About Jérémy

Freelance web developer, I specialize in creating tailor-made digital solutions designed to optimize internal processes, improve operational efficiency, and directly contribute to business performance. My approach is based on a keen understanding of business challenges before the technical aspects: I design useful tools, conceived to simplify daily tasks, structure workflows, automate repetitive tasks, and enable teams to focus on what truly creates value.

I have developed solid expertise in building CRMs, internal tools, business applications, e-commerce platforms, and showcase websites for startups, SMEs, and established companies. I am involved in the entire project lifecycle: scoping, technical choices, architecture, development, performance, security, deployment, and maintenance.

I create solutions adapted to real needs: lead and customer management, dashboards, reporting, automation, collaborative tools, third-party integrations, SaaS systems, professional web platforms, high-performance e-commerce, and showcase websites focused on conversion and brand image.

Beyond the interface, I design robust and scalable backends, ensuring performance, security, scalability, and reliability. My core technologies: Next.js, React, Node.js, Express, PostgreSQL, Firestore, Cloudinary, Laravel, Symfony.

I favor transparent, results-oriented collaboration, with clean, maintainable code and clear communication. My objective remains the same: to create sustainable solutions that generate value, productivity, and performance for companies looking to go beyond generic tools.
