High-Performance API Engineering

Enterprise API Development
Services Built for Scale.

Your apps are only as good as the data they can access. We build secure, lightning-fast REST and GraphQL APIs that power your web and mobile applications.

Why Your Business Needs a Custom API

Whether you're building a mobile app, integrating third-party services, or opening your platform to partners, a well-designed API is the backbone of modern software. Off-the-shelf integrations often fall short when it comes to security, speed, and custom business logic.

We design APIs that are not just functional, but developer-friendly. This means clean documentation, predictable responses, and robust error handling β€” making it easy for your team (or your clients) to build on top of your platform.

Our API Engineering Capabilities

  • ✦
    REST & GraphQL Architecture We build scalable REST APIs for standard integrations and GraphQL APIs for complex, data-heavy applications where clients need precise control over the data they fetch.
  • ✦
    Bulletproof Authentication & Security We implement JWT, OAuth2, API keys, and rate-limiting. Your APIs are protected against common OWASP threats like SQL injection and DDoS attacks.
  • ✦
    Third-Party Integrations Stripe, Razorpay, Twilio, Salesforce, HubSpot β€” we connect your system seamlessly with the tools you already use. We also build robust webhook systems.
  • ✦
    Microservices & Serverless Break your monolith into manageable microservices. We deploy serverless functions (AWS Lambda, Vercel) for high availability and low latency.
  • ✦
    Interactive API Documentation We provide Swagger/OpenAPI documentation so your developers (or third-party partners) can test endpoints directly in the browser.
  • Technologies We Master

    We choose the right stack based on your specific use case, team size, and scale requirements. No dogmatic tech choices.

    Our Development Process

    01

    API Discovery & Design

    We map out data models, endpoints, and authentication flows before writing code.

    02

    Development & Testing

    We build the API with automated unit and integration tests to ensure reliability.

    03

    Documentation & Sandbox

    We generate Swagger docs and set up a sandbox environment for safe testing.

    04

    Deployment & Monitoring

    We deploy to production with rate-limiting, logging, and uptime monitoring.

    Service FAQ

    Common Questions.

    How much does it cost to build a custom API?

    A standard REST API typically starts around $1,500–$3,000 depending on the number of endpoints and integrations. We provide a fixed-price quote after a discovery call.

    Do you provide documentation?

    Yes, every API we build comes with complete Swagger/OpenAPI documentation and a Postman collection for easy testing.

    Can you integrate with our existing legacy system?

    Absolutely. We frequently build middleware and API wrappers around legacy databases or older SOAP APIs to modernize them.

    How do you handle API security?

    We implement rate-limiting, JWT/OAuth2 authentication, input validation, and encryption. We also conduct penetration testing before launch.
