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.
- 70%Faster deployments
- 99.9%Platform uptime
- 3×Release frequency
What we delivered
- Microservices architecture with clear domain boundaries
- React SPA with role-based dashboards
- AWS ECS, RDS, and CloudFront setup
- GitHub Actions CI/CD with automated testing
- Observability stack with logging and alerting
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.
