Hey, I’m Aaron — a software engineer focused on building scalable backend systems and APIs.
I’m especially interested in how complex systems behave under real-world conditions, whether that’s high-throughput software, rockets in flight, or imaging deep-space objects.
Here you’ll find a mix of software projects, launch logs, and an astrophotography gallery — all centered around exploring and understanding systems from different angles.
About Me
My name is Aaron Barczewski (pronounced “bar-chess-ski”), and I am a senior software engineer with nearly a decade of experience designing and building backend systems across the defense, marketing, and telecommunications industries. I specialize in developing scalable services and distributed systems using API-driven architectures, with a strong focus on performance, reliability, and maintainable system design.
I graduated from Colorado State University in 2016 with a Bachelor’s degree in Computer Science. Prior to my career in software engineering, I served in the United States Army as an intelligence analyst and deployed to Afghanistan in 2010.
Outside of engineering, I enjoy astrophotography—capturing images of deep-space objects—designing and building rockets, and playing the drums.
Software Engineering
My software engineering work focuses on building scalable backend systems and APIs with an emphasis on performance, reliability, and clean architecture.
You’ll find a mix of projects, case studies, and articles — from hands-on implementations to deeper breakdowns of system design decisions and real-world tradeoffs.
Rocketry
My rocketry work focuses on designing, building, and testing rockets, with an emphasis on flight stability, performance, and iterative improvement.
You’ll find a collection of launch projects, along with detailed reports that break down flight behavior, results, and the lessons learned from each test.
Astrophotography
Astrophotography is an extension of my interest in complex systems — combining optics, exposure control, and image processing to capture detail from the night sky.
The gallery showcases finished images, while the articles go deeper into the technical side — covering workflow, equipment, and lessons learned from each session.
