About
I am Sylvain Liagre, a C# / Unity developer with 14 years of experience in creating real-time 3D applications for PC, VR, mobile, and the Web. My dual background in development and 2D/3D graphics allows me to handle a project from end to end, from requirements definition and software architecture to development, asset creation, and support during delivery.
I design robust, optimized, and sustainable systems, with particular attention to performance, code clarity, and visual quality. I also enjoy developing Unity Editor tools and automation solutions to reduce production time and improve the consistency of deliverables.
My rigor, proactivity, and team-oriented mindset enable me to collaborate effectively within multidisciplinary teams (3D artists, developers, freelancers) and to anticipate technical and functional needs. I have contributed to large-scale projects such as the Grand Paris Express and bids for the Paris 2024 Olympic Games.
