Mohamed Hasan.
Leads interface design and frontend engineering across the catalog, with a focus on dense, calm operator UIs.
Design & Frontend Lead
At the studio since 2021
What Mohamed does at the studio.
Mohamed leads design and frontend engineering for the studio's products, from the payment dashboard to the after-hours queues in Northframe. The work is dense, keyboard-first interfaces that stay legible for people at the end of a long shift.
Mohamed's engineering practice treats the type system as a design tool: modelling states so illegal combinations cannot be represented, and validating data at the boundary so the rest of the code can be trusted.
Mohamed writes about interface patterns for operations, accessibility in dark rooms, and practical TypeScript for code that handles money.
