About Alexandre

Do you have a web or mobile project and are you looking for someone who understands your business needs as well as the technical constraints? That's exactly what I bring.

Graduated full-stack engineer and IT business engineer for several years with major clients, I am the freelance who bridges the gap between your ideas and their concrete realization. No need to explain everything to me in technical terms — I know how to frame a project, anticipate risks, and deliver what was agreed upon.

What sets me apart: I'm not just a developer. I've sold and managed complex IT projects from a consulting perspective. I know the cost of a bad statement of work and how to avoid it. I work on a fixed-price basis for complete projects: showcase websites, business web platforms, iOS/Android mobile applications. From defining the need to putting it into production.
