Senior Software Engineer / Manager – Resume

Hi, I’m Thomas McMahon—a Senior Software Engineer and Engineering Leader with 25+ years of experience in software development, digital consulting, and building modern web applications.

At Nerdery, I’ve partnered with companies from small businesses to Fortune 500 companies, leading teams that have delivered hundreds of projects across industries like healthcare, e-commerce, and enterprise technology. I specialize in modern front-end development with React, Next.js, and GraphQL, always with a focus on performance, accessibility, and user experience.

What sets me apart is my dual expertise: I can architect and build sophisticated technical solutions while leading and mentoring high-performing engineering teams. Whether I’m conducting code reviews, facilitating client discovery sessions, or implementing company-wide processes, I believe in clear communication and empowering others to do their best work.

I’m passionate about creating a web that’s not just functional, but truly inclusive—one that works beautifully for everyone.

Currently based in the Minneapolis, Minnesota area, and always interested in connecting with fellow builders, leaders, and anyone working to make the web a better place.
