite, refactored utilities (merge of listUsers into listUsersV2, usage of visibilityStatus), and added tests for listComments, listBlockedUsers, hasActiveReports, and post-moderation reporting. Addressed test failures and updated internal scripts to guard against internal server errors. - Overall impact: Enhanced safety and compliance posture, reduced risk of illegal content exposure, and more reliable governance workflows. Improved developer velocity through better test reliability and clearer API behavior. Technologies/skills demonstrated: - GraphQL API design and governance workflows - Content moderation, visibility management, and reporting mechanisms - Test-driven development, test automation, and refactoring for stability - Test coverage expansion for edge cases (illegal content, pinned content, reports) - Data validation discipline for financial-like transfer operations
