About Salih

đŸ‘šâ€đŸ’» Backend Developer specialized in Node.js / NestJS
With 5 to 7 years of experience, I design and develop robust, scalable, and maintainable backend architectures, primarily with Node.js and NestJS.

💡 What I bring:
‱ Optimized solutions that save the company time and money
‱ Active technological watch: I constantly learn and experiment with new things
‱ Rigor in code quality (tests, architecture, security, performance)
‱ A pragmatic approach: I analyze business needs to propose relevant solutions

🔧 My key technical skills:
Node.js, NestJS, TypeScript, API design (REST / GraphQL), SQL & NoSQL databases, microservices / modular architecture, performance optimization, continuous integration / deployment, advanced debugging.

✹ My collaboration style:
I work autonomously while knowing how to integrate into a team. I like to share my ideas, report blockers, and propose technical improvements. I am results-oriented: I deliver on time and with quality.

📈 Goal for your project:
‱ Save you time & increase efficiency
‱ Ensure a solid technical foundation to evolve your product long-term
‱ Be a reliable partner for your backend challenges
