[ABOUT • SKILL TREE]

Who I am

Master's in Software Engineering with a passion for building robust, scalable systems. Currently focused on Spring Boot, API platform development, and exploring AI-enhanced automation using Spring AI and intelligent agents.

Recent highlights include developing an API Platform for ONCF, implementing AI-driven field data analysis systems, and contributing to enterprise-level applications during internships at 3M and ONCF.

Beyond enterprise development, I enjoy prototyping 2D exploration games and experimenting with creative coding to keep the spark of innovation alive.
