About Diego

Ayudo a empresas, startups y equipos técnicos a construir, modernizar y mantener aplicaciones web, APIs, dashboards, automatizaciones e integraciones a medida.

Soy Diego, Senior Full Stack Developer con más de 6 años de experiencia profesional en desarrollo de software. Actualmente trabajo en Ohtic Solutions, donde participo en proyectos de backend, frontend, cloud, automatización, ecommerce, CMS, integraciones y soluciones con inteligencia artificial.

Puedo ayudarte en proyectos como:

  • Desarrollo backend con PHP, Laravel, Symfony, Phalcon, .NET, Node.js y APIs REST.
  • Desarrollo frontend con React, Next.js, Vue, Angular, TypeScript, Tailwind y Bootstrap.
  • Integraciones con Stripe, PayPal, Shopify, HubSpot, Google APIs, SendGrid, SAP y servicios externos.
  • Automatización de procesos, asistentes con IA, OpenAI, LangSmith, Jira, Confluence y flujos RAG.
  • Dashboards, paneles administrativos, herramientas internas y plataformas SaaS.
  • WordPress, Shopify, Drupal, CMS personalizados y ecommerce.
  • Bases de datos MySQL, PostgreSQL, SQL Server, MongoDB y Redis.
  • Docker, AWS, CI/CD, despliegues, mantenimiento, debugging y mejora de rendimiento.

Me diferencio por tener una visión full stack real: puedo entender la necesidad del negocio, diseñar una solución técnica clara y llevarla a producción con código mantenible, documentación, pruebas y buenas prácticas.

Si necesitas una solución estable, escalable y bien estructurada, puedo ayudarte desde el análisis inicial hasta la entrega final.
