Hire the Best PHP Developers
in Argentina

Hi, I'm Josh. I've been working with WordPress and PHP for 15+ years. I mostly help with technical fixes, custom plugins, WooCommerce checkout or payment issues, API integrations, Elementor cleanup, and performance work. I'm not an agency. I like to understand the actual problem, explain what's going on, fix it carefully, and keep things simple.

Top Rated Full-Stack Developer with 10+ years of experience building web and mobile applications. 48+ completed projects on Upwork. I specialize in three stacks where I deliver the most value: - Backend & APIs with PHP (Laravel, Symfony, CodeIgniter) - clean, scalable, well-documented code. - Frontend & SPAs with Angular - dashboards, admin panels, and complex business applications. - Cross-platform mobile apps with Ionic, Flutter and React Native - iOS and Android, with Firebase, push notifications, and social login. What clients tell me they value most: - I ship on time and communicate clearly. No surprises, no excuses. - I think like a systems analyst, not just a coder - I ask the right questions before writing code, which saves you time and money. - I write maintainable code your next developer won't curse at. - Bilingual: fluent in English and Spanish, so communication is never a bottleneck. I also work with Node.js (Express, REST APIs, JWT), WordPress (custom themes and plugins), C#/.NET, and databases like MySQL, PostgreSQL, SQL Server, MongoDB, and Firebase. Whether you need a new app built from scratch, an existing system improved, or a developer who can take ownership of a project end-to-end - I can help. Send me a message with a few details about your project and I'll reply within a few hours with honest feedback on scope, timeline, and how I'd approach it.
