PROFILE
Iain Macdonald
Over 21 months, contributed to buildbuddy-io/buildbuddy by engineering robust backend systems focused on caching, authentication, and observability. Developed and maintained features such as a proto-based cache proxy registry, customer-managed encryption key services, and advanced executor labeling, leveraging Go, gRPC, and Prometheus for scalable, secure infrastructure. Enhanced reliability through LRU-based caching, JWT authentication with ES256/RSA support, and resilient CI/CD pipelines. Improved system monitoring with Grafana dashboards and OpenTelemetry integration, while strengthening security via IP rules enforcement and encryption. Addressed operational challenges with targeted bug fixes, comprehensive testing, and documentation, resulting in a maintainable, high-performance distributed build platform.

May 1, 2026May 2026 performance summary: Delivered foundational cache proxy management capabilities, improved reliability and observability, and strengthened security/compliance. Key wins include establishing a proto-based CacheProxyRegistry with Redis-backed liveness and a GetCacheProxies RPC, enabling scalable registration and visibility of live proxies; shipping the Cache Proxies UI and API key workflow to empower self-service proxy provisioning and monitoring via the /cache-proxies page. Addressed correctness and stability by fixing the sum/rate ordering on the Cache Proxy dashboard and adding rate-window logic for stable metrics. Implemented reliability hardening for Cache Proxy RPCs (disabling gRPC client pooling where appropriate) and improved error handling for peer write paths. Strengthened security: executor-label access control gates debugging features, and ES256 JWTs default, with deprecation of related experiments; removed a deprecated flag to reduce confusion. Expanded observability and developer tooling with FileWriter temporary-file metrics, expanded logging for executor labels, and BYOP documentation and pool-size configurability. These changes drive business value through scalable proxy registration, faster provisioning, better telemetry, and a stronger security posture, while preserving backward compatibility and aligning with existing access-control patterns.

Mar 1, 2026March 2026 was focused on consolidating caching, hardening IP rules enforcement, and elevating security, with a strong emphasis on performance, reliability, and maintainability across the BuildBuddy platform. Key work spanned centralizing and hardening caches via a new LRU framework, enabling remote IP rules services, and integrating Cache Proxy protections with robust testing. We also advanced JWT-based security, fixed critical goroutine leaks, and improved CI readiness. Summary of impact: - Consolidated caching through a centralized LRU core and introduced an expiring LRU, enabling safer, thread-safe caching and reducing cache fragmentation and contention. - Replaced multiple ad-hoc caches with lru.LRU instances (imageExistsCache, iprules caches, tag-to-digest and API key caches), boosting throughput and memory predictability. - Introduced IPRulesService and a remote IP rules provider with LRU-backed caching, plus a dedicated GetIPRules RPC, enabling dynamic, scalable IP rules distribution and enforcement. - Enhanced Cache Proxy with an ip_rules_enforcer, remote IP rules caching, deduplication of in-flight fetches, and integration tests to validate IP Rules behavior end-to-end. - Implemented comprehensive IP rules enforcement improvements and bypass semantics for internal system RPCs, including header-based bypass signaling, to ensure legitimate internal communications aren’t blocked. - Strengthened security and observability: added ES256 support for JWT verification, HS256 fallback authentication, and metrics around JWT verifications. - Stabilized runtime behavior: fixed Goroutine leaks in rpcutil.Sender, improved server shutdown handling for background goroutines, and added build/CI improvements for better release velocity. Top 3-5 achievements: 1) Centralized LRU core and expiring LRU that underpins multiple high-traffic caches, yielding measurable performance and memory stability gains. 2) IP Rules governance: new IPRulesService, remote IP rules provider, and Cache Proxy integration with deduplicated fetches and end-to-end tests, enabling scalable, secure policy enforcement. 3) Cache Proxy hardening: ip_rules_enforcer integration and bypass semantics to preserve legitimate internal traffic while enforcing IP rules. 4) JWT security enhancements: ES256 support, HS256 fallback, and observability improvements for verifications. 5) Reliability improvements: fixed goroutine leak in rpcutil.Sender and improved shutdown reliability for background tasks, reducing tail-risk in production. Technologies/skills demonstrated: - Go concurrency, channel and goroutine hygiene, and regression testing. - LRU-based caching patterns and cache invalidation strategies. - gRPC service design, including remote service patterns and enrichment of contexts across RPCs. - IP rules enforcement architecture, bypass semantics, and remote policy provisioning. - JWT handling across ES256/HMAC paths with robust verification and metrics. - CI/Build reliability improvements and buildfix automation.

Oct 1, 2024October 2024 — Buildbuddy (buildbuddy-io/buildbuddy): Key features and fixes delivered to boost performance, reliability, and security. AtimeUpdater throughput improved: larger digests-per-batch and higher queue capacity; introduced graceful shutdown and queue draining for robust lifecycle. Fixed ByteStreamServer resource leak by ensuring decompressorCloser is always closed. Fixed CASProxyTest flakiness by making atime-update interval deterministic in tests. Encryption-enabled data path protection introduced via central EncryptionEnabled utility to prevent local reads/writes for tenants with encryption enabled, ensuring encrypted data is managed by remote cache. These changes translate to higher throughput, fewer runtime leaks, more reliable tests, and stronger data security for encrypted tenants.
