Backend
Secure APIs & backend systems
Provider keys on the server, not in your browser's network tab.
The most common backend security mistake is a secret that belongs on the server sitting in a frontend bundle or client request. We build the server layer between your frontend and your providers so credentials stay where they belong.
Situations
APIs that hold up under real use
- A public API (contact form, lead capture, app backend) that resists abuse, injection, and runaway traffic.
- Email, webhooks, or third-party APIs with signing keys and credentials on the server — and errors you can debug in production.
- Node.js and TypeScript services with predictable validation, structured logging, and a deployment path your ops team can own.
Typical deliverables: REST-style HTTP APIs with typed validation; outbound email, webhooks, and vendor integrations with retries and documented config; environment-based config, health endpoints, structured logging, and runbooks. See our secure contact API case study for a concrete Fastify and TypeScript walkthrough, or the webhook signatures, idempotency, and retries guide when Stripe or email events need production-safe handlers.
Describe your integration
Tell us what your API needs to do, who calls it (web, iOS, Android), and which providers you need to connect. We will outline a sensible stack and scope.
