Hi, I'm Sudhanshu Ranjan. I'm a senior frontend engineer with 6+ years of experience building fast, responsive, accessible products. I focus on frontend architecture, cross-browser behavior, and shipping features end-to-end with product, design, and backend teams. Outside of work, I enjoy video games, anime, and reading.

Ask me about iframes or forms — I've solved my fair share of tricky problems there.

I'm currently working as a senior software engineer (frontend lead) at Fletch.

I like learning new things and sharing my knowledge with others.

For a detailed overview, you can download my resume.
