What I'm looking for

I look for roles where I can build and maintain scalable web systems, mentor teams, work with modern JavaScript stacks and cloud platforms, and contribute to open‑source while improving CI/CD and automation.

I am a senior full‑stack JavaScript engineer with a strong background in building production web applications, serverless systems, and developer tools. I design and deploy end‑to‑end solutions using React, Node.js, and modern cloud platforms, and I publish and maintain open‑source packages on NPM.

At BeyondTrust I rewrote an LMS from scratch, led technical hiring, built automation and Slack integrations, and redesigned backend infrastructure to cut substantial monthly costs. I have built and deployed NPMRunner (npmrunner.com), a live in‑browser sandbox for safely executing NPM packages, and maintain CI/CD pipelines and testing suites to ensure reliability.

I mentor junior engineers, drive code quality through testing and reviews, and enjoy solving infrastructure and automation challenges using AWS, Docker, GitHub Actions, and other modern DevOps tools. I am committed to delivering maintainable, performant systems and contributing to the open‑source community.
