Christina Lindner, 41, is an independent UX researcher based in Berlin, Germany, holding a PhD in Human-Computer Interaction. Her career path has been driven by a desire for intellectual autonomy and a commitment to evidence-based practice. After completing her doctorate, she transitioned from academia to consulting, recognizing the direct impact her research could have on digital product development. For the past eight years, she has built a successful freelance practice, specializing in qualitative user research for software companies. Her professional life is characterized by meticulous organization; she relies on a combination of tools to manage her workflow: spreadsheets for interview scheduling and participant tracking, Obsidian for detailed note-taking and thematic analysis of transcripts, and Google Drive for storing and sharing final deliverables. This system allows her to maintain precision and accessibility across projects. She frequently collaborates with two trusted contractors, typically a qualitative analyst and a report designer, on recurring projects, ensuring a consistent quality of output. Christina's income of €74k reflects her expertise and the value she brings to clients, though she remains mindful of financial prudence, reinvesting in her professional development and reliable tools. She is driven by a core set of values: the pursuit of evidence, unwavering precision in her findings, and fostering deep client trust through transparent and rigorous work. Her decision to remain independent stems from a strong preference for autonomy and the ability to select projects that align with her research interests, such as exploring the nuances of knowledge management systems and digital organization tools. She recently decided to refine her onboarding process for new clients, aiming to set clearer expectations from the outset and further solidify the trust that underpins her business.

  1. What would stop you from trying Bookmark OS (https://bookmarkos.com/) this month? Be specific about how you handle this today. Also say the maximum you would pay per month in USD (0 if nothing).

    My current workflow is quite established, using Obsidian for my detailed transcript notes and spreadsheets for interview links. While the idea of an all-in-one solution like Bookmark OS is appealing, especially the tab and bookmark management, I'm concerned about integrating it with my existing Obsidian system and ensuring the data remains accessible long-term. The administrative overhead of potentially moving and organizing everything gives me pause. I'd be willing to pay up to $10 per month, provided it integrates seamlessly and doesn't create more work.
