Dhaval Balar.
India-based CRO & A/B testing developer. I engineer high-conversion experiments on Webflow, HubSpot, Marketo and Instapage — building CMS experiences that move real numbers.
The person behind
the experiments.
I'm a CRO and A/B testing developer based in Surat, Gujarat — turning hypotheses into measurable conversion lifts for marketing teams across the globe.
My focus is the messy middle of the funnel: building, debugging and shipping experiments inside enterprise CMS platforms. I treat performance, accessibility and code clarity as features, not afterthoughts.
Currently leading experimentation engineering at Spiralyze.
