FAQs
Common questions about database & api development for businesses in Portsmouth.
Yes — every week. CRMs (HubSpot, Salesforce, Pipedrive), payments (Stripe, GoCardless), accounting (Xero, QuickBooks), email and AI APIs. We handle auth, retries, error handling and rate limiting.

Yes — in Node.js (Express, NestJS) or via Next.js API routes. Includes auth, versioning, rate limiting, request validation and OpenAPI docs so other developers can integrate without guessing.
HTTPS everywhere, short-lived auth tokens, parameterised queries (no SQL injection), rate limiting and access logs. For GDPR we minimise data collection, encrypt sensitive fields, and build export/deletion flows.
Yes — every backend is designed with horizontal scaling in mind: stateless API servers behind a load balancer, queue-based background jobs, read replicas for heavy reads, and CDN caching.
