Robust backend systems and APIs that power your products. We design for performance, security, and future growth.
Technologies and Tools
Our Process
We start by writing the API specifications (Swagger/OpenAPI) and defining the exact data contracts before writing code.
We design normalized relational schemas or optimized NoSQL document structures to ensure fast query times.
We build the REST or GraphQL endpoints, implementing business logic, authentication, and third-party integrations.
We simulate heavy traffic spikes and perform penetration testing to ensure the API won’t buckle under pressure.
Use Cases
Centralized servers that power mobile applications, handling user authentication, push tokens, and data syncing.
Public-facing developer APIs that allow third-party companies to securely integrate with your platform.
Modern RESTful layers built on top of old SOAP or mainframe systems to modernize data access.
Decoupled, independently scalable backend services for massive enterprise applications.
Deliverables
Every API & Backend Development project comes with clear, tangible deliverables. No vague promises — just concrete output you can use, deploy, and build upon.
Why Zanvis
An API is only as good as its docs. We deliver beautiful, interactive documentation that developers love.
Strict JWT validation, CORS policies, SQL injection prevention, and sophisticated rate limiting.
We use Redis caching, database indexing, and optimized queries to keep response times blazing fast.
We know when to use standard REST endpoints and when a flexible GraphQL layer is the better architectural choice.
Our APIs are designed to be updated in production without dropping a single active connection.
Stateless backend architectures designed to scale horizontally across hundreds of servers if needed.
