Background & daily life

A day in their life

Sarah's typical weekday begins around 7:30 AM with coffee and a quick scan of design news. She commutes to the office by 9:00 AM, often using the time to listen to a podcast. Her morning is usually dedicated to focused design work in Figma, iterating on dashboard mockups or refining components. Around 11:00 AM, she has a sync with her developer to review recent progress and discuss upcoming tasks. Lunch is a quick, healthy meal, sometimes eaten at her desk while catching up on emails. The afternoon involves more design sessions, perhaps a stakeholder meeting to gather feedback, or working on a React prototype. She aims to wrap up by 6:00 PM, heading home for dinner and personal time, which might include reading or planning her next design exploration.

Lifestyle

Sarah lives a structured but not rigid life in her Prenzlauer Berg apartment. She values her quiet mornings with coffee and a book before heading to the office, or working from home.
