About

Zach Mumbauer

Currently engineering high-scale financial systems as a Senior Software Engineer at PayPal. I hold a bachelor's degree in computer science from George Washington University and a master's degree in data science from Bellevue University.

I work on production infrastructure supporting millions of real-world transactions and prioritize reliability, maintainability, and clean architecture under real operational pressure.

“I believe in disciplined execution and steady, iterative improvement — in my code and in myself.”

Beyond the keyboard

01Leadership
Eagle Scout

Eagle Scout.

Earned the rank of Eagle Scout — achieved by fewer than 4% of scouts. The discipline, leadership, and service it required still shape how I approach every project.

02Creative

Musician.

From vocals on the Carnegie Hall stage to drums in my basement, guitar in my office, and piano in my kitchen — music has always been a huge part of my life.

03Explorer

World Traveler.

All 50 states checked. 25+ countries explored alongside my dad, with no plans of slowing down. Travel has given me perspective and adaptability no classroom could.

04Maker

Builder.

When something captures my interest, I commit fully. I’ve designed software systems, built products from scratch, and even designed my own house in CAD and saw it constructed in the real world. I’m drawn to understanding how things work and bringing ideas to life.
