Coding since 2017 · Shipping since 2019

Jacy

Software engineer. Product builder. Professional bug negotiator.

I design, ship, and operate software, from backend systems to developer tools and apps people use. AI is in the toolbox, not the entire personality.

About

From the first commit to the production fix

I like building the whole thing: useful interfaces, solid backends, and the infrastructure in between.

Projects

Things I've built and shipped

Real products first, experiments close behind. Here's the engineering behind the things I spend my time on.

Beyond the main builds

Engineering notes

Behind the build

Some of the decisions, dead ends, and experiments behind what I build. More useful than pretending every first attempt worked.

September 2024

Won 2nd place in a human pose estimation hackathon and earned an internship.

August 2024

Built solarVert, a solar panel management app for a hackathon.

February 2024

Placed 3rd in a hackathon building a hybrid CNN + U-Net model.

November 2023
