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.
Battle-tested in hackathons and minor sleep deprivation
About
I like building the whole thing: useful interfaces, solid backends, and the infrastructure in between.

Projects
Real products first, experiments close behind. Here's the engineering behind the things I spend my time on.
AI-powered learning, career preparation, and hiring products. I build features and backend systems, including Jobpipe, a private pipeline that keeps job opportunities organized and up to date.
What I work on
Product engineering · Backend APIs · Private job-data pipeline
A gamified productivity app built around focused work, habits, and progress. As co-founder and CTO, I work across product decisions, engineering, and deployments.

Co-founder & CTO · Full-stack product · Deployment ownership
Beyond the main builds
Side projects still count. Especially the ones that solve real problems.
Engineering notes
Some of the decisions, dead ends, and experiments behind what I build. More useful than pretending every first attempt worked.
Publications
Peer-reviewed work from my research experiments.
Writing
Thoughts on building, research, and whatever else is on my mind.
