I’ve collaborated with Paul during a crucial phase of a client’s transformation initiative. I brought him into the project based on a trusted recommendation, and it turned out to be one of the most strategic decisions we made. With decades of experience in technology and business, I was struck by Paul’s blend of technical expertise and strategic foresight. He has a rare ability to convert vision into execution, modernizing how teams operate while ensuring long-term sustainability. Paul introduced agile methodologies that allowed us to shift from rigid development cycles to rapid, iterative delivery. This significantly accelerated our ability to deliver value. Paul’s strength lies in balancing big-picture thinking with detailed execution. He’s analytical, intuitive, and responsive to shifting priorities. He streamlined processes, introduced scalable architecture, and guided the team through continuous improvements—all with unwavering integrity and transparency. As a leader and consultant, Paul communicates clearly, mitigates risks early, and inspires high performance. He led a diverse, distributed team with empathy and precision, aligning technical contributors and stakeholders alike. Every milestone was delivered reliably, and the results surpassed expectations in terms of usability, durability, and strategic value. Paul leads with a strong sense of purpose. He brings intellectual clarity and emotional intelligence to every engagement. Any organization would benefit immensely from his leadership, systems thinking, and commitment to meaningful outcomes. Please feel free to contact me directly for more insight. Sincerely, Henry C. Dittmer Sensible Leadership Coaching, LLC henry@sensible-leadership.com +1 (303) 810-4905 BEN TOMLIN (btomlin@uw.edu) I’m pleased to share my wholehearted recommendation of Paul Stewart. 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 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. Warm regards, Shannon Berg Founder & CEO shannon@bergassociatesnw.com 503.347.8822 TYSON BROWN (brown.tyson@gmail.com) It is my pleasure to recommend Paul Stewart for senior leadership and strategic delivery roles. I worked closely with Paul in my capacity as a Product Manager, where he served as a consulting partner and development lead to help us drive and deliver compelling capabilities to our customer base. When we faced the challenge of building a new system under a short timeline and with high technical expectations, Paul’s team stepped in and delivered beyond expectations. He quickly absorbed the complexity of our business problem and translated it into a thoughtful, strategic technical solution. He worked with us from discovery through deployment, balancing technical feasibility with user-centric design and organizational priorities. Paul’s leadership was crucial to the success of this initiative. He assembled and guided a hybrid team of frontend, backend, and QA engineers who worked in close collaboration with our in- house teams. His calm and focused presence helped maintain momentum through tight deadlines, shifting requirements, and technical unknowns. The product we launched achieved exceptional adoption rates and remains a critical, high-use capability today. As a development manager, Paul consistently solved difficult problems with elegance and empathy. He is fluent in both the language of business and technology, serving as a vital bridge between strategic goals and technical execution. His standards for quality and innovation were evident in every deliverable. Equally important, Paul led with integrity and transparency. He built trust quickly with our teams and fostered a culture of accountability within the distributed team he managed. His hybrid-first team structure and leadership approach predated current remote trends by over a decade, serving as a model for high-performing global teams. Paul brings strategic thinking, operational discipline, and a collaborative spirit to every engagement, making him a valuable asset to any organization.
