Architecting Secure, Performant, and Maintainable Backends
One Team US delivers reliable backend architectures optimized for uptime, data integrity, and seamless API integration. We combine modern frameworks with DevOps discipline to deliver resilient systems that scale with your business needs.
Backend Engineering Capabilities
Scalable RESTful and GraphQL API Design
Build flexible, performant APIs with proper versioning, documentation (OpenAPI/Swagger), and rate limiting for enterprise-grade systems.
Microservices & Container Orchestration
Design distributed systems using Docker containers and Kubernetes for scalability, fault tolerance, and efficient resource management.
Database Optimization and Indexing
Optimize PostgreSQL, MSSQL, and MongoDB for query performance with proper indexing, connection pooling, and caching strategies.
Cloud Deployment
Deploy to Azure, AWS, and GCP with Infrastructure as Code (Terraform), auto-scaling, and high-availability configurations.
Authentication & Authorization
Implement secure authentication with OAuth 2.0, SSO (SAML/OpenID), JWT tokens, and role-based access control (RBAC).
CI/CD Automation
Set up automated pipelines with GitHub Actions, Jenkins, and GitLab CI for testing, building, and deployment workflows.
Legacy System Modernization
Migrate legacy Java or .NET Framework systems to modern .NET Core, Python FastAPI, or Node.js architectures incrementally.
Logging, Monitoring & Performance Tuning
Implement comprehensive logging (ELK stack), APM (Application Insights, New Relic), and performance profiling for production systems.

Backend Development Process
1. Requirement Analysis & Architecture Planning
Gather technical and business requirements, design system architecture, choose appropriate tech stack and database models.
2. API Design & Documentation
Define API contracts with OpenAPI/Swagger, establish versioning strategy, and document authentication flows.
3. Core Module Development
Build business logic, implement data access layers, integrate third-party services, and establish error handling patterns.
4. Integration & Testing
Write unit and integration tests, perform load testing, security audits, and API contract validation.
5. Performance Optimization
Profile and optimize database queries, implement caching strategies, optimize memory usage, and reduce API response times.
6. Deployment & Monitoring
Deploy to production with blue-green strategy, set up logging and monitoring, configure alerts, and establish incident response.
