Rockstar🎓
Top SchoolWalter Tan is a Senior Software Engineer in New York with 11 years of experience building web platforms and operational tooling across companies like MongoDB, Brex, Squarespace, TripleLift, and Course Hero. He began his career as a chemical engineer, bringing a rigorous, data-driven approach to software problems—automating reporting and financial tracking early on and later modernizing services with type safety, CI/CD improvements, and observability. Walter has led migrations and large-scale data work (budgets ledger, budget distributions), introduced safer deployment practices like canary releases, and delivered customer-facing features that reduced manual effort and audit times by significant margins. He pairs backend systems thinking with frontend pragmatism (TypeScript adoption, analytics instrumentation) and a penchant for mentoring and onboarding engineers. Notably, his cross-disciplinary background often surfaces as practical process automation and measurable efficiency gains rather than just abstract architectural changes.
