About Juan Jesús

PHP Symfony Developer Engineer.

With over 14 years of experience, I support companies in the design and development of high-performance and scalable web solutions. Symfony Backend Specialist, I have in-depth expertise in software architecture, REST APIs, security (JWT, GDPR), and SEO optimization.

I have worked on SaaS projects in the hotel and tourism sector, particularly with Rommy App, an innovative digital welcome booklet, as well as on ERPs, After-Sales Services (SAVs), Cybersecurity, and B2B platforms requiring a robust and scalable technical approach.

My expertise:

✅ Symfony Development (versions 4.4 - 6.4) with a DDD and Clean Architecture approach
✅ Security and authentication (JWT, OAuth, access management, GDPR)
✅ API integration and interoperability (OpenAI, Google Finance, TinyMCE, A2lix, etc.)
✅ UX/UI and technical SEO optimization
✅ Automation & DevOps (CI/CD, Docker, VPS hosting, n8n)

My approach is centered on performance, scalability, and ease of use. I also support my clients in their digital strategy and the optimization of their tools to maximize their impact.

Available for freelance missions: technical audit, product management, assessment, custom development, platform redesign, PHP or Symfony migration, API integration, security, testing, and much more.
