Silencio Co · E-commerce
My streetwear brand needed a real storefront with customer accounts, plus clear numbers behind the scenes: margins, cash flow, and the break even point, without paying for accounting software.

Overview
A live e-commerce app built with Next.js and TypeScript on a Supabase Postgres database. It runs limited drops with secure customer accounts, and a Google Sheets dashboard behind it works out COGS, margins, receivables, payables, inventory value, and the break even point from raw sales and expense logs.
My role
- Full stack build (Next.js + TypeScript + Supabase)
- Authentication & account management
- Accounting & operations dashboard (Google Sheets)
