Problems This Solves

!

Your product needs to integrate with Stripe, HubSpot, or Twilio but your team lacks the backend expertise to build secure, reliable API connections.

!

Your existing API is fragile — breaking frequently, returning inconsistent data, and causing cascading failures in your frontend application.

!

You need a public API for partners or clients but have no documentation, versioning strategy, or rate-limiting infrastructure.

!

Your data lives in multiple disconnected systems (CRM, ERP, warehouse, checkout) with no API layer unifying them.

Methodology

Our Proven Process

1

Requirements & Architecture

We map your data models, endpoint needs, authentication requirements, and third-party integration points to design a scalable API architecture.

2

Schema & Contract Design

We define API contracts using OpenAPI (Swagger) or GraphQL schemas — establishing request/response structures, error codes, and validation rules before writing code.

3

Development & Testing

We build your API using Node.js, Python (FastAPI/Django), or Go with comprehensive unit tests, integration tests, and automated CI/CD pipelines.

4

Security & Rate Limiting

We implement JWT authentication, API key management, CORS policies, rate limiting, and input sanitization to protect against common attack vectors.

5

Documentation & Deployment

We deploy your API to your infrastructure (AWS, GCP, Vercel) and deliver interactive documentation with Swagger UI or GraphQL Playground.

Frequently Asked Questions

REST is simpler, widely supported, and ideal for most CRUD applications. GraphQL is better when your frontend needs flexible queries, you have complex data relationships, or you want to reduce over-fetching. We advise based on your specific use case.
We primarily build APIs in Node.js (Express/Fastify), Python (FastAPI/Django REST Framework), and Go. We choose based on your existing tech stack, team familiarity, and performance requirements.
Yes. We work with PostgreSQL, MySQL, MongoDB, Supabase, Firebase, and DynamoDB. We can build APIs on top of your existing database or design a new schema if needed.
Yes. We offer monthly maintenance plans covering bug fixes, security patches, performance monitoring, and feature additions. Enterprise clients get a dedicated backend engineer.
