Project details
Disconnected systems create bottlenecks. Data gets duplicated,
teams work in silos, and simple tasks require too many manual
steps. I build clean, reliable APIs and handle third-party
integrations that connect your systems and keep everything in sync.
Whether you need a REST API built from scratch, an existing API
optimized for performance, or third-party services connected to
your app, I handle the full implementation with clean architecture
and proper documentation.
What I can build for you:
• RESTful API design, development, and documentation
• Third-party integrations (payment gateways, CRM, shipping,
AI services)
• API performance optimization and refactoring
• Authentication systems with JWT and OAuth
• Webhook setup and event-driven integrations
If your systems are not talking to each other or your API is
becoming a bottleneck, let's fix that.
