About Valentin

Full Stack Developer — WinDev / HFSQL & Modern Web Specialist

Passionate developer with 3 years of experience, I have specialized in a niche that few freelancers master: the PCSoft ecosystem (WinDev, WinDev Mobile, WebDev, HFSQL) combined with modern Web technologies.

Specifically, I work on two main areas:

PCSoft Business Applications — Design, development, and redesign of WinDev applications for specific business needs. I work on both desktop and mobile applications (Android/iOS via WinDev Mobile), with in-depth expertise in HFSQL: modeling, performance optimization, data replication, and synchronization.

Full Stack Web Development — Alongside the PCSoft universe, I design websites and web applications with current technologies: React, Node.js, Vite, PHP, as well as the integration of REST web services and third-party APIs. This dual expertise allows me to create bridges between existing WinDev applications and the Web world.

Beyond the code, I manage the accompanying infrastructure: Windows and Linux server administration, deployment, hosting, task automation, and CI/CD pipelines via Git.

What sets me apart is my constant curiosity. I continuously train myself through courses and active monitoring, particularly in artificial intelligence, which I now integrate into my daily workflow to accelerate development, automation, and complex problem-solving. AI is not a gadget for me; it's a production tool that I master and put to work for my clients.

My approach:
Clear, maintainable code, with transparent communication throughout the project.
I favor sustainable solutions over quick fixes.
Available for missions related to WinDev/HFSQL development, modern Web, automation, or modernization of existing applications.
