Yohann Paris
Senior web developer from the French Alps.
I build web applications, data visualisations, and software for people who need clear, useful tools.
Over the past 20+ years, I have worked across Canada, the United States, Switzerland, and France on a mix of
platforms, products, and interactive experiences. I like projects that combine solid engineering, thoughtful
interfaces, and close collaboration with the people using them. Native French speaker, I'm also fluent in English.
Selected Work
A few projects that show the range of the work: product development, data storytelling, and long-running
platforms.
Terarium
A large open-source platform where I worked across backend services, front-end applications, and
infrastructure.
Worked across APIs, UI components, data flows, and deployment.
Helped shape a product used by researchers and engineers across multiple institutions.
Contributed heavily to the Open-source codebase and to the day-to-day technical direction.
Atlantis
A platform for exploring and managing large collections of technical information.
Worked on ingestion, search, metadata, and the front-end experience.
Helped turn a messy information space into something more navigable and useful.
Built pieces across backend services, front-end code, and supporting tools.
Brookings Institution
Public-facing interactive work where the challenge was making complex ideas clear and engaging.
Created more than 30 interactive publications in JavaScript, D3, and Mapbox.
Took ownership of analytics infrastructure with BigQuery, Google Analytics, and Google Tag
Manager.
Work was featured by the New York Times, CNN, and the Washington Post.
Earlier Foundations
Earlier in my career, I worked directly with clients on custom applications and learned a lot from
small teams and hands-on delivery.
Built a custom inventory system at The Metrick System that saved a client roughly $50,000 per year.
Worked on backend development and testing during internships in France and Switzerland.
Built the habits that still matter most to me: clear code, good structure, and respect for users.
What I Bring
I am at my best when a project needs both hands-on implementation and a broader view of how the
whole thing should fit together.
Working with people
Comfortable working with clients, researchers, stakeholders, and teammates from idea to
delivery.
Front-end and interaction
I care about interfaces, readability, and making complex ideas feel approachable.
Full-stack development
Comfortable moving between front-end, backend, databases, APIs, and deployment.
Product thinking
I like turning rough requirements into clear decisions and practical software.
