About
The personbehind the work
Youssef AserrarEngineering manager · Full-stack & mobile engineerI'm Youssef, a software engineer from Casablanca. For five years I've taken web and mobile products from the spec to production: the interface, the API, the database and the deploy.
Today I lead a team of developers, and I still step into the code when a project needs it. I care about products that are fast, clear and honest about what they do.
