ZACH FIRESTONE
SOFTWARE ENGINEER
Senior backend engineer based in Orlando. I build reliable, scalable systems — and I care about the code that runs them. Python, Go, Kubernetes, and whatever gets the job done.
01 // ABOUT
I'm a backend engineer and infrastructure specialist. I build services that scale, write pattern-driven code backed by solid tests, and own the full lifecycle — planning through deployment and support.
I've been keeping up with the AI side of things — building services that integrate with LLMs, experimenting with agentic workflows, and staying current on how AI tooling is changing the way we write and ship code. It's moving fast and I find it genuinely interesting.

Capacity // Feb 2023 – Present
I work on a team that maintains over 40 micro-services. Most of the applications are written in Python using Flask with GraphQL, including RESTful APIs as well as publishers and consumers that interact with RabbitMQ. Our main API uses Elasticsearch — one of my first projects was updating it to support partial word search. We use Datadog for monitoring and alerts, and everything runs in AWS with Kubernetes.
Towards the end of my first year we started identifying services we wanted to speed up by rewriting them in Go. Using my previous experience I helped lead that effort — rewriting apps and implementing new functionality.
