01The problem

Small teams wanted insights from their spreadsheets and documents without learning a BI tool.

02My contribution

Built it alone on Next.js and Supabase, with email and Google sign-in and row-level security on every table. It parses CSV, Excel, PDF, Word and JSON, infers column types, then produces charts, correlations and outlier detection, with GPT-4o-mini writing the trend summary. Stripe checkout, customer portal and webhooks drive Free, Pro and Team plans with per-plan limits.

03Outcome

A complete SaaS codebase, from upload to billing, in one week. The source is public on GitHub.
