About Me
A look into how I think, what drives my engineering choices, and what I'm building next.
Computer Engineering student and software developer focused on building practical, production-oriented software. I work across full-stack development, backend engineering, Android, databases, system design, DevOps, and self-hosted infrastructure.
I'm a Computer Engineering student at GHRCEM Pune with a strong interest in software development and problem solving. I learn primarily by building projects and working through real engineering problems rather than limiting myself to theoretical knowledge. My experience includes full-stack web development, Java and JavaScript development, REST APIs, databases, Android development, VPS deployment, Docker, and modern development workflows. I've worked on projects ranging from e-commerce and travel applications to financial management and business-management systems. I'm particularly interested in understanding how software works beyond the UI — including backend architecture, databases, APIs, deployment, security, scalability, and system design.
“Build real things, understand how they work, and keep improving them.”
