Frequently asked questions

Our process is efficient. We start with a technical call to define your backend stack, architectural needs, and required experience. We then provide 2-3 matched, vetted candidates for you to interview, enabling a fast hiring decision.

Scalability is central to their process. They design using cloud-native patterns like microservices or well-structured monoliths, implement efficient database strategies, and leverage cloud scaling features, ensuring the application can handle future growth.

Our developers follow an API-first design process. They define clear contracts (e.g., using OpenAPI/Swagger), implement robust authentication and authorization, version the APIs correctly, and write comprehensive automated tests to ensure reliability.

Collaboration is key to their process. They work closely with PMs to understand requirements, define clear API contracts for frontend developers, participate in agile ceremonies, and ensure smooth integration between backend and frontend components.

Security is integrated throughout the development lifecycle. Our process includes secure coding practices (OWASP), implementing robust authentication/authorization, data encryption, input validation, and often involves integrating security scanning tools into the CI/CD pipeline.

A general backend developer may lack crucial SaaS context. When you hire a SaaS application developer from us, their process includes expertise in multi-tenancy, subscription logic, API security for third-party integrations, and scalable cloud architectures specific to SaaS needs.
