Site Positioning & Core Content

This is the personal portfolio blog of Jessica Pagán Sánchez, a senior design systems engineer at Microsoft. The site centers on two core topics: building design systems and AI-assisted product design + prototyping, showcasing the author's professional experience, project outcomes and in-depth thinking. Currently, the public content on the site includes the author's project experience leading the SharePoint design system build at Microsoft, plus a complete case study of AI-assisted interactive prototype development that walks through the full process of building a floating physics-effect player card prototype using Claude.

Core Value & User Experience

The site stands out for its high-quality content. Unlike generic popular science content about AI design, the author is a frontline practitioner with both design and engineering backgrounds, and fully documents the issues, trial-and-error process and final takeaways from 17 rounds of prototype iteration. She puts forward actionable practical conclusions such as visual prompts are more efficient than text descriptions and focusing on specific problems is more effective than full generation, which are extremely insightful for practitioners currently focused on AI design tools. The site uses a minimal personal blog layout, loads quickly, has no ads, and offers a smooth reading experience.

Pros, Cons & Target Audience

• Pros: Extremely high professional depth, authentic documentation of real-world work processes, and far higher reference value than most generic industry-wide shares
• Cons: It is only a non-commercial personal blog, does not offer any public products or services, content update frequency is not guaranteed, and there are no interactive features

This site is great for UI/UX designers, front-end engineers, design systems practitioners, and AI-assisted design researchers to visit and learn from. Users in mainland China can access it directly without any additional tools.
