Resolve

Full Stack Production Microservice

Overview

Resolve is a full-stack customer support operations platform that enables support teams to handle order modifications, cancellations, and refunds through a structured, auditable workflow. Every operation passes through a review gate before being committed to the live system, with rollback logic in case of downstream failures.

The system integrates deeply with the existing order lifecycle and connects to multiple payment providers — Stripe, PayPal, Klarna, and Adyen — exposing a unified interface for customer support teams regardless of which provider processed the original transaction.
