What I do

Full-service API development covering REST and GraphQL APIs, third-party integrations, webhook implementations, and API security. Building robust, documented APIs that enable seamless system connections.

REST API Development

Building RESTful APIs for your applications. Clean, documented APIs following industry standards.

GraphQL APIs

Flexible GraphQL APIs for complex data requirements. Efficient queries with exactly the data you need.

Third-Party Integrations

Connecting your systems with external services. CRM, payment gateways, shipping, and business tools.

Webhook Implementation

Real-time event notifications between systems. Incoming and outgoing webhooks for automated workflows.

API Security

Secure API design with authentication, rate limiting, and data protection. OAuth, JWT, and API key management.

API Documentation

Comprehensive API documentation using OpenAPI/Swagger. Clear guides for developers to integrate quickly.

Business Impact

Problems I solve

Helping businesses connect disparate systems and enable automated data flow. Reliable integrations that eliminate manual work and enable new business capabilities.

The Problem

Disparate systems that do not communicate, requiring manual data entry

The Solution

Building API integrations that connect your systems. Automated data flow eliminates manual work and reduces errors.

Connected systems with seamless data synchronization

The Problem

Need to expose your application data to partners or customers

The Solution

Developing secure, documented APIs for external consumption. Controlled access with authentication and rate limiting.

API-enabled business relationships and new revenue streams

The Problem

Existing integrations are unreliable or poorly implemented

The Solution

Rebuilding integrations with proper error handling, logging, and monitoring. Robust connections that work reliably.

Stable integrations with proper monitoring and alerts

The Problem

Need real-time data updates between systems

The Solution

Implementing webhooks and real-time APIs for instant notifications. Event-driven architecture for up-to-date data. This approach is commonly used in [business automation](/business-automation) workflows.

FAQ

Frequently asked questions

Common questions about API development and integration. If you have a specific question not covered here, feel free to get in touch.

I develop REST APIs, GraphQL APIs, and real-time WebSocket APIs. The choice depends on your requirements - REST for standard CRUD operations, GraphQL for flexible queries, and WebSockets for real-time features.

In most cases, yes. If your software has an API, I can integrate with it. I work with popular platforms like Salesforce, HubSpot, Stripe, and many others. Custom integrations are also possible.

Security is built in from the start - authentication (OAuth, JWT, API keys), rate limiting, input validation, and data encryption. APIs follow security best practices and are tested for vulnerabilities.

Yes. All API projects include comprehensive documentation using OpenAPI/Swagger or similar standards. This makes it easy for developers to understand and integrate with your API.

Yes. I can debug and fix existing API integrations, improve performance, add features, or rebuild problematic integrations from scratch.

I provide support packages covering API monitoring, updates, and improvements. This ensures your APIs continue working reliably as requirements evolve.
