Back to original languageAbout Jatniel
Senior PHP developer with 20 years of experience, I work on backend, e-commerce, and web application projects using Symfony, Laravel, and PrestaShop.
I support startups, SMEs, agencies, and e-commerce businesses with existing system takeover, evolutionary maintenance, technical redesign, new feature development, REST APIs, third-party integrations, and performance optimization.
My core expertise: PHP, Symfony, Laravel, PrestaShop, REST API, MySQL/PostgreSQL, Docker, and Linux.
I have extensive experience with PrestaShop: custom modules, themes/templates, catalog imports, supplier connectors, ERP/CRM/marketplace synchronization, and product journey optimization.
On Laravel and Symfony, I work on the backend: architecture, services, controllers, models, webhooks, Stripe integrations, caching, migrations, fixtures, SQL optimization, and stabilization of existing platforms.
I can also work on the front-end when the project requires it: JavaScript, TypeScript, Alpine.js, Tailwind CSS, Livewire, Vue.js, or React depending on the existing stack.
Some benchmarks:
- +20% conversion after redesigning PrestaShop product pages.
- -25% rendering time after front-end and asset optimization.
- Automation of catalog imports for tens of thousands of products.
Available remotely, with possible travel depending on the project.
