Solar Reviews — Solar Estimation Platform

Situation

The platform was based on an existing legacy web application that needed modernization while remaining operational in production. Key challenges included:

Modernizing legacy backend services without a full system rewrite.
Improving API response performance.
Continuing new feature development while modifying existing production components.
Integrating with CRM systems and third-party solar services.
Maintaining compatibility between existing backend services and Vue.js frontend components.
Handling API edge cases and ensuring frontend requirements were correctly supported.
Deploying enhancements safely to an active international production environment.

Task

Enhance and modernize a production solar estimation and calculation platform serving homeowners and businesses seeking solar energy solutions in the United States and Australia. The primary focus was improving backend services, API performance, CRM integrations, and legacy system capabilities while continuing to deliver new product features.

Solution

Enhanced the existing monolithic Laravel/PHP application rather than rebuilding the entire system. The solution focused on incremental modernization through:

Backend API enhancement.
Legacy component refactoring.
RESTful API development.
Solar service API integrations.
CRM integrations.
Performance improvements.
Vue.js frontend/API coordination.
Production-safe deployment practices.
Continued feature development on top of the existing architecture.
