Oct 1, 2025October 2025: Delivered real-time GraphQL subscriptions in Apollo Router and strengthened the developer experience and stability of the project. Key features delivered include GraphQL-WebSocket subscriptions with dual-protocol support (graphql-ws and subscriptions-transport-ws) and a plugin-based subscriptions architecture, supported by refactored WebSocket handling and dedicated subscriptions plugin. Tests were expanded to cover both legacy and modern websocket protocols. On the DX/CI side, updated development docs, cleaned CI configurations, improved test infrastructure for websocket integration tests, adjusted Nextest config, and implemented Renovate tweaks, along with CI cleanup such as PostgreSQL removal and file watching stability. The result is a more maintainable codebase, more reliable CI/test runs, and the ability to offer real-time subscriptions to customers. The work demonstrates proficiency in Rust, asynchronous systems, GraphQL, WebSockets, plugin architecture, test automation, and CI infrastructure optimization.

Jun 1, 2025June 2025 highlights for apollographql/router: Delivered targeted test improvements and codebase hygiene while removing unsupported GET batching, delivering more reliable behavior and maintainable codebase. Key features delivered: - Improved testing infrastructure and selective test execution: the test harness now correctly handles ParsedDocument, ensures schema parsing and query analysis occur in test setup, added a dedicated test for invalid enum input to strengthen GraphQL enum validation, and enabled test filtering by name in xtask to run targeted test suites. - Codebase cleanup and maintenance: centralized deprecated context keys, removed unused files, pinned the rhai dependency, refreshed Renovate Rust-version management configuration, and fixed xtask to locate the apollo-router crate. Major bugs fixed: - Removal of GraphQL GET batching support: eliminated batch_from_urlencoded_query and related logic; updated service layer to bypass batched URL-parameter requests. Overall impact and accomplishments: - Increased test reliability and quicker feedback with targeted test execution and stronger enum validation handling; reduced risk from deprecated keys and outdated dependencies; improved codebase maintainability and build reliability, contributing to smoother contributor onboarding. Technologies/skills demonstrated: - Rust, xtask tooling, GraphQL schema and query validation, test harness design, dependency management and Renovate config, and repository maintenance.
