Back to original languageAbout Pablo
Senior Symfony Developer (9 years of experience, ex-Technical Director at an agency), I provide backend support to agencies and product teams on long-term assignments.
I work as an integrated developer within your team: autonomous, quick to grasp an existing codebase, and delivery-oriented.
Objective: to advance your product frictionlessly, without technical debt, and without the need for micro-management.
I typically work on:
- Symfony backend development (features, product evolutions)
- API design and evolution (business applications, SaaS)
- Stabilizing applications in production (bugs, technical debt)
- Refactoring and improving existing code
- Performance optimization
My working method is as follows:
- Quick understanding of the business and challenges
- Clean, maintainable, and team-exploitable code
- Direct and effective communication
- Respect for deadlines and commitments
6 years in agencies (developer, project manager then technical director), then freelance.
I am used to working on projects already in production with challenges related to stability, scalability, and speed of execution.
Types of assignments:
- Symfony team reinforcement for several months
- SaaS development and evolution
- Complex business applications
I prefer long-term collaborations with structured teams.
Stack: Symfony, PHP, API, MySQL, PostgreSQL, Docker, Git, GitLab, Vue.js, JavaScript
If you are looking for a Symfony developer who can integrate quickly and produce effectively over time, you can contact me.

Excellent service delivered very quickly. We were in continuous contact to deal with an emergency: our host had migrated to PHP8 and our WordPress sites were no longer working. Pablo was responsive and very competent.
Recommended for his seriousness and expertise.

Pablo assists us in the web development of our SaaS software. We work together on several topics: tool architecture, adding new features, and improving existing ones.
What we particularly appreciate are his technical and very advanced skills in several languages, as well as his ability to understand our business and thus have a medium-to-long-term vision in the technical choices we make together.
I recommend this freelancer 100%.
