    Sunnat says,

    Muhammad is a top-tier professional. He didn’t just deploy a standard Dolibarr ERP for my heating and climate control business (SR Lux); he built a sophisticated, custom-tailored ecosystem. Key highlights of his work: Custom Modules: He developed a complex 'Landed Costs' module that automates shipping/customs calculations by volume and value, and an 'Investor Equity' module for real-time profit sharing. Warehouse Automation: Built a barcode management system with duplicate-blocking and mobile scanner integration. AWS Expertise: Fully configured the cloud infrastructure (AWS EC2), secured it with SSL, and set up automated daily backups. Business Logic: He deeply understood our workflow, separating access levels for administrators, sales, and warehouse staff perfectly. If you need someone who understands both high-level coding and real business processes, Muhammad is your guy. Highly recommended!
