About Romain

Independent GIS web developer for 8 years, I offer development and consulting services for enhancing your geographic data through interactive web mapping tools. As a trained cartographer and geomatician, I can process your geographic data to make it perfectly compatible with web constraints in terms of volume, projection systems, and interoperability. With full-stack developer skills, I can meet many demands to create websites or tools that will allow you to exploit your data. Familiar with data manipulation, I can also meet your data visualization creation requests. Familiar with project management tools, versioning (GitHub), and Unix environments, my great versatility and curiosity can help you successfully complete your projects. Constantly monitoring OpenData, I actively participate in enriching OpenStreetMap. I also do not hesitate to share mapping visualization projects that I disseminate on my website cartosport.com.
