About Me

“Building intelligent systems that help people learn, grow, and achieve their goals through AI.”

I am an Informatics student passionate about building digital solutions that address real-world problems in education and productivity.

I am deeply interested in how Artificial Intelligence can evolve from simple chat interfaces into autonomous, agentic systems capable of helping users plan, manage, and achieve their goals.

I believe that the best technology is not just the most advanced, but the one that delivers genuine, practical impact for its users.

Through academic projects and personal research, I have developed competencies in:

Frontend Development
Backend Development
Database Design
Workflow Automation
Artificial Intelligence Integration
Retrieval-Augmented Generation (RAG)
Agentic AI Systems

Selected Work

Projects that solve real problems.

01

Personal Learning Manager (PLM)

AI / EdTech· 2026
Personal Learning Manager (PLM)

An intelligent, self-regulated learning system integrating Agentic AI and Retrieval-Augmented Generation (RAG). It enables students to upload raw course materials, automatically generate tailored study plans, generate active recall quizzes, and dynamically schedule study sessions around real-life constraints.
