Valle Fuego · Management App

The problem

The business had been running on an Excel workbook that had reached its limit: sales, purchases and expenses, stock, and sales-team commissions each lived in separate tabs, getting harder to keep consistent with each other over time.

The approach

I designed and built a custom internal management app that migrates all of that into one system: sales records, purchase/expense/payment tracking, stock control (correctly kept separate from historical sales, which shouldn’t affect it), and sales-team commission calculations.

The first version was built with React and Vite, meant to run locally during the validation phase with the real business. The planned path to a multi-user version replaces local storage with a real database (Supabase) deployed on Vercel, so the whole team can use it at once from anywhere.

The outcome

A system that gives the business a single source of truth for sales, stock, and commissions, replacing a spreadsheet that had stopped scaling — with a clear path to a production multi-user version.
