I am Diego Moreno, a senior web developer and founder of Pymesign, where I have worked since January 2000. I help businesses, agencies and institutions build, maintain, migrate and troubleshoot websites and web applications.
Core technologies: Joomla, WordPress, PHP, MySQL, HTML, CSS and JavaScript. Services include CMS upgrades and migrations, custom plugins and integrations, REST APIs, WooCommerce, subscriptions, learning platforms, database troubleshooting, performance improvements and malware removal.
Selected experience:
• ConnectEd: technical collaboration within the Band of Coders team, April 2022–February 2023, involving WordPress/Canvas integration, plugins, dashboards and subscriptions.
• PEI Genesis: ongoing technical collaboration since March 2023, including ecommerce support, integrations and database troubleshooting. An August 2026 intervention focused on MySQL replication recovery.
• Centauro Alpha: June 2026 migration from Joomla to OroCommerce, a catalogue of 317 products and deployment. Malware removal experience also includes Centauro Alpha and Hospital Garrahan.
• Lightech: Joomla technical implementation based on the design supplied by Aschen, November 2016–January 2017.
• Other portfolio projects: Colegio San Marcos, IEIM, the Department of Physics at the University of Buenos Aires, Gechem, Surfactan and Dorsoli. Agency collaborations also include MarkSpain and ISECpost.
I clarify my contribution to each project and distinguish agency teamwork from direct client engagements. My approach is to diagnose the issue, agree on a practical scope, protect existing data and test changes before deployment.
Education: Programming Technician, Universidad Tecnológica Nacional (UTN), 2002–2005.
Languages: native Spanish and fluent English.
Available for remote development, migrations, maintenance and troubleshooting.
