Full-stack platform

Where Are They? (dondeestan.cl): Full-stack platform built on Supabase PostgreSQL from the ground up. Designed and implemented the complete database architecture: 63 migrations, Row Level Security (RLS) policies, full-text search with Spanish stemming, and incremental data sync using SHA-256 change detection. The project aggregates 3,216+ records from 4 external sources through a Python ETL pipeline with 99% deduplication accuracy, AI-powered image restoration (Real-ESRGAN + GFPGAN), and a Nuxt 3 frontend. Hosted on GitHub with a monorepo structure, CI/CD via GitHub Actions, and Vercel deployment. This project demonstrates deep Supabase expertise: auth, storage, database design, RLS, edge functions, and seamless integration with a modern frontend stack.
