Engineering Excellence, Automating Trust, One Pipeline at a Time.

Lead Developer Experience (DevEx) Engineer passionate about optimizing developer workflows and accelerating continuous delivery. With over five years of experience in DevOps, backend development, and cloud infrastructure, specializing in Java, Jenkins, AWS CDK, and Spring Framework.

At EVRi, I’ve led initiatives to improve CI/CD pipelines, enforce code quality gates, and introduce ephemeral "pop-up" testing environments, making deployments faster and safer. I’m passionate about fostering inner-source collaboration and building scalable infrastructure that empowers teams to ship high-quality code they can feel proud of with confidence.

Outside of work, I created Streamdeckd a lightweight Golang-based Elgato StreamDeck driver for Linux, showcasing my passion for automation and open-source tooling.

Experience

Evri (Formerly Hermes)

Lead DevEx Engineer - Jan 2024 - Present - At EVRi, I spearheaded initiatives to enhance developer workflows, optimize CI/CD pipelines, and improve system reliability.

I also drove the migration from legacy clusters to product-aligned infrastructure and collaborated with service teams to implement continuous deployment while maintaining high reliability. My work focused on automation, scalability, and fostering a culture of inner-source collaboration.

StreamDeckD

January 2020 - Present
Technologies: Formerly NodeJS & Electron, Presently Golang daemon & Fyne.io GUI
Summary: A SystemD daemon and GUI application that allows for the usage and configuration of all Elgato StreamDeck devices connected to devices running Linux
After mistakenly purchasing an Elgato Streamdeck without checking for official support for my Linux machine, I found myself with a new project, which during the course of I've learned:
- How to intercept and reverse-engineer USB packets
- How to manipulate both still images and animated GIFs
- This was my first project using Golang, in which I've learned to create a plugin system for StreamDeckD which allows 3rd parties to develop plugins without having to modify the core daemon

Handl

January 2025 - Present
Technologies: Typescript AWS CDK, leveraging AWS Lambda behind AWS API Gateway for a low-cost solution
Summary: Creating a service to allow powerlifters to connect with handlers for competition days
I was brought in to help automate some of the workflow around Handl, to allow the rest of the team to focus on growing the service, rather than managing emails, by automatically orchestrating contact between a lifter, and all registered handlers that meet the requirements, and are within range of the competition
