Hi, I’m Ashfahan Khan, a founding Senior Full Stack Engineer and AI-powered product developer with 8+ years of experience delivering scalable frontend and backend systems. I design modern architectures using React, Next.js, Vue, Svelte, Node.js, and TypeScript, focusing on reusable components, robust data models, and delightful user experiences.
I’m a collaborative leader who mentors junior developers, champions accessibility and design systems, and loves solving hard problems with a user-first mindset. When I’m not coding, I enjoy exploring new AI tooling, building cross-functional partnerships, and sharing knowledge with my team.
