Engineer. Builder.

Charlotte, NCSenior Software Engineer @ Medshift

I build commerce platforms, AI products, and tools for developers. From a million-order storefront to a climbing app born at the bouldering gym, I like making software people actually use.

01 / Selected work

From an itch to a product.

Two things I wanted to use. So I built them.

Cima's public coaching preview with pose tracking and climbing technique scores

Climbing + AI

Cima

A second pair of eyes for your next climb.

I built Cima to get better feedback from my own bouldering sessions: upload a climbing video, review your technique, and track progress over time.

The product challenge: make video feedback useful between climbs, alongside session history and grade progression—not just a one-off AI response.

Fashion + AI

Drezzi

Try the outfit. Keep your own reflection.

I built a virtual try-on app that pairs a photo of you with clothes you upload, then saves the results in lookbooks.

The product challenge: connect garment uploads, personal photos, multiple poses, and saved looks into a single try-on workflow.
