Alexander Schwarzmann

Product engineer. AI interfaces & systems.

I build complex frontend products, from the initial architecture through release and ongoing development with a team. My work spans embeddable editors and shared UI platforms. Today I'm building FamilyBoon, a system for family documents and context across AI sessions.

Independent work01 / Ongoing

FamilyBoon

Family archive in use

App in development

Documents, context, and unfinished work beyond the chat.

Shared family memory / The work cycle

Each result becomes context for the next task.

Incoming A new document A letter, request, or update.
Preserved beyond any one chat Shared family record
  • Original documents
  • Matter notes and links
  • Results of previous work
Working conversation Handle the incoming task In a new chat or one already open.
Outgoing A reply or other result Saved back to the shared record.
Another conversation Read the updated record Including a chat opened before this work began.
The result of one work cycle becomes context for another. Any conversation can retrieve the updated record when needed, including an older chat working on a different task.

I use Boon to work with my family's documents and ongoing matters. Original files, matter notes, and saved work remain in the archive, independent of any chat. Conversations retrieve relevant sources, and I save replies and useful context back to the shared record.

I'm developing an app around these workflows. The broader direction is a family archive that can outlive its apps, preserving personal accounts and history for future readers.

Courier notification designer with message editing and layout controls

Courier

I built the initial architecture and most of the early implementation of Courier's embeddable message designer. As the team grew, I continued developing its document conversions, editing behavior, and saving workflows.

Propel UI kit with bar, line, and donut chart components

Propel

I was a main contributor to Propel's public UI kit for data interfaces. My work covered chart components, a CSS Modules migration, theme foundations, and the Storybook and packaging setup used to maintain the library.

RapidAPI

I built the original component library while developing the web version of Paw. It became RapidAPI's shared UI Toolkit; by the time I left, 13 projects used it as a dependency. I created its Storybook and integration documentation, and worked with the design team on the shared components and themes.

For teams still using Vue, I proposed a React-in-Vue adapter so they could adopt the toolkit while migrating to React.

About & contact

My background is in complex frontend products. These days, my work extends into AI tools, persistent context, and the reliability of agent-driven workflows. I’m interested in how the interface and the systems behind it work together.

I also build my own products. FamilyBoon grew out of managing my family’s documents and ongoing matters. My goal is to make software that takes more of that work off people’s hands, giving them time and attention back.
