Frequently asked questions
Should we build a REST API or GraphQL API?
REST APIs are standard, easy to cache, and ideal for straightforward web/mobile integrations. GraphQL excels when multiple client platforms need flexible, custom data queries in a single round-trip.
How do you guarantee backend API security?
We follow OWASP top 10 security standards, implementing rate-limiting, CORS policies, JWT/OAuth token rotation, strict input validation with Zod, and data encryption at rest and in transit.
Can you optimize or rewrite our slow database queries?
Yes, we perform backend performance audits, analyzing query execution plans, adding missing database indexes, and setting up Redis caching layers to reduce database load.
