Golang Developer / Backend Engineer (Contract)

Built and operated production backend services in Go, taking ownership across backend architecture, caching, deployment, observability, and production reliability.

  • Designed and implemented a dedicated Redis caching layer to reduce repeated database and backend operations, improve response times, and provide a scalable foundation for increasing application traffic.
  • Owned the Redis service end-to-end, including architecture, implementation, deployment, and production operations.
  • Engineered production Go services with a focus on reliability, maintainability, and efficient request handling across backend workflows.
  • Managed backend deployment workflows and production infrastructure, ensuring services could be deployed, monitored, and maintained reliably.

PR #12

  • Designed and implemented a live node-status API exposing uptime, verification and attestation counters, and relayer balance, giving operators real-time visibility into node health and operational state.
  • Built a lock-free metrics layer using AtomicU64 for thread-safe counter updates across concurrent Axum request handlers without introducing mutex contention.
  • Implemented API-key authentication with constant-time credential comparison using subtle::ConstantTimeEq, reducing exposure to timing-based credential attacks.
  • Introduced a 30-second TTL-based balance cache to eliminate redundant RPC calls, reducing unnecessary upstream requests while keeping operational data reasonably fresh.
  • Added comprehensive unit tests covering the metrics, authentication, caching, and status-handling logic to improve confidence in the new production-facing functionality.
