Welcome to my corner of the web. Feel free to take a look around maybe checkout some of my articles or reviews over on my blog. If you feel the need please reach out to me via my contact page.

I'm a full stack JavaScript software engineer with extensive experience in Ad Technology, Data Analytics, Prebid, Next, React, and Nest. I've built CI/CD pipelines from scratch via GitHub Actions and Atlassian Bamboo leveraging Amazon S3, Cloudflare, and Fastly. Recent interests have me exploring the world of AI/ML using XGBoost in combination with multi-agent LLM systems.

Currently, I work at as a Lead Engineer. My primary focus is building and maintaining Spiny's client side library which is a multi-tenant & multi-level modular library for ads, analytics, and AB testing. I've built out many different integrations with various systems including: JWPlayer, EX.CO, Nativo, Taboola, Outbrain, Prebid, Amazon UAM/TAM, WordPress, YouTube, Connatix, Confiant, GeoEdge, OneTrust, TCF, USP, LiveRamp, Googletag, and many more.

Libraries I've developed have been deployed across many sites including CNET, TIME, Sports Illustrated, CBS Sports, CBS News, Comicbook, and many more.
