A fast-growing SaaS startup needed to overhaul their backend infrastructure to handle rapid user growth and ensure high availability and performance.
The startup partnered with Code Elevator to design a scalable, secure, and maintainable backend architecture that could support future feature expansion and traffic spikes.
- Existing monolithic backend couldn’t scale efficiently
- High server response times causing poor user experience
- Need for fault-tolerance and zero downtime deployments
- Ensuring smooth integration with frontend and third-party services
- Implementing robust security and data protection
Code Elevator deployed a dedicated backend engineering team:
- 4 Backend Developers (specializing in microservices and APIs)
- 1 DevOps Engineer
- 1 QA Engineer
Execution
Phase 1: Architecture Planning (2 Weeks)
Analyzed current system bottlenecks
Designed microservices architecture with clear service boundaries
Planned database schema, caching, and load balancing strategiesPhase 2: Development & Migration (6 Weeks)
Developed individual microservices using Node.js and Docker containers
Implemented RESTful APIs and message queues for inter-service communication
Migrated data and traffic incrementally to new services to avoid downtimePhase 3: Testing & Optimization (2 Weeks)
Performed load and stress testing to ensure scalability
Set up continuous integration and deployment pipelines
Enhanced security with OAuth 2.0 and JWT authentication
Code Elevator’s backend team delivered a robust architecture that grew with us. We now confidently handle thousands of users with no performance issues.
