About
Engineer by craft. Founder by mindset.
Hey, I'm Zubair. I'm a full stack engineer and a SaaS founder, and I've spent the last five years building software that real businesses run on every day. The two things I really care about are code that holds up as you scale, and growth that keeps compounding instead of fizzling out.
I work with funded startups, agencies, and solo founders. I help them build SaaS products from scratch, clean up tired legacy stacks, ship Chrome extensions that actually make money, and run Google Ads that turn paid traffic into a steady pipeline.
When I'm not on client work, I'm building my own products. The WhatsApp Privacy Extension is one of them. I also write about how modern teams should treat engineering and growth as one system instead of two.
