Legacy platform rebuilt for scale and speed

Back to case studies

The challenge

A growing B2B SaaS company was running on a decade-old .NET monolith. Deployments took hours, outages were frequent, and new features required touching fragile shared code. They needed a modern platform without disrupting active customers.

Our solution

TechStart led a phased migration to a microservices architecture on AWS. We introduced domain-driven service boundaries, a React front-end with a unified API gateway, and automated CI/CD pipelines. Each sprint delivered a slice of functionality migrated off the monolith — zero big-bang cutover.

What we delivered

The outcome

The client now ships features weekly instead of quarterly. Engineering morale improved, customer-facing downtime dropped dramatically, and the platform is positioned for the next phase of growth — including mobile and international expansion.
