Abu Zaher Mohammad Bayazid

I’m a CRO Developer and A/B Testing Specialist with 5+ years of experience building and optimizing web experiments for eCommerce and SaaS companies. I specialize in vanilla JavaScript, HTML, CSS, DOM manipulation, and experimentation on modern single-page applications.

I’ve delivered 500+ A/B, multivariate, and personalization experiments across platforms such as Optimizely, VWO, Adobe Target, and AB Tasty. I enjoy turning ideas and designs into fast, responsive, and reliable web experiences while solving complex technical and UX challenges.

I’m always interested in learning new technologies, improving my craft, and building things that create measurable impact.
