Backend Development, REST APIs & Third-Party IntegrationsOmar Hashmi
I build reliable backend systems and API integrations for web applications, SaaS platforms, and AI-powered products.
If your frontend is ready but the backend is missing, your APIs need improvement, or your application needs to connect with external services, I can help implement the required functionality.
What I can deliver:
REST API development using Node.js or Python
FastAPI and backend service development
Database schema design and query optimization
MongoDB and PostgreSQL integration
Authentication, authorization, and role-based access
Third-party API integrations and webhooks
Payment, email, and notification integrations
Backend debugging and performance improvements
API documentation, testing, and deployment support
I focus on maintainable code, clear API contracts, appropriate security controls, and dependable error handling.
Before starting, I review your requirements, existing architecture, expected integrations, and deployment environment to establish a clear scope.
Whether you need a new backend, a missing API endpoint, or help integrating external services, let's discuss the implementation.
