CS-Care

CS-Care is the customer-service platform of Yalidine, a major parcel-delivery company. It serves 550+ internal staff across 250+ delivery agencies and handles public submissions — complaints and requests — with the main table holding over 1.2 million records. I am the sole developer responsible for implementing new features, maintenance and deployment.

The platform had gathered its share of bugs over time, searches over the 1.2M+ row table of complaints and requests had become slow, and large report exports timed out before completing. Deployment relied on an outdated manual setup.

I fixed the outstanding bugs, optimised the data layer so searches over the full table return near-instantly and large report exports complete reliably, added many new features for staff and agencies, and modernised deployment by moving the platform to Docker.
