OLIVER KOZUB

I build and run Echo, software that has to work the second a drop goes live.

Who
Oliver Kozub. Software engineer, owner of Echo Laboratories.
Where
Chicago, IL. Computer engineering, finishing 12/2026.
01Today

I own and lead Echo Laboratories, a desktop app for purchasing limited retail goods and concert tickets.

We built it as a team. It started as an Electron app with a Node.js backend and a React frontend; when task load outgrew it, I moved the backend to Go. I built the user dashboard, plus live monitoring, alerts, and SMS, and built server-side integrations against PX, Imperva, and Akamai. I run weekly code reviews and debugging, and have presented weekly reports on application performance, optimization, and sales.

Alongside it, I’m finishing a Bachelor’s in Computer Engineering with a minor in Information Technology. Bilingual in Polish and English.
