Saabbir Hossain

Sr. Frontend Engineer | CRO & A/B Testing


Hi there 👋

I'm an Optimizely-certified CRO (A/B testing) developer and veteran frontend engineer
with a passion for writing high-quality code and delivering bug-free tests.

I bring 8 years of experience building high-quality, performant websites and apps
using modern tools like React and Shopify.

In the past 3 years, I've specialized in CRO and A/B testing, helping e-commerce sites
overcome user friction and drive revenue growth through targeted optimization.

My code adapts beautifully across devices, ensuring flawless user experiences.


A/B testing tools I use regularly:

✅ Optimizely
✅ VWO
✅ Convert
✅ AB Tasty
✅ Adobe Target
✅ Dynamic Yield
✅ Kameleoon


Looking for projects involving:

✔️ Frontend development (HTML, CSS, JavaScript, React)
✔️ A/B testing and CRO strategy (Optimizely, AB Tasty, Convert, VWO, etc.)
✔️ Shopify development


Some cool stats about me:

🔥 I have successfully developed more than 200+ a/b testing ideas.
🔭 I’m currently working with React, Shopify, and CRO Development.
🌱 I’m currently learning about Full-Stack Web Development.
🏆 I'm a Top Rated freelancer at Upwork.
👯 I’m looking to collaborate on freelance projects.
⚡ Fun fact: I love Vanilla JS 💜
