ENGINEERING
Justin plays in backend infrastructure and high-scale system design as a Principal Engineer.
Justin tends to play in backend infrastructure and high-scale system design as a Principal Engineer at TheGP. He’s built his career around designing, implementing, and operating high throughput distributed systems across a number of verticals, including social gaming, consumer messaging, and enterprise software.
Portfolio companies
Previous experience
MessageMe
Justin was the co-founder and CTO of MessageMe, which was a mobile messaging product that was acquired by Yahoo!
Google Cloud
Most recently, Justin was a backend infrastructure lead for Google Cloud, where he focused on modernizing the App Engine stack and building an asynchronous eventing system for triggering Serverless workloads.
For Justin, the work he enjoys most is building things that have a tangible utility for users.
Highlights
Coming at product-building from different directions
A proven generalist, Justin has done everything from optimizing an isometric rendering engine to deploying a globally distributed WebRTC fleet. This technical flexibility has even allowed him to plug into a crypto infrastructure project at TheGP, where a part of his day job now includes acting as a novice security engineer.
Building better hammers
At this point in his career, Justin has acquired broad domain expertise that allows him to understand complex systems from top to bottom. Leveraging this knowledge base, he’s able to construct bigger solutions to novel problems, always in the pursuit of creating software that delivers meaningful utility.
