Backend engineer looking to join early-stage startups

I'm a backend engineer who builds scalable SaaS platforms and backend systems. My stack: NestJS, TypeScript, PostgreSQL, Docker, Redis.
If you're building something and need an engineer who can architect the backend from scratch, handle multi-tenant setups, or integrate AI/ML into your product — let's talk.
Recent work includes:

• Multi-agent AI appointment booking platform (LangGraph + NestJS)
• B2B procurement SaaS with WhatsApp integration
• Self-hosted analytics platform

Not looking for equity-only. Open to equity + competitive pay or straight contract work depending on the stage.
