About Jahin Shahriar Chowdhury
Jahin Shahriar Chowdhury is a Shopify conversion rate optimisation (CRO) specialist and Funnelish template designer focused on one outcome: turning cold paid traffic into buyers. He is the founder of CRO Templates Library, a curated store of high-converting Funnelish, GemPages, Replo, and PageFly templates built specifically for DTC brands and dropshipping operators running Meta and TikTok ad campaigns.
His templates are modelled on real, proven funnels from established DTC brands — including Nooro, Try Rosabella, Koprez, Olavita, and Healthy Lab Co — and are structured around the cold traffic buyer journey: advertorial entry, product page, and post-purchase upsell. Every template is built mobile-first, fast-loading, and ready to import into Funnelish via share link within minutes.
Jahin writes about Funnelish funnel structure, paid ad conversion strategy, and Shopify CRO on the CRO Templates Library blog and publishes practical Funnelish tutorials on his YouTube channel.
