About

A quick introduction to who I am and how I work.

I am an Informatics student at Del Institute of Technology with a strong interest in building practical web and mobile applications. I like working on products that make workflows clearer, easier to maintain, and useful in real situations.

My work so far includes software development, system analysis, teaching support, and organization responsibility. That mix helps me think about both technical details and how people actually use the systems I build.
