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.
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.
- node-email-verifier – Production-grade email validation for Node.js, including MX checks, disposable email detection, and caching.
