About Me
I am a Full Stack Developer with 5 years of specialized experience in backend development using Node.js and TypeScript, and 2 years of hands-on experience building modern, responsive frontend applications using React.js.
I started my career as a PHP developer, where I built and maintained web applications across different domains, gaining strong fundamentals in web development, backend logic, and database design. Over time, I transitioned into JavaScript and TypeScript, with a primary focus on designing scalable backend systems, REST APIs, and microservices using Node.js, while also contributing to frontend development using React.js.
My core expertise lies in backend engineering, system design, and building scalable cloud-ready applications. I have experience across the full application lifecycle, including API development, database design, cloud deployment, CI/CD pipelines, and performance optimization. I also work with frontend technologies to deliver complete end-to-end solutions.
I enjoy solving complex engineering problems, improving system architecture, and building reliable full-stack applications that deliver real business value.
