Top SchoolKarl Castillo is a front-end-focused software engineer with 15 years of experience, currently the sole Frontend Architect and Founding Member of Technical Staff at a stealth startup in Vancouver. He has a strong track record building scalable front-end architectures and reusable component libraries across gaming, SaaS, and startup environments, from Gatsby/React microsites to data-heavy dashboards. Known for bridging design and backend teams, he owns UX realization, data contracts, and deployment tooling end-to-end while mentoring engineers and driving engineering best practices.
