FAQ
Backend & Architecture — common questions
When should we invest in scalable architecture?
Early enough to avoid painful rewrites, but scoped to your stage— we right-size design for current traffic with clear extension points.
Spring Boot or Django—which do you recommend?
It depends on your team and ecosystem. We often use Spring Boot for enterprise Java environments and Django for rapid Python delivery.
Can you work alongside our frontend team?
Yes. We define API contracts collaboratively and ship backend increments aligned to frontend milestones.
Do you handle cloud deployment?
We configure containers, environments, and CI/CD hooks; deeper DevOps can be scoped as needed.
How do you approach security?
Least-privilege access, encrypted transport, input validation, secrets management, and regular dependency updates.
