Kingston, Ontario · Remote Canada

Senior Frontend Developer with 10+ years shipping production React and TypeScript systems in healthcare, fintech, public sector, and commerce. I build design systems and shared libraries teams adopt, ship WCAG AA interfaces, and structure Nx monorepos so product squads move faster with fewer one-offs. Through Msassi Design+Code Ltd., I run contract engagements while delivering as a senior individual contributor.
