Hi, I'm Saabbir Hossain — Sr. Software Engineer at EchoLogyx Ltd with 8+ years of experience leading Shopify Plus storefront development, 200+ Optimizely/A/B experiments, and high-performance frontend architecture.

Endorsements from engineering directors, enterprise CRO strategists, and SaaS CEOs who have managed Saabbir directly.
Saabbir is one of the best, if not THE best, developers I have ever had the pleasure of working with in my career. I recently worked with him on a large enterprise client, and he was a MAJOR reason for their testing success. He's unbelievably fast, super knowledgable, proactive, lovely to work with, and always found solutions for anything that came up. Anyone that gets to have Saabbir on their team is very lucky!
Saabbir has been an integral part of our development operations. Despite being remote with very different timezone, he's been very capable of adapting and integrating into our US-based operations. Very creative, prompt, and skilled.
Saabbir delivered pixel-perfect HTML/SCSS site templates for our digital location platform ahead of schedule. His modular BEM code structure and attention to detail were outstanding.
