Legacy system holding back growth
Our client's 15-year-old monolithic application was struggling under the weight of modern demands. Slow transaction processing, frequent system crashes, and inability to meet new regulatory requirements were costing them customers and revenue.
- Performance issues: 8-12 second average transaction time
- Downtime: 2-3 hours of unplanned outages monthly
- Compliance gaps: Unable to implement required security protocols
- User frustration: 2.1/5 average app store rating
- Technical debt: Codebase impossible to maintain or scale
Cloud-native microservices architecture
Architecture Redesign
Broke down the monolith into 24 independent microservices. Each service handles a specific business function and can be deployed, scaled, and updated independently.
Cloud Migration
Migrated to AWS with auto-scaling, load balancing, and multi-region deployment. Infrastructure-as-code with Terraform for consistent, repeatable deployments.
Zero Downtime
Implemented blue-green deployment strategy. Migrated users gradually over 6 weeks with real-time data synchronization between old and new systems.
Modern Frontend
Rebuilt web interface with React and mobile apps with React Native. Unified design system ensures consistency across all platforms.
Real-time Analytics
Custom analytics dashboard with real-time transaction monitoring, fraud detection alerts, and business intelligence reporting.
Enhanced Security
Implemented OAuth 2.0, two-factor authentication, end-to-end encryption, and comprehensive audit logging to meet regulatory requirements.

React, React Native, TypeScript
Node.js, Python, Java Spring
