Adding OAuth2 to Existing MVC Core 6 App

The Challenge & Problem Statement

The Core Bottleneck

The existing MVC site now has two ways to authenticate, one of which needs to change to OAuth-based (cognito) But another way with link parameters needs to stay still.

Prior to partnering with AsianSol, the client faced multiple technical and operational constraints that restricted business growth:

Legacy architecture suffered from scalability bottlenecks and lacked automated integration hooks.
Client stakeholders needed rapid 2-week sprint milestones with demonstrable staging demos.
Security and data privacy required hardened zero-trust authorization and audit logging.
Manual overhead was creating roadblock delays across customer-facing operations.

The Solution & Engineering Strategy

AsianSol engineered a custom, production-grade platform utilizing senior in-house developers, test-driven methodology, and modern cloud deployment standards.

Architected decoupled services with clean, maintainable contracts and automated CI/CD.
Implemented end-to-end automated testing to guarantee zero regressions during updates.
Engineered intuitive, modern UI task panes and dashboards for maximum user efficiency.
Delivered complete documentation, handover walkthroughs, and ongoing SLA maintenance.
