I will build secure nodejs rest apis and third party integrations

Need a secure and maintainable Node.js API or third-party integration? I will design and build REST APIs using TypeScript, Node.js, Express, NestJS, Fastify, PostgreSQL, MongoDB, Supabase, and proven production practices.

I can help with:

REST API endpoints and complete backend modules

Authentication, authorization, validation, and rate limiting

PostgreSQL, MongoDB, and Supabase data models

Payment, messaging, CRM, ERP, webhook, and external API integrations

API documentation, tests, error handling, logs, and monitoring

Deployment support with Docker and cloud environments

You receive clean architecture, readable code, secure configuration, clear documentation, and honest communication about scope and tradeoffs.

Please message me before ordering with your workflow, required endpoints, external service documentation, preferred stack, and expected traffic so I can recommend the right package.
