  • Working knowledge of MySQL and WordPress database structure
  • Comfort with Git-based workflows and basic command-line tools

Preferred

  • Experience with African payment gateways (Yoco, PesaPal) or similar regional providers
  • Familiarity with 3CX plugin configuration and VoIP/chat website integrations
  • Google Tag Manager, GA4, and Facebook Pixel implementation experience
  • Knowledge of web performance optimization: caching layers, image compression, CDN configuration
