About Diego

I help companies, startups, and technical teams build, modernize, and maintain custom web applications, APIs, dashboards, automations, and integrations.

I'm Diego, a Senior Full Stack Developer with over 6 years of professional software development experience. I currently work at Ohtic Solutions, where I participate in projects involving backend, frontend, cloud, automation, e-commerce, CMS, integrations, and artificial intelligence solutions.

I can help you with projects such as:

  • Backend development with PHP, Laravel, Symfony, Phalcon, .NET, Node.js, and REST APIs.
  • Frontend development with React, Next.js, Vue, Angular, TypeScript, Tailwind, and Bootstrap.
  • Integrations with Stripe, PayPal, Shopify, HubSpot, Google APIs, SendGrid, SAP, and external services.
  • Process automation, AI assistants, OpenAI, LangSmith, Jira, Confluence, and RAG flows.
  • Dashboards, admin panels, internal tools, and SaaS platforms.
  • WordPress, Shopify, Drupal, custom CMS, and e-commerce.
  • Databases like MySQL, PostgreSQL, SQL Server, MongoDB, and Redis.
  • Docker, AWS, CI/CD, deployments, maintenance, debugging, and performance optimization.

I differentiate myself by having a real full-stack vision: I can understand business needs, design a clear technical solution, and deliver it to production with maintainable code, documentation, tests, and best practices.

If you need a stable, scalable, and well-structured solution, I can help you from the initial analysis to the final delivery.
