Current Choice: online marketplace for electricity suppliers

The challenge

The platform had to integrate multiple third-party APIs from suppliers and utilities to retrieve consumption data, available plans and pricing, and to process switches — while managing location-based availability constraints for suppliers and plans across service areas.

Our solution

• Unified multiple third-party service interfaces behind a single generic interface.
• Implemented unique adapters for each third-party service.
• Used dependency injection and design patterns for a flexible, extendable architecture.
• Moved the entire switching process online to reduce manual handling.

Results

• Increased revenue from residential switches to other suppliers and utilities.
• Significantly reduced man-hours needed to handle the switching process.
