What I am NOT looking for • A web designer • A theme installer • A basic WordPress developer • Someone who only works with off-the-shelf plugins • Someone without real experience integrating external REST APIs • Someone who has never handled large product catalogs (5,000+ SKUs) If you do not have real experience with API integrations and inventory synchronization, please do not apply. Project Overview I am building a B2B ecommerce. The website (WooCommerce) currently exists as a basic structure. I am looking for a senior developer who can build the technical engine of the project, not just configure plugins. The goal is to integrate supplier APIs (inventory + pricing), implement automated filtering and pricing logic, and build a scalable system. Technical Objective Build a WooCommerce system that: • Integrates via REST API with suppliers • Imports SKU, supplier cost, availability, lead time • Applies automatic rules: • Configurable minimum margin • Availability filter • Lead time filter • Automatically synchronizes prices and stock • Deactivates unavailable products • Generates a clean Google Merchant feed • Handles 1,000–10,000 SKUs without performance issues Required Skills • Advanced WooCommerce development • Custom PHP development • REST API integration • Inventory synchronization systems • WooCommerce performance optimization for large catalogs • Error handling and logging • Database structuring Nice to have: • B2B ecommerce experience • Google Merchant feed implementation • Automated pricing systems Deliberables: 1. Technical architecture proposal before development 2. Working API import and synchronization system 3. Automated filtering and pricing logic 4. Stable, scalable system with documentation Quality and scalability are more important than choosing the cheapest option.
