Summary
👤
Senior🎓
Top SchoolGreg Rosenbaum is a software developer with 13 years’ experience turning experimental B2B SaaS prototypes into resilient, enterprise-grade distributed systems. He has repeatedly taken seed-stage ideas through PoCs and strangler-pattern migrations to scalable platforms, improving throughput (25x in one case) and cutting infrastructure costs with pragmatic cloud patterns like GKE, serverless, and Spot VMs. Comfortable across Node.js, Python, React, and low-level browser internals, he blends deep technical problem-solving (including Chromium/V8 instrumentation) with product-focused specification and cross-team communication. A hands-on leader and mentor, he standardizes toolchains (Zod, Helm, rxjs) to reduce onboarding friction and accelerate delivery. Based in London, he thrives where technical decisions have real business impact and where ambiguous requirements must be translated into concrete engineering outcomes.
