ShopOps: All-in-One Operations Intelligence & E-Commerce SaaS

"Think of ShopOps as a flight control tower for online Etsy sellers. It calculates hidden marketplace fees so you never lose money, spots trending products, and keeps your private store data locked tight."

1. The Problem (Why I Built This)

Selling products internationally on Etsy seems simple, but hidden operational traps wipe out profits:

• 6 Layers of Hidden Fees: Listing fees, transaction fees, processing fees, state taxes, and mandatory 15% offsite ads mean sellers often sell hundreds of items but end up losing money.
• Accidental Trademark Bans: Putting a registered word (like "Velcro" or "Barbie") in a title can instantly get a shop banned permanently.
• Expensive Foreign Tools: Platforms like eRank charge $30–$99/month, yet lack automated order export formatting for popular print-on-demand fulfillment hubs.

2. How I Solved It (Under The Hood)

ShopOps combines accurate financial mathematics, fast API scraping, and browser-side cryptography:

• Client-Side Zero-Knowledge Encryption: Sensitive tokens are encrypted inside the seller's browser using Web Crypto API (AES-256-GCM + PBKDF2). Even if the backend database were leaked, seller secrets remain mathematically unreadable.
• Multi-Key Rotation & Rate Smoothing: Distributes background requests across multiple Etsy API keys to eliminate rate limits.
• Distributed Background Worker: Heavy background jobs (competitor tracking, image rendering) run on a lightweight worker service, reducing Redis command volume by 85% via smart polling pacing.
• Trademark Shield: Scans listing titles and tags against registered USPTO trademarks using word-boundary regex to prevent account suspension.
• 1-Click Multi-Hub Fulfillment: Formats orders instantly for Gearment, Printify, and BurgerPrints, saving sellers 2–3 hours of manual copy-pasting every day.
