About this gig

Looking for a reliable backend that won't break under real-world use? I'm a Node.js developer with 4+ years of experience, currently owning the entire backend and database for a live pharma SaaS application built from scratch.

What I bring:

  1. Clean, scalable REST API development (Node.js, Express)
  2. PostgreSQL schema design & query optimization
  3. Secure authentication (JWT, OAuth)
  4. Production-grade error handling and testing
  5. Experience fixing real production database issues under pressure

Whether you need a single API endpoint or a complete backend architecture, I focus on writing code that's maintainable, secure, and ready to scale not just "working."

Backend developer with 4+ years of experience in Node.js and PostgreSQL. I currently own the entire backend and database for a live pharma SaaS application — built from scratch, including complex system design and fixing critical production issues. I focus on writing code that holds up under real-world pressure: secure APIs, clean architecture, and databases that don't break under load. I also build AI agents, pairing LLM automation with solid backend infrastructure so they're production-ready, not just prototypes. If you want someone who treats your project like a live system, let's talk.
