Duration: 12 months
Team: 8 specialists

50x

User growth supported

The Challenge

TechFlow Solutions was experiencing rapid growth but their technology infrastructure couldn't keep pace, threatening their ability to serve customers and scale the business.

Monolithic Architecture Limitations
Single monolithic application struggling to handle rapid user growth and feature demands

Impact: Frequent downtime, 45-second page load times, development bottlenecks

Manual Deployment Processes
Time-consuming manual deployments taking 4+ hours with high risk of errors

Impact: Weekly deployment cycles, 30% deployment failure rate

Scalability Constraints
Infrastructure couldn't handle traffic spikes during peak usage periods

Impact: Service outages during 50K+ concurrent users, lost revenue opportunities

Limited Observability
Lack of monitoring and analytics made it difficult to identify and resolve issues

Impact: Mean time to resolution of 6+ hours, poor user experience insights

Our Solution

We implemented a modern, cloud-native architecture designed for rapid scaling and operational excellence.
