I will be your long term backend developer and system architect in nestjs or node


Level 1
About this gig
Are you looking for more than just a coder? I am a Senior Backend Engineer with over 6 years of experience acting as a technical partner, lead architect, and fractional CTO for startups and enterprise clients.
I specialize in building scalable, production-ready backend systems from the ground up, ensuring clean separation of concerns, secure endpoints, and maintainable data flows.
What I bring to your project:
- Deep Expertise: NestJS, Node.js, Express, PostgreSQL, MongoDB.
- Architecture First: Clean structure (API, services, data access), role-based access control (RBAC), and rate-limiting.
- Long-Term Partnership: I don't just write scripts; I build systems designed to scale, complete with clear documentation and structured Git repos.
- Flexible Engagement: Available for code reviews, architecture blueprints, or dedicated weekly retainer development.
Whether you need to rescue an existing codebase or build a new platform the right way from day one, let's talk. Please message me before placing an order to discuss your project scope.

For back end AI Infra work I would only work with Alingga and Nextera again. He understood the challenge quickly, addressed it exactly how I wanted and delivered ahead of schedule. He is a good communicator and extremely competent coder. Thank you for a great collaboration.
