About Valentin

Developer with 5+ years of freelance experience, I design and deploy complex web applications (SaaS, CRM, Database Management) oriented towards business needs. My goal: transform your business rules into a robust, scalable, and production-ready application. Specialist in MVP launches, I combine the power of Laravel and the fluidity of React with Inertia.js to deliver ultra-performant products in record time, without the warm-up of a classic API/SPA architecture.

🛠️ Technical Stack & Expertise
Backend: PHP / Laravel (Clean architecture, complex business logic, Queues, Security).
Frontend: React / Inertia.js (Fluid user experience, friction-less Single Page Application).
Data: PostgreSQL (Advanced modeling, query optimization, volume management).
DevOps / Production: Docker, CI/CD (GitHub Actions). Total automation of build, tests, and production deployment, zero downtime.

🎯 What I bring to your project:

1 Speed and Precision (MVP): Ideal for validating your market with a finished, clean, and scalable product thanks to the Laravel + Inertia + React combo.

2 Strict Business Logic: Ability to model complex workflows and critical data management systems.

3 Full Production Culture: Everything I deliver is monitored, tested, and deployed via an automated CI/CD pipeline. No surprises in production.
