About Me

Who am I?

I started my programming journey during my diploma in Computer Technology, where I was first introduced to web development and problem-solving through code. What began as curiosity quickly turned into passion as I started building real-world applications and exploring how software can solve everyday challenges. Over time, I transitioned into full-stack development, working with different technologies and gaining hands-on experience in building scalable systems, automation tools, and data-driven platforms.

I enjoy working on projects that involve system design, backend architecture, and performance optimization, especially where I can build something impactful from scratch. Recently, I’ve been focusing more on AI integration, automation, and data processing systems, which I find both challenging and exciting.

Location: Dhaka, Bangladesh

Experience: 3+ years in Full Stack Development

Focus: Full Stack, AI Integration, Cloud Solutions

Beyond Code

Beyond coding, I like to keep my life balanced. I enjoy learning new technologies, exploring productivity systems, and thinking about innovative ideas. In my free time, I also like watching tech content, improving my workflow, and occasionally playing games or spending time with friends.

I love exploring emerging technologies and sharing knowledge with the development community. Always open to discussing interesting projects and opportunities!
