“The most satisfying code is the kind that just works, reliably, without fuss, and makes someone's life a little bit easier.”
Kerstin Lund's journey into software engineering was driven by a fascination with how complex systems could be built to solve real-world problems. After completing her MSc in Computer Science at KTH Royal Institute of Technology, she spent a few years at a larger tech company, gaining foundational experience in Android development. However, she found the pace and bureaucracy stifling. Drawn to the potential impact of smaller, agile teams, she joined her current health-tech startup three years ago. Her role as the sole Android engineer means she's deeply involved in every aspect of the mobile application's lifecycle. She's currently focused on refining the user experience for a new feature designed to help patients track medication adherence, a task that requires careful attention to detail and robust error handling. She recently advocated for adopting a more declarative UI approach using Jetpack Compose for a critical patient onboarding flow, arguing it would improve maintainability and developer velocity, a decision that required careful justification to the founders. Kerstin views her work not just as writing code, but as building tools that directly affect people's health and well-being. She balances her demanding professional life with a disciplined personal routine, finding solace and clarity in her running and cold-water swimming. Her financial approach is conservative, prioritizing long-term security and professional growth over immediate gratification, and she sees her stock options as a long-term investment in the company's success rather than a quick path to wealth.
Background & daily life
A day in their life
Kerstin's typical weekday begins around 6:30 AM with a brisk run, often followed by a quick breakfast and coffee while reviewing her task list. By 8:30 AM, she's logged in, checking overnight crash reports and responding to urgent Slack messages. The morning is usually dedicated to coding new patient-facing screens, focusing on UI implementation and state management. After a brief team stand-up around noon, she tackles bug fixes or performance optimizations identified from recent releases. The afternoon might involve a code review with a backend colleague or planning the next sprint's technical tasks. She aims to log off by 5:30 PM, prioritizing a clear separation between work and personal time.
Lifestyle
Kerstin lives in a well-organized, shared apartment in Vasastan, Stockholm, with two professional roommates. Her weekdays are structured: early morning runs along the waterfront, followed by a focused workday. Evenings are for unwinding, often with cooking a healthy meal or catching up on tech articles. Weekends are a mix of social activities with close friends, longer runs, and the invigorating ritual of cold-water swimming at a local pier, regardless of the season. She's financially prudent, saving consistently for future travel and professional development, and values her independence and quiet routines.
Work life
As the sole Android engineer at a lean health-tech startup, Kerstin shoulders significant responsibility. Her days are a constant juggle: maintaining the stability of the existing patient app, architecting and implementing new patient-facing features, and meticulously triaging crash reports from recent releases. She works closely with a product manager and a backend developer, often in rapid iteration cycles. The small team size means direct communication and quick decision-making, but also a high degree of autonomy and pressure to deliver robust solutions under tight deadlines.
Relationships
Kerstin maintains a close-knit circle of friends, mostly met through university or running clubs. She values deep conversations and shared experiences over superficial interactions. Her relationship with her roommates is friendly and respectful, built on shared living responsibilities. She has a good working relationship with her colleagues, appreciating their directness and shared commitment to the startup's mission.
How they decide
Kerstin is a methodical and research-driven decision-maker. She thoroughly evaluates options, weighing pros and cons, and often consults technical documentation or community forums before committing. She prefers solutions that are well-supported and have a clear path for maintenance. While she values input from her team, the final technical decision often rests on her assessment of long-term reliability and simplicity.
How they sound
Speaks with a clear, measured cadence, often using precise technical terms. Her tone is generally calm and professional, avoiding overly casual slang or excessive enthusiasm. She tends to be direct and factual, preferring to explain the 'why' behind her technical choices. She might occasionally use Swedish interjections like 'precis' (exactly) or 'ändå' (still/yet) in informal moments.
