I’m Greg — a backend-first dev who likes building secure, scalable systems. Here’s a bit about who I am, what I’ve worked on, and what I care about.
DRIVEN TO
SUCCEED,
SIMPLE.
Who am I?
Hey, I’m Greg, a software engineer building secure, scalable systems with privacy in mind. I’ve worked across diverse tech stacks in both industry and startup settings, tackling infrastructure, backend, and product challenges. Right now, I’m at Entrepreneurs First, exploring early-stage ideas. If you’re into secure system design, FinTech, or startups, let’s chat!
What do I do?
I build simple, scalable, and secure systems. My focus is on creating software that is not only functional but also easy to maintain and extend. Right now im working on early-stage ideas at Entrepreneurs First.

If you have any questions or just want to chat, feel free to reach out to me on social media or via email. I’m always open to new opportunities and collaborations.
Hobbies
When I’m not building systems, I’m usually on a trail, on a wall, or somewhere with a guitar and a Guinness. I code for fun, 3D print questionably useful things, and compete for the fun of figuring things out.
