Second Brain
A personal knowledge system I use daily, not a demo I built and abandoned.
Role
Solo build — full stack, personal tool.
Context
Most of what I learn and decide — technical frameworks, execution checklists, business-law questions, sector research — was scattered across notes, tabs, and memory.
I wanted one system I'd actually keep using, which meant it had to be faster than my old habits, not just more organized.
Approach
Built four modules: learning frameworks, execution checklists, a Moroccan business-law reference for company structuring, and sector intelligence covering fintech, greentech, agritech, and retail tech.
Next.js and Supabase for the app and data, OpenAI for retrieval and summarization inside each module, deployed on Vercel.
Outcome
It's the tool I open first when structuring a new company or researching a sector — the test for whether it was worth building.
