# Brad Hesse > iOS Software Engineer @ Facebook Location: San Mateo, California, United States Profile: https://flows.cv/brad I'm an generalist software engineer that loves building modern, performant apps & SDK's. I primarily enjoy working in Swift and Objective-C, but I also enjoy C# (Xamarin, Unity) and Kotlin/Java (android development), as well as some experience with React-Native. For the past few years, I've worked at Facebook / Meta on the Messaging Notifications team, building iOS and Android software to handle billions of notifications a day on Instagram, Messenger, and beyond. ## Work Experience ### Software Engineer @ Meta Jan 2019 – Present | Menlo Park, California ### Software Engineer @ OneSignal Jan 2017 – Jan 2019 | San Francisco Bay Area I’m an iOS engineer at OneSignal, which is the largest provider of push notifications, and sends billions of push notifications a day. As an iOS engineer at OneSignal, I maintain our iOS SDK (which is written in Objective-C) and I also work on our wrapper SDK’s for platforms like Flutter, Unity, and so on. I’ve spearheaded several major initiatives at OneSignal, such as iOS 12 changes, I added GDPR and email features for most of our SDK's, and so on. ### iOS Developer @ Hauls.com Jan 2016 – Jan 2017 | Las Vegas, Nevada Area I was the iOS engineer at Hauls and I built the Hauls.com app. The Hauls.com app was heavily focused on video streaming, so I had to become an expert at AVFoundation, HLS livestreaming, and caching. I wrote the app in Swift, and worked to make it as modular as possible. I also built a macOS “Admin” dashboard app to let team members at Hauls control the look and feel of the homepage, so I split up all of our core logic into a shared Swift framework. This had many benefits and made the app a lot easier to test as well. ### Software Developer @ Self Employed Freelancer Jan 2014 – Jan 2016 | Las Vegas, Nevada Area I was a freelance iOS developer for several years, building awesome apps for companies like Ztrack360 and Acarrot Inc. ## Contact & Social - LinkedIn: https://linkedin.com/in/brad-hesse-2957a852 --- Source: https://flows.cv/brad JSON Resume: https://flows.cv/brad/resume.json Last updated: 2026-03-22
