About Valentin

Developer with 5+ years of experience, I design and deploy complex business-oriented web applications (SaaS, CRM, Database Management).

My goal: transform your business rules into a robust, scalable, and production-ready application.
As a specialist in MVP launches, I combine the power of Laravel and the fluidity of React with Inertia.js to deliver high-performance 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). Full 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 that leaves my hands is monitored, tested, and deployed via an automated CI/CD pipeline. No surprises in production.
