I design and build scalable REST APIs and integrate third-party services into web applications, helping businesses create reliable, secure, and high-performance backend systems.

What I can build:

• Custom REST APIs with Node.js and Express.js • Third-party API integrations (OpenAI, WhatsApp, Stripe, Razorpay, etc.) • Authentication and authorization (JWT, OAuth, Clerk) • Database design and optimization with PostgreSQL and MongoDB • Webhook setup and event-driven workflows • API documentation, testing, and validation • Backend architecture for SaaS and business applications

What you'll get:

• Secure and scalable API architecture • Clean, maintainable, production-ready code • API documentation and testing support • Deployment and integration assistance • 7 days of post-delivery support

Tech Stack: Node.js, Express.js, TypeScript, PostgreSQL, MongoDB, Prisma, REST APIs, Railway, and Vercel.

Ideal for startups, SaaS products, agencies, and businesses that need custom backend systems or third-party API integrations.
