PrestaShop Bug Fix & Module Developer

May 2024 - Present2 yrs 2 mos

I provide advanced PrestaShop bug fixing and custom module development services to resolve complex issues affecting ecommerce store performance and functionality. My expertise includes identifying and fixing critical errors such as 500 internal server errors, white screen issues, checkout failures, cart bugs, payment gateway problems, and module conflicts. I carefully debug PHP, SQL, JavaScript, and theme-related issues to ensure stable store performance. In addition to bug fixing, I develop and customize PrestaShop modules based on business requirements. This includes modifying existing modules, creating new features, and integrating third-party APIs to extend store functionality. I also handle theme-related issues such as layout breaking, CSS/JS conflicts, and compatibility problems after updates or upgrades. Every fix is tested thoroughly on staging or live environments to ensure stability without affecting sales operations. I focus on long-term solutions, not temporary fixes. ✔ PrestaShop error & bug fixing ✔ Module development & customization ✔ Checkout & payment issue resolution ✔ Theme & UI bug fixing ✔ API integration & performance stability

PrestaShop Migration & Upgrade Specialist

May 2023 - Present3 yrs 2 mos

I specialize in safe and professional PrestaShop migration, upgrade, cloning, and backup services, ensuring zero data loss and minimal downtime during transitions. I handle migration of PrestaShop stores from one hosting provider to another, including full database transfer, file migration, and server configuration. I also perform version upgrades from older PrestaShop versions (1.6, 1.7) to newer versions (8.x, 9.x) while maintaining full compatibility. My process includes creating full backups before any operation, cloning stores for testing environments, and fixing post-migration issues such as broken themes, module incompatibilities, and database errors. I ensure that all products, customers, orders, and SEO URLs remain intact after migration. I also reconfigure SSL certificates, domain settings, and server environments to ensure smooth operation. Every migration is tested thoroughly before final deployment to avoid downtime and ensure business continuity. ✔ PrestaShop migration & server transfer ✔ Safe upgrade (no data loss) ✔ Store cloning & backup setup ✔ Post-migration bug fixing ✔ SEO & database integrity protection
