PROFILE
Andrew Mcgivery
Andrew McGivery contributed to the apollographql/router project by engineering robust backend features and critical bug fixes that improved data routing, configuration, and reliability. Over nine months, he delivered enhancements such as dynamic header management, JSON selection utilities, and connector-level traffic shaping, using Rust and TypeScript to ensure type safety and maintainability. His work included refining HTTP transport, implementing TLS for connectors, and expanding schema validation, all while maintaining strong test coverage. By addressing issues like header propagation and directive indexing, Andrew enabled safer integrations and more expressive configurations, demonstrating depth in API development, GraphQL federation, and system design.

Sep 1, 2025In September 2025, delivered a critical correctness improvement in the apollographql/router project by addressing directive indexing in the connectors subgraph. The fix ensures non-connect directives no longer skew index counts in snapshot files and that positions in the schema representation accurately reflect the intended structure, enhancing reliability for downstream tooling and consumers.

Jan 1, 2025January 2025 monthly summary for apollographql/router: Focused on delivering a targeted performance improvement to the query prewarming path for persisted queries, with documentation and clear changes to randomization boundaries. No major bugs fixed this month; emphasis was on reliable feature delivery, maintainability, and measurable improvements to cache distribution across the Router fleet. Key outcomes include a feature delivery that enhances prewarming by including persisted queries in randomization and ensuring separate randomization for pre-warmed queries (pqs) from other cache keys, supported by a formal changeset and associated code updates. The work is expected to reduce prewarm latencies and improve cache hit rates across the Router fleet, contributing to faster query responses for persisted queries.
