Hello, I’m Sean Gaffney

Engineering Leader
Product, Platform, & Infrastructure

I’m a software engineering leader focused on building strong teams and delivering impactful results. With a keen eye for data and a commitment to clear documentation, I lead teams to deliver large-scale, complex product, platform, and infrastructure projects. My goal is always to contribute to the success of the whole organization, not just individual pieces.

My deepest experience lies in frontend platforms and web performance, where I enjoy helping teams build faster, more reliable, and accessible web experiences that make real impact. But I'm at home across the stack, and love diving into new challenges and technologies.

Above all, I’m dedicated to supporting people. I believe that every challenge is an opportunity for a team to shine, and my greatest fulfillment comes from empowering others to do their best and most meaningful work.

Feel free to reach out anytime—I’d love to chat.
