Consulting in Frontend Development for the Expansion of the Ad Manager
The client operates the Ad Manager, a self-service portal for business customers to book and manage advertising products on the GMX and WEB.DE email portals. The Ad Manager is already live and serves as the central platform for campaign management in the B2B sector. A separate B2B portal, the trusted Dialog Manager, currently exists and its features are to be migrated into the Ad Manager.
Project Objective The goal is the technical and functional enhancement of the Ad Manager with features from the trusted Dialog Manager. The first step is the implementation of a unified login system. Building on that, the existing trusted Dialog features will be gradually migrated and made available centrally in the Ad Manager. Since the trusted Dialog Manager was not a self-service tool, this integration will significantly improve usability and accessibility. The focus of the tender is particularly on frontend development (Angular, CSS, HTML).
Scope of Services
- Unified Login System: Integration of trusted Dialog features into the Ad Manager via a central authentication mechanism.
- Domain Overview Page: Development of an overview page with DKIM details, logo/avatar preview, and status information (active, inactive, ready for completion).
- Auth Code Creation: Development of a function to generate time-limited authentication codes to mark test emails.
- Overlay Testmail Intro: Development of an overlay as a step-by-step guide for sending test emails.
- Software Design: Incorporation of current Angular best practices to optimize the codebase in terms of structure, reusability, and maintainability.
