Thomas Lesperance
I’m Tom, and I’ve spent over a decade diving deep into the world of web development. My journey has taken me through various roles where I’ve had the chance to work with technologies like Angular, React, and Vue. What excites me most is the opportunity to create dynamic applications that not only meet business needs but also enhance user experiences. I thrive on solving complex problems—there's nothing quite like the satisfaction of turning a challenging project into a successful solution.
One of my proudest moments was leading a team at T.K. Elevator (formerly known as Thyssenkrupp) to migrate a complex Angular application from version 1.5 to 15 over two years. This wasn’t just about updating software; it was about enabling the client to save significant costs while improving their overall system performance. It’s these kinds of challenges that keep me motivated and engaged.
During my time at The Home Depot, I took on the challenge of enhancing their shopping cart testing suite. By streamlining processes, I managed to reduce execution time by an impressive 75%, bringing it down to just over four minutes! This not only improved efficiency but also allowed the team to focus on more strategic initiatives rather than getting bogged down by lengthy tests.
I also have experience working with Georgia Power Company where I consolidated multiple departmental tools into one cohesive system. This effort resulted in a notable 22% increase in usage—a clear testament to how effective design can drive user engagement. My earlier role at Westinghouse Electric Company taught me valuable lessons about revenue generation and customer retention as I spearheaded an aftermarket support program that generated $0.5M in new revenue.
Outside of work, I'm passionate about using technology for good. My early research involved developing clinical devices aimed at improving therapy outcomes for children with mental disabilities—an experience that deeply resonates with my belief in making a positive impact through innovation.
