Projects
Private knowledge platform that turns curated content into a queryable second brain. Captured links and notes are embedded with Voyage AI and stored in Postgres + pgvector; natural-language questions trigger semantic retrieval and are answered by Claude through a custom RAG pipeline. Built as a single Nuxt 3 + TypeScript app on Supabase (auth + Postgres + pgvector), deployed on Vercel.
Private, no-login IELTS Speaking trainer with AI feedback. Practice spoken answers and get instant, structured coaching on fluency, vocabulary, grammar, and pronunciation. Built with Nuxt 4 and Gemini — audio is analyzed in real time and never stored, with only a streak counter kept in the browser.
WhatsApp-first financial companion that turns receipts and freeform Spanish text into structured expense data through a natural-language extraction pipeline (Gemini AI) over a Nuxt + Express stack. Dual modes for collaborative trip splitting and personal tracking.
Construction expense management platform. Site teams log expenses through a natural-language pipeline (Gemini AI) on WhatsApp, and a web dashboard surfaces real-time insights and financial reports for builders and clients.

E-commerce platform for sports jerseys and apparel. Features product catalog, shopping cart, advanced search & filtering, and admin management tools.
