Description

Looking for a backend developer capable of designing high-performance APIs, managing real-time systems, or integrating advanced features like a chatbot or a matching system?

I can help you develop robust and scalable solutions in Node.js (TypeScript), tailored to your business needs.

Specifically, I focus on:

- Creating and optimizing backend APIs (REST / GraphQL)

- Implementing real-time systems (messaging, notifications)

- Developing complex business logic (matching, automation)

- Integrating external services (Firebase, SMS API, Meta API)

- Improving performance and scalability

What sets me apart:

I have practical experience on complex projects, including a candidate/job matching system with scoring, real-time notifications, and the integration of an AI chatbot. I prioritize clean, maintainable, and performance-oriented solutions.

I primarily work on:

- Web / SaaS platforms

- Marketplaces

- Applications with real-time features

- Projects involving artificial intelligence

My goal: to deliver a reliable, high-performance backend ready to scale with your product.
