Senior WordPress engineer. 15+ years building, maintaining and contributing to the platform itself. Most WordPress problems are not coding problems. They are decisions made early by someone who did not know what the site would eventually need to do. I am hired by clients who want those decisions made correctly the first time: businesses building something custom, agencies needing a senior pair of hands, and site owners who have outgrown plugins and page builders. I am as involved in scoping a project as in delivering it, and I will tell you when a simpler approach serves you better. Credentials behind that judgement: ✔ Serial WordPress Core Contributor: 5.0, 5.0.2, 5.0.3 and 6.1. I do not just build on WordPress, I help build WordPress. ✔ Founder & CTO of Exclusive Addons for Elementor, live on 50,000+ sites. I own the architecture, releases and support of code thousands of businesses rely on. ✔ WordCamp organiser, official theme and plugin developer, Zend Certified Engineer. Where I am strongest: ✔ Custom theme and plugin architecture built to survive core updates ✔ Full website builds from specification through launch ✔ Custom Elementor widgets and Gutenberg blocks with React JS ✔ WooCommerce development, integration and scaling ✔ Deep customisation of themes and plugins without locking you in ✔ API integrations and headless builds on the WP REST API ✔ Performance engineering, security hardening, PHP migrations ✔ Shopify development alongside WordPress ✔ PHP, JavaScript, React JS, jQuery, Ajax, HTML, CSS, MySQL How I work. You get a clear plan before I write code: what I will change, what could go wrong, and how I will protect what already works. I build on staging, document what I hand over, and explain trade-offs in language you can act on. My career began in customer support before it turned technical, which is why clients say communication matters as much as code. If you have a project that has to be right, let's scope it properly.

Muntasir is an exceptional developer. I hired him to fix a critical emergency after a previous developer broke my website. His expertise and professionalism were a breath of fresh air. His communication was clear, his plan was detailed and safe, and he executed the complex fix perfectly. He even went above and beyond by fixing an extra bug and providing strategic advice for my site's future.

Muntasir did a great job fixing issues during the upgrade from PHP 7.4 to 8.4 on our website. We had custom Themes and plugins that were outdated. He gave a good explanation of what had to be done and the plan to fix it. He carried out the plan and finished earlier than the deadline. I am planning to do more work for us.

Muntasir has completed phase 1 of our project, and he has been an absolute pleasure to work with. He's responsive, takes the time to understand the vision, and communicates clearly throughout the process. He's also been very patient as we've worked through requirements together. I'm really looking forward to continuing our partnership through the remaining phases!
