My role
Full-stack engineer — gateway, caching, and codegen pipeline.
Overview
Consolidated a sprawl of REST and gRPC services behind a single federated GraphQL gateway. Wrote the schema composition layer, a Redis-backed per-field cache with automatic invalidation, and depth- and cost-limiting to keep expensive queries from taking the cluster down. Generated end-to-end TypeScript types from the schema so front-end and back-end could never drift apart.
Role & impact
Impact
Reduced average client round-trips from 7 to 1 and dropped p95 latency by 48%.
