About Me

Get closer...

I am a Full Stack Engineer with over 3 years of experience in building scalable and high-performance web applications. While I am proficient in the entire development lifecycle, my core strength lies in Backend Engineering using Go (Golang) and Node.js, as well as managing infrastructure with Docker.

On the frontend, I craft responsive and interactive interfaces using React and TypeScript. I have a proven track record of delivering complex enterprise solutions—from IoT monitoring dashboards to secure financial transaction systems. I am dedicated to writing clean, maintainable code and optimizing system architecture for stability and speed.
