Varinder
About this gig
Hi, I'm Varinder, a full stack developer with 5+ years of experience specializing in backend development using Node.js, Express, and both MongoDB and MySQL.
I currently work as an SDE-2 Full Stack Engineer building an AI agent and workflow-automation platform, where I built the integration layer connecting 100+ third-party SaaS platforms via REST APIs, OAuth 2.0, and webhooks, and implemented multi-tenant role-based access control (RBAC).
What I offer:
Backend API development with Node.js and Express. Database design and optimization with MongoDB or MySQL. Authentication and authorization (JWT, OAuth 2.0). Third-party API integrations and webhook handling. Multi-tenant architecture and RBAC. Clean, documented, production-ready code.
I've built backend systems handling multi-tenant SaaS platforms with complex integrations and secure access control. I focus on scalable architecture, clean code, and reliable delivery.
Message me before ordering so we can discuss your backend requirements.
