Sarah Chen
Full-Stack Developer & Technical Writer
I build things for the web and write about what I learn along the way. With over a decade of experience spanning frontend frameworks, backend systems, and everything in between, I created DevPulse to share practical, no-fluff insights that help developers ship better software.
When I'm not coding or writing, you'll find me contributing to open source, mentoring junior developers, or exploring the latest browser APIs. I believe the best technical content is honest, opinionated, and rooted in real production experience.
