Builds Archive
Short-cycle builds, pivots, and lessons worth keeping.
Hackathons, builder tracks, and fast prototypes that taught me something useful. This archive covers 8 builds across 7 focus areas, and 2 of them carried on after the event ended.

FocusFlow
Problem
Most focus tools rely on static website blocking and fail to understand what the user is actually trying to accomplish, which leads to either over-blocking or ineffective distraction control.
Build
We built FocusFlow, an AI-assisted focus system that connects a Chrome extension with a Next.js dashboard and Convex backend. During a session, the extension monitors live tab activity, extracts page content, and uses an LLM to classify whether each tab aligns with the user’s goal. Distractions are blocked with contextual overlays, while users can manually override decisions. After each session, the system generates analytics like distraction rate, top blocked domains, and an AI summary of behavior.
Takeaways
- AI becomes significantly more useful when embedded into a real-time feedback loop instead of being used as a standalone feature.
- System design across multiple surfaces like the extension, backend, and dashboard matters more than any single component.
- Balancing automation with user control through overrides leads to a better UX than a fully rigid system.
