Overview & Problem Space

Garment manufacturing is notorious for costly production leaks caused by untracked fabric wastage, missing accessories during stitching runs, and delayed order handoffs.

The Friction:

Factories manage tens of thousands of meters of fabric across dozens of colorways using physical paper chits and chaotic WhatsApp messages, leading to massive stock discrepancies and delayed fashion drops.

Target Operator:

Fashion labels, boutique garment manufacturers, and apparel production coordinators.

The Solution & Contribution

A modern, tactile operations portal that brings precision inventory tracking, automated cost calculations, and visual order pipeline kanbans to the factory floor.

Direct Responsibility & Engineering Role:

Lead Architect & Systems Engineer — Designed the relational database schema for fabric yield tracking, built the FastAPI REST microservices, and developed the Next.js production management UI.

Key Features & Capabilities

Fabric Roll Inventory

Inventory

Tracks roll meterage, supplier dye lots, GSM specs, and post-cut remnant yardage in real time.

Production Order Pipeline

Operations

Step-by-step garment stage tracking: Cutting → Embroidery → Stitching → Washing → Final QC.

Accessories & Trims BOM

Costing

Calculates exact button, zipper, thread, and label requirements based on size-ratio production quotas.

Factory Expense Ledger

Finance

Captures daily labor costs, machine maintenance, and operational overheads against specific production batches.

Engineering Decisions & Insights

Enforced a strict daylight light-mode UI for the operations interface, as factory floor tablets operate under harsh industrial fluorescent lighting where dark mode suffers from heavy screen reflection.

Separated API authentication into stateless HMAC tokens with 12-hour expiration for security without session bloat.

Accommodating fabric shrinkage variations required building custom unit-of-measurement converters into the cutting order creation form.
