About Me

A software engineer with 11 years of experience in the tech industry, my career began as an intern full-stack developer, where I honed my skills in both front-end and back-end technologies. Over time, I evolved into a specialized backend developer, driven by a passion for server-side programming and database management.
In the latter part of my career, I have focused extensively on backend development, where I found my true calling. My expertise lies in building robust, scalable, and efficient backend systems, often leveraging cutting-edge technologies and methodologies. I am proficient in a range of backend languages and frameworks, with a particular emphasis on Node.js.
A day in my professional life is characterized by a commitment to quality and efficiency, whether I'm architecting complex backend systems, optimizing database interactions, or integrating APIs. I am always eager to embrace new challenges and continue to grow in the ever-evolving landscape of backend development.
