Hi! I'm Ruan, a product-minded developer with over 11 years of experience. I’ve also done plenty of design and product management without ever holding the title.

I build web applications that make sense, look good, and perform well.

As a freelancer, I work with early-stage companies and founders – either building products from scratch, or leveling-up their existing ones. Through experience and pragmatism, I help them move the needle on real business goals.

I’m an expert at React, Next.js, Astro, and Node.js. I have desgined, built, and maintained dozens of applications with these technologies. I often write about them on my blog .

"What makes Ruan stand out is that he actually cares about the work he does. He wants each line of code to be his best work. Not in a I'll-take-my-own-sweet-time kind of way. But in a I-want-to-help-the-business-succeed kind of way."
