FT-OS: "La Otra Liga" Business Operating System

A complete small-business operating system for a food business, in daily production use. One system replaces the usual stack of a website host, a point-of-sale vendor, a kitchen-display subscription, and an inventory tool. It runs on the owner’s own cloud.

Problem

A small food business needs a public website, a way to take orders, a screen in the kitchen, inventory tracking, and an admin to run it all. Buying those as separate SaaS products means per-seat fees, four vendors, and four places where the data lives. FT-OS folds the whole operation into a single system the owner controls.

Build

Owner-editable everything

A non-technical owner can run the business without touching code. That includes a visual website builder with canvas editing, a page manager, nav / header / footer and SEO controls, and a media library. A 53-check operator-simulation end-to-end test exercises the editing flows an owner would actually use.

Operations

POS with a crash-recovery cart, tips, refund/void that restores inventory, and 80mm thermal receipt printing.
A kitchen display system (KDS) for order flow.
Inventory, reports, and one-click backups.

FT-OS inventory: stock levels, low-stock alerts, and cooked-yield production — Inventory: stock, low-stock alerts, and cooked-yield tracking.

FT-OS admin reports: cash reconciliation and order reports by payment method — Admin reports: cash reconciliation and sales by payment method.

Hardening

Built to run unattended in production:

Per-IP lockout and constant-time authentication.
Refuses to boot without a password, so there are no accidental open instances.
Secrets kept out of synced files.
Puerto-Rico-timezone-correct IDs.

QA discipline

A 148-check battery kept green through a full redesign.
A 50-agent QA fleet that surfaced 38 findings.
About 30 saved QA / hardening reports documenting the work.

Multi-tenant SaaS path

FT-OS runs live on AWS Lightsail, Dockerized, with a written path to multi-tenant SaaS: ECS Fargate + EFS, per-tenant subdomains, and S3/CloudFront. I wrote the design doc before the code, on purpose. The single-tenant system in production today is the proving ground for a productized version.
