Madam Word: Reading and Writing

Created and published a subscription-based software product that helps children overcome language learning difficulties.

Speech therapy experts designed Madam Word, a pedagogical tool that helps children overcome their language learning challenges by developing essential skills from preschool through elementary school. I conducted the whole project, from inception to release.

Teacher Support Portal

Designed and built a support portal for all Appligogiques products targeting the teachers who use them.

The Teacher Support Portal prompts the effective use of Appligogiques' applications in educational institutions. It is designed to be easy to use and quick to learn. The portal experience is centered on school or educational institution organizations and their members directly involved with the students, including teachers, educators, education professionals such as speech-language pathologists, and the administrators who invite members and manage subscriptions for the organization.

The students are grouped into classrooms. Teachers and collaborators create the classrooms and invite students to those virtual spaces. A student in a classroom has a profile name, the identifier used for logging into the apps at school and home. All the progress that students make in the games is saved online, which allows teachers and collaborators to follow up on their student's progress in real time.

Designed and engineered systems for real-time interactive visualization of immersive environments.

Space&Dream is a software engineering, design, development, and innovation agency. We commercialized digital display technologies, graphics, and interactive software for all platforms. All solutions are designed to enhance corporate communications, education, entertainment, and sales.

We were active in research and development in virtual reality and immersive environments. We brought creativity, design, and technology together to deliver innovative solutions for interactivity, display, communications, and mobility.
