What I'm looking for

I seek a role that fosters innovation, collaboration, and opportunities for growth.

I'm a Node.js Backend Developer with over 4 years of experience in crafting scalable, high-performance APIs and server-side applications. My journey has been marked by a commitment to optimizing system efficiency, where I successfully improved performance by 35% through optimized database queries and caching techniques. I thrive in collaborative environments and have a strong background in microservices and cloud deployment, particularly with AWS.

In my recent role at Voyatek Group, I developed RESTful APIs for a travel platform that handles over 10,000 monthly transactions with a remarkable 99.9% uptime. My technical expertise extends to various technologies, including NestJS, Sequelize, and RabbitMQ, which I utilized to enhance system scalability and reduce server costs. I am eager to leverage my skills to deliver robust backend solutions for international tech companies.
