About Muntasir Mahmud
I help e-commerce brands and agencies build, scale, and rescue high-performing WordPress, WooCommerce, and Shopify stores, and I bring modern AI capability to each one. If your store needs to move faster, convert better, or stay visible as shopping shifts toward AI assistants, that's exactly where I work.
With 15 years in the ecosystem and a top 3% Codeable ranking across 680+ delivered projects at a sustained 4.95/5 rating, I've earned the trust of law firms, publishers, NGOs, and online retailers worldwide. I'm also a WordPress Core Contributor (credited across versions 5.0 to 6.1) and the founding engineer behind Exclusive Addons for Elementor, which I grew to 60,000+ active installations before its commercial acquisition.
What makes me different is the combination of deep platform engineering and real product experience. I don't just patch sites; I architect them, ship commercial software, and understand what makes a store perform. As a published Shopify app developer (Darkify, StockPulse, Seasonify, built with Remix and Next.js) and a Zend Certified Engineer, I bring the discipline of product-grade code to every client engagement.
Projects I typically handle:
- Platform and CMS migrations (including legacy systems to WordPress or Shopify) with zero downtime
- Custom WooCommerce and Shopify builds, including multivendor marketplaces and subscription systems
- Security audits, performance optimisation, and rescue work on inherited or broken codebases
- Custom plugin, theme, and app development
- AI integration: LLM and RAG-powered features such as conversational product search, support automation, and product data enrichment
I work cleanly, communicate clearly, and deliver on the dates I commit to. Whether you need a one-off build, a complex migration, or an ongoing development partner, I'll treat your store like the revenue engine it is.
Let's build something that performs.
