NODE.JS BACKEND DEVELOPER · FREELANCE

Reliable backends. Built with security in mind.

I’m Ellias, a Node.js developer focused on APIs, data, and the logic that makes a product work. I pay close attention to security: authentication, input validation, and common web vulnerabilities, and I’m actively growing in this area. I can also build clean, simple frontends when a project needs one. Outside of code, I’m a professional violinist and an enthusiastic chess player.

02GET IN TOUCH

Good systems start with a conversation.

Have an API to build, a backend to clean up, or an app that needs a security review? Send me a short note with what you’re building, your timeline, and your stack, and I’ll reply with my thoughts.
