I had the pleasure of working with Muhammad as part of our engineering team at Automattic, where we were heavily focused on developing and optimizing the performance of a WooCommerce Marketplace backend.

Muhammad played a key role in identifying and resolving complex performance bottlenecks in our WooCommerce-based system. He has a strong understanding of how WordPress and WooCommerce work under the hood — from database structure to plugin management, background jobs, and scaling challenges in high-traffic environments.

Muhammad was directly involved in developing core WooCommerce APIs related to plugin installation and update flows. Working at this level gave him deep insight into WooCommerce internals, including security considerations, update mechanisms, and how large-scale marketplace reliably manages hundreds of thousands connected stores.

During our marketplace performance initiatives, Muhammad consistently approached problems methodically: profiling slow requests, analyzing database queries, refactoring inefficient logic, and implementing measurable optimizations that significantly improved response times and system stability. He doesn’t just apply quick fixes — he looks for root causes and long-term solutions.

What stands out most is his ability to work with real-world WooCommerce stores where performance issues are rarely isolated. If you’re running a WooCommerce store and struggling with speed, scalability, or backend performance issues, Muhammad is someone I would confidently recommend.
