Node.js Backend Developer – Remote (Full-Time)
About Mohamed Amine
Senior Node.js Backend Engineer | APIs, SaaS Backends, Nest.JS
Sousse, Tunisia - 3:25 am local time
If your SaaS needs a backend you don’t have to worry about at 2 a.m., I can help.
I’m a Senior Node.js Backend Engineer focused on production-ready systems for SaaS products. I work with founders and technical teams who need clean architecture, predictable performance, and code that can be maintained long after the first release.
Backend capabilities
- Node.js and TypeScript for robust, type-safe services
- NestJS and Express for well-structured, testable APIs
- REST and GraphQL API design and implementation
- MongoDB and PostgreSQL data modeling and performance tuning
- Redis for caching, queues, and rate limiting
- Backend architecture for multi-tenant SaaS products
- Refactoring and stabilizing existing backends
Who I work best with
- SaaS founders preparing for growth or fundraising
- Startup teams building or rebuilding core backend systems
- CTOs who want a dependable engineer they don’t need to micromanage
How I work
- Start by understanding your product, constraints, and risk areas
- Propose clear technical solutions with tradeoffs explained
- Write readable, well-structured code aligned with your long-term goals
- Communicate progress clearly and surface issues early
- Deliver in small, verifiable milestones rather than big surprises
If you’re looking for a backend engineer who prioritizes reliability, clarity, and long-term maintainability, let’s discuss your system and see if I’m a good fit.
