Seth Choi is a Senior Software Engineer based in San Diego with 11 years of experience crafting polished, user-focused front ends and reusable component systems for companies like Squarespace and HubSpot. He blends strong UI design sensibilities—illustrated by D3 visualizations and a coach reports landing page for the KA Lite project—with pragmatic engineering: building mono-repo frameworks and in-house component libraries to scale teams and product consistency. Seth often takes on tech-lead responsibilities, driving architecture, onboarding flows, and cross-team delivery while mentoring healthy team culture. Beyond code he’s a visual artist and DJ, bringing a creative-first mindset to product polish and interaction design. He’s also intellectually curious about AI, global systems, and the sciences, which informs both his approach to problem solving and feature design.
