About Léo

I am an independent developer specializing in creating high-performance digital products. My website showcases all my projects.

My role is at the intersection of code, design, and business strategy. I am involved in the entire project lifecycle to transform a vision or raw need into a scalable, intuitive, and market-ready product.
My goal is not just to write lines of code, but to provide end-to-end support to launch your product (Mobile Applications, SaaS, Web Platforms).

My key skills & responsibilities:

Product Scoping & Strategy: In-depth analysis of your needs, active participation in developing specifications, and clear commercial proposals (costing, technical feasibility, architecture).

Design & UX/UI: Design of modern, clean, and user-centered interfaces. I ensure the customer journey is smooth to guarantee maximum adoption of the application.

Fullstack Architecture & Development: Focus on robust and tailor-made technological choices. I develop high-performance cross-platform solutions, particularly leveraging Flutter for the frontend (mobile/web) and Go for solid, ultra-fast backends.

Client Relations & Project Management: I am your primary point of contact. I ensure transparent communication throughout development, strict deliverable management, and guide you through change management.

How do I work?

I make it a point of honor to make you autonomous once the product is delivered (through training, documentation, or personalized video tutorials). Always keeping up with technological advancements, I integrate the best tools and latest innovations to offer you a cutting-edge product.

Let's discuss your project and build together the solution that will grow your business!
