Backend Development & APIs
Robust, scalable server infrastructure — the backbone of your digital product
The Foundation That Never Fails
Every millisecond of API latency, every database bottleneck, every unhandled exception translates directly into lost revenue and eroded user trust. Xenotrix engineers backend systems designed from the ground up for performance, security, and infinite scalability — the invisible infrastructure that makes your product truly enterprise-grade.
Backend Capabilities
RESTful & GraphQL API Development
Well-documented, versioned APIs built with FastAPI or Django REST Framework — following OpenAPI 3.0 specifications, enabling seamless integration with web frontends, mobile apps, and third-party services.
Microservices Architecture
Decompose complex monoliths into independent, domain-specific microservices — enabling independent scaling, isolated deployments, technology flexibility, and resilient fault isolation for enterprise-grade systems.
Database Design & Optimization
Expert PostgreSQL schema design, query optimization, indexing strategies, connection pooling, and read replica configurations — ensuring your database handles millions of operations per day without performance degradation.
Authentication & Security Architecture
JWT, OAuth 2.0, API key management, role-based access control (RBAC), rate limiting, input validation, SQL injection prevention, and OWASP Top 10 compliance — security engineered at every layer.
Cloud-Native & Containerized Deployments
Docker containerization, Kubernetes orchestration, CI/CD pipeline setup with GitHub Actions, auto-scaling groups, load balancers, and cloud-native deployments on AWS, GCP, or Azure.
Performance Engineering & Caching
Redis caching layers, CDN integration, database query optimization, asynchronous task queues with Celery, and background job processing — engineering systems that remain fast at any traffic volume.
