Description

I am a Full Stack Developer specializing in PrestaShop and e-commerce, focused on improving online stores, automating processes, and developing custom functionalities for businesses that want to sell more and work better.

I primarily work with PrestaShop 8/9, PHP, MySQL, JavaScript, and external APIs. I develop custom modules, integrations with Google Merchant Center, Google Ads, OAuth2, stock systems, automations, and improvements in both front-office and back-office.

I have worked on stores with over 1,000 products, optimizing performance, technical SEO, and user experience. I also perform maintenance, bug fixing, visual improvements, speed optimization, and removal of unnecessary module dependencies.

In addition to PrestaShop, I have experience as a Full Stack Developer with Next.js, Node.js, and Supabase, which allows me to create more modern solutions and advanced integrations when the project requires it.

Services I usually offer:

• Custom PrestaShop module development

• Bug fixing and maintenance

• Speed optimization and Core Web Vitals

• Integrations with APIs and external services

• Google Merchant Center and product feeds

• Customization of checkout, login, and purchase processes

• Technical SEO for e-commerce

• Automation of internal tasks and processes

I like to work with clear communication, practical solutions, and maintainable code designed for real production projects.
