Hand me any platform.

I'm a web developer, about a decade in. I've built on Shopify, BigCommerce, Episerver, WordPress, and a few stacks I'd rather not name in public — mostly JavaScript, SCSS, C#, and SQL. Hand me a platform I've never touched and give me a few days; that's basically how I ended up running our Shopify experimentation setup when clients started moving there.

These days, I'm an Optimization Developer at a CRO agency. I build A/B tests on platforms like Convert, Adobe Target and PostHog. A lot of the quieter work is the measurement itself: setting up GA4 and GTM the right way, so the data every test leans on is actually trustworthy. When the front end needs data it can't reach on its own, I'll write an AWS Lambda for it.

More and more, my real edge is AI tooling. I build the agent workflows and dev setups — Claude Code, custom skills, scripted pipelines — that have multiplied my output, routinely turning days of work into hours. Figuring out where these tools actually fit a workflow, and wiring them in so they pay off, is its own skill, and one I've gotten good at fast.

Give me a goal and I'll find a way to get the test built, shipped, and tracked, whatever platform it's on. Turning "can we even test this?" into something live is the part I'm best at.
