Backend Development FAQs
Questions about how we work, what to expect, or how we structure engagements? The answers most clients ask about, below.
Node.js/NestJS is ideal for real-time, I/O-heavy apps. Python/Django excels for data-driven APIs. Java/Spring is best for large enterprise systems. Go is perfect for high-concurrency microservices. We choose the right tool based on performance requirements, team expertise, and project constraints.
We implement multi-layered security: OAuth 2.0/OIDC for authentication, JWT with short-lived tokens, RBAC/ABAC for authorization, rate limiting, input validation, SQL injection prevention, and automated OWASP vulnerability scanning in CI/CD.
Yes. We use the strangler fig pattern to incrementally decompose monoliths into microservices, starting with the highest-value domain boundaries. This approach minimizes risk and allows gradual migration without service disruption.
Through circuit breakers, retry policies, health checks, blue-green deployments, chaos engineering, comprehensive monitoring (Prometheus/Grafana), and automated alerting. We target 99.99% uptime SLA.
