Emmanuel Roussel

Developer, Designer & Entrepreneur

I'm a software developer from Québec, Canada currently living in Seoul, Korea. I'm the co-founder of Berna, a startup improving the quality and efficiency of health care in Sub-Saharan Africa by digitizing medical records.

I'm an optimist who believes things can be better than they currently are. Phrases like "because it's always been done this way" are not part of my vocabulary – I instead value open-mindedness and outside-the-box thinking.

While most of my experience building digital products is in software engineering, I also think and care a lot about the end users. I love empathizing with them, creating designs, and anything that will ultimately help deliver real value to them. This includes all aspects of the user experience (not only the actual design but also accessibility, performance, etc.). The web should be delightful for everyone to use.

With a strong attention to detail, product mindset, and design sense, I'm at my best when working in small independent and collaborative teams solving tangible problems (usually at smaller organizations where I can have a greater impact) or as a startup founder. I'm a fast learner who's not afraid to get his hands dirty and wear multiple hats.

On the practical side, most of my experience is in building and designing web applications using JavaScript, React, Next.js, and GraphQL. I've also led teams, architected new projects, built accessible component libraries, internationalized codebases, and mentored developers.
