Engineering leader driving $130M+ in measurable revenue through experimentation.

Michael joined AEO as a frontend developer, working on websets late into the night with our scrappy development team at the time. Since then, Michael has grown into a leader and become a champion for optimization in the webset space as a key player in our Content Strategy team. He was highly influential most recently in leading content architecture with Contentstack, developing a foundation hands-on for our solution to grow and scale for all shopping channels. He has also been a passionate leader in the A/B testing and experimentation area, pioneering efforts to mature our capabilities and integrations through Tealium, Google Optimize, and this year with our switch to Optimizely. Michael was always a strong advocate for his team and the work to better the experiences for our AEO customer.

I worked closely with Mike over the last year and a half as my engineering lead and solutions architect supporting A/B testing and third party integrations. Mike's leadership and expertise in this space allowed us to build and grow our testing program exponentially beyond the goals we set in the first year. He's knowledgeable and patient and a solid team player, always addressing challenges with a positive attitude and a viable solution. His contributions were instrumental in building an efficient, effective and, most importantly, happy team. 10/10 recommend!

Working alongside Michael as a cross-functional partner at American Eagle and on several freelance projects has been a great experience. From a designer's perspective, he brings a strong mix of technical knowledge, collaboration, and strategic thinking to every project. One of his biggest strengths is his ability to lead and deliver end-to-end projects — from early ideas and problem-solving through development, launch, and continued improvements — while always keeping both the business and user experience in mind. I would strongly recommend him to create a supportive and positive environment that makes working together both productive and enjoyable.

I have had the pleasure of working with Mike for 7 years. His knowledge & insights were always consistent and clear that helped our developer-designer relationship be a supportive and innovative one. He is always open to new ideas and a team player in making those ideas come to life with the lowest possible effort and the highest reward for both the business and the customer. From a designer's perspective, Mike is an ideal teammate for pushing boundaries and launching successful digital products.

I have worked with Michael Hallman for 13 years at American Eagle. He has really grown over the years from starting as a UI developer to building out an entire AB Testing team and process at American Eagle. I highly recommend Michael as a fantastic leader, co-worker, and innovator in his area of expertise.

I had the opportunity to partner with Michael at American Eagle on recruiting efforts and truly enjoyed working with him. He was responsive, insightful, and thoughtful in his feedback, which helped keep the hiring process moving smoothly. I'd gladly partner with him again.

Michael has always been one of the most dependable people in the UI team. Excelling at organizing and kicking off projects, never shying away from daunting workloads.
