How do you ensure backend security?

Security is built into every layer. We implement secure authentication (OAuth 2.0, JWT), role-based access control, input validation, SQL injection prevention, encryption for data at rest and in transit, comprehensive audit logging, and rate limiting. We conduct security audits and can achieve compliance certifications like SOC 2, HIPAA, and PCI DSS.

Can you work with our existing database?

Yes, we regularly work with existing databases. We can optimize queries, add proper indexing, refactor schemas for better performance, and migrate data if needed. We have experience with legacy databases from Oracle to MySQL and can integrate new backend code with existing data structures while improving performance and maintainability.

How do you handle high-traffic scaling?

We design for scale from day one. This includes horizontal scaling with load balancing, database read replicas and sharding, caching strategies with Redis, message queues for async processing, and auto-scaling cloud infrastructure. We have built backends handling 10M+ requests daily. Our architecture decisions are always informed by your growth projections.

Do you provide API documentation?

Comprehensive documentation is standard with every project. We create OpenAPI/Swagger specifications for REST APIs, GraphQL schema documentation, interactive API explorers, code examples in multiple languages, integration tutorials, and Postman collections. Documentation auto-generates from code to stay in sync.

What about ongoing maintenance and support?

We offer various support arrangements from ad-hoc assistance to dedicated support contracts. This includes monitoring and alerting, performance optimization, security updates, feature enhancements, and 24/7 emergency support for critical systems. Many clients keep us on retainer for continuous improvement and rapid response.
