I am a software engineer in the video games industry with interests in systems programming, networking, and making great tools. I am currently working at Demonware, the Activision studio behind the online functionality of Call of Duty, Tony Hawk's Pro Skater, and many other titles. I also hold Bachelor's and Master's degrees in Computer Science with great grades from Trinity College Dublin.

During 2025 Mia did an internship on our team at Demonware and frankly blew us all away. Mia is a very talented engineer. Her speed of delivery, her capacity of autonomy, her depth of technical knowledge and her attitude were phenomenal. It was a common phrase among the engineers on the team: "wait, she's an intern?". Mia worked on complex projects and tackled every challenge with aplomb. Any team would be incredibly lucky to have her!
- Gabriel Reyes, Engineering Manager @ Demonware (Activision Blizzard)
Mia is one of the most brilliant young developers I've ever had the pleasure to work with, she has consistently surpassed every expectation I've had and I expect to hear great things from her in the future.
- Vito Chiarella, Senior Software Engineer @ Demonware (Activision Blizzard)
I worked with Mia during her internship at Demonware. I was immediately impressed by her ability to get up to speed with current projects and make an impact very soon after joining the team. Mia is an excellent engineer who takes the time to learn, understand and come up with the best solution. We were lucky to have Mia on our team and I'd have no hesitation in recommending her for any future roles.
- Jack Halpin, Senior Software Engineer @ Demonware (Activision Blizzard)
I had the pleasure of leading the technical projects Mia contributed to during her internship at Demonware. She quickly ramped up in an exploratory space with minimal documentation and limited support, and her impact was immediate. Her pace of delivery and quality of contributions stood out, as did her ability to navigate ambiguity: identifying problems, theorizing solutions, and weighing tradeoffs with maturity beyond her experience level. Mia consistently demonstrated ownership, critical scrutiny, and a strong commitment to quality. She spoke her mind freely, brought a playful energy to the team, and delivered meaningful results that I could trust. Stack all of that together, and you get someone any technical leader would be lucky to have on their team.
