I turn messy business operations into software people actually use.

I'm Efraim Wachsman, a founder and product engineering leader based in the New York area. I build SaaS platforms, internal systems, and complex integrations for companies that need someone who can understand the business, shape the product, architect the system, and stay hands-on in the code.

I founded Campflow, a SaaS platform for camps and day camps, and through RapidQuill I provide fractional technology leadership and senior product engineering consulting for growing businesses.

What I do

I help companies build, rebuild, and scale business-critical software.

  • Product leadership: roadmaps, customer discovery, pricing, onboarding, support, retention, and business operations.
  • Engineering leadership: architecture, full-stack development, API integrations, payments, code review, deployment, and production support.
  • Hands-on execution: SaaS platforms, internal tools, e-commerce workflows, donation systems, school software, travel booking, and complex integrations.
