Hi, I'm Jesse 👋

I build infrastructure and open-source developer tools that help engineering teams move faster, experiment safely, and scale intelligently.

At SurveyMonkey, I lead a team building growth, experimentation, and analytics platforms that process billions of events and power hundreds of experiments every month.


🚀 Systems at Scale & OSS in Production

Some of the tools and systems I’ve built:

  • Experimentation Infrastructure:
    Infra serving 1B+ requests per month with 99.9999% uptime and sub-10ms latency.

  • Analytics Pipeline:
    Scaled event processing to ~700 million events per month, powering company-wide product analytics.

  • Data Quality & Governance:
    Led initiatives achieving 100% taxonomy compliance and a 98.6% data usage rate, ensuring clean, trusted data.

  • Open Source Developer Tools:

    • node-email-verifier – Production-grade email validation for Node.js, including MX checks, disposable email detection, and caching.
      50,000+ weekly downloads.
    • traffic-splitter – Open-source proxy and middleware for canary deployments, A/B tests, and progressive rollouts.
    • async-tasker – Lightweight async task orchestration for high-volume systems.
    • SimpleBalancer – Minimalist load balancer for dev environments.
