I originally worked with Paul at the intersection of technology and learning innovation. At a time when digital collaboration was just beginning to take shape, Paul helped us envision and execute an ambitious solution that merged content, community, and utility in a single, intuitive system. What impressed me most was Paul’s ability to deeply understand the people at the center of the work. He actively engaged all stakeholders—whether strategic leaders or frontline users—to co-design meaningful outcomes. He guided us through choices with clarity, balancing bold innovation with practical delivery. The result was something visionary, built well before many of today’s mainstream tools emerged. And yet Paul’s strength wasn’t just technical—it was his commitment to solving real- world problems and advancing the mission through design and engineering. Even as our careers progressed, I’ve remained inspired by Paul’s foundational approach: engage thoughtfully, build iteratively, and measure success by impact. The principles I observed in those early years have clearly endured in the way he continues to lead teams and deliver change across sectors. I hold Paul in the highest regard as an innovator, mentor, and leader. Any forward-thinking organization would benefit greatly from his presence. Warmly, Ben Tomlin Senior Director, Communications [btomlin@uw.edu](mailto:btomlin@uw.edu) To whom it may concern, It’s my pleasure to offer this recommendation for Paul Stewart, whom I’ve had the opportunity to work with closely over the past several years on the development and continuous evolution of a specialized digital platform. From the beginning, Paul brought more than just technical expertise—he approached the work as a strategic partner. He took time to understand the needs and dynamics of our clients and end users, and he translated that understanding into a platform that was not only robust and secure, but remarkably intuitive. Paul was instrumental in shaping a product that handles complex workflows and permissions without ever losing sight of user experience. One of the things I appreciate most about Paul is his ability to manage complexity with calm clarity. He leads with thoughtfulness, listens intently, and never loses sight of what success looks like for the people on the other side of the screen. Under his leadership, projects were delivered on time and under budget, and always with scalability and adaptability in mind. Beyond the technical scope, Paul has been a valued thought partner as our work has grown. Whether navigating tight timelines or evaluating new opportunities, I’ve consistently relied on his clear thinking, grounded perspective, and collaborative spirit. His contributions have made our work stronger and more resilient. Any team would benefit from Paul’s ability to turn ambiguity into action and vision into results. I recommend him enthusiastically.

Being a software developer is more than just learning to program in a computer language. I have been building .NET web apps for years and multiplayer games since 2015, using Unity 3D using Photon Fusion (server-authoritative). I have also designed and/or worked on enterprise web sites from concept to deployment, some high-profile projects. I have served as a Senior or Lead Developer for years, mentoring other developers and encouraging them to use the latest technologies and best practices. For tutoring, I would focus on teaching design patterns, using events and encapsulation when designing applications and reinforcing the need to keep your skillset current as new technologies are released. I can give advice on how to focus your learning efforts to target specific types of development positions, and interviewing advice for finding a position within a software company. I had been a developer in C++ for about 10 years prior to using C# and focused on web technologies prior to working with Unity 3D. While I have primarily been using Unity 3D and Microsoft .NET / C# recently, I have also utilized legacy technologies like Classic ASP, VB and VB.NET, COM/DCOM, worked with Linux/PHP/MySQL from time to time, and worked with the Microsoft SQL Server/Express/CE products for 10+ years. I also have formal SCRUM training, which is used by many companies for handling team project management. For Unity 3D multiplayer networking projects I typically work with and recommend Photon Fusion along with PlayFab integrations, PlayFab Matchmaking, and PlayFab GameServers. If your college project is a "Concept to POC" type of project where the Proof of Concept is the working software required for a grade, then I will also teach you to use a Git repository to manage the project (or Plastic/UVCS for Unity projects). I can help you document the Project Scope, Functional Specs, create Design Documents, and build the presentation for your college project. We can build completed projects in a short time, both the user interface and the server components as needed. My focuses are Unity 3D multiplayer, C#, .NET Core
