PROFILE

Tom Brewster

Over a three-month period, Brew42 developed and enhanced feature flag and SBOM flow capabilities across the snyk/cli-extension-os-flows and snyk/cli repositories, focusing on scalable configuration and improved reliability. They implemented multi-flag evaluation systems and integrated build scope controls for Maven and NPM, using Go and TypeScript to support cross-repository consistency and safer rollouts. Brew42 also refactored code for maintainability, updated dependencies for security, and hardened error handling in the Snyk CLI, reducing triage time and risk. Their work demonstrated depth in backend development, dependency management, and instrumentation, resulting in more robust, configurable, and secure multi-language build workflows.

March 2026 (2026-03) — Snyk CLI (snyk/cli) stability, robust error reporting, and security hardening. Key outcomes include RunTest error handling hardening to refine catalog error identification and messaging; comprehensive security and dependency upgrades across the CLI tooling with synchronized package-locks; and targeted catalog and tooling updates to improve reliability and compliance. Business impact includes clearer failure signals reducing triage time, safer dependencies lowering risk across downstream builds, and reproducible builds via locked dependencies. Technologies demonstrated include Go tooling (go mod tidy), Node.js/npm dependency management, tar packaging, Maven plugins, Python plugin, SBOM tooling, and error catalogs.

January 2026 — Delivered scalable feature flag and SBOM flow capabilities across two repositories, driving business value through better visibility, reliability, and maintainability. Key outcomes include feature flag-driven Maven/NPM build scope in SBOM flow, code-quality improvements, and a new multi-flag configuration approach for the Go ecosystem. Dependency updates to Go modules enhance stability and security. The work lays groundwork for instrumentation and faster, safer feature rollouts across multi-language stacks (Java/Maven, Node/NPM, Go).
