Co-founder and CTO then COO of Internest for 5 years, I am now Freelance to bring my expertise as a project manager and multitasking and multi-skilled developer to technical and innovative projects.
I have already brought several products from the idea stage to commercialization, including that of Internest where we developed an autonomous landing system for drones (design of the electronics, but also of the embedded code for military and aeronautical applications) or even an interactive work of art in Minneapolis.
My experiences are mainly in embedded C++ (creation of libraries, object-oriented code...), in electronics and rapid prototyping, but my background has led me to touch on other languages (Python, JavaScript, Angular...).
I work very well in a team (I have managed several) and I think I am very rigorous, pragmatic and efficient which allows me to quickly appropriate a subject while providing quality work and deliverables.
For 3 years, I have been collaborating with other freelancers within Qastor to be able to support our clients from a blank sheet to the development of their product.
