Solving Problems, Overcoming Obstacles

TÜBİTAK Fen Lisesi student (2021-2026) with a passion for competitive programming, cryptography, and AI. Medalist in National and International Informatics Olympiads, Codeforces Master, Competitive Programming Instructor.

About Me

I'm a high school student at TÜBİTAK Fen Lisesi (2021-2026), driven by a passion for solving complex problems through code and innovation. Scoring full marks in the 2021 LGS exam, I ranked in the top 100 among over 1 million candidates.

As an IOI participant, BOI Silver medalist and Codeforces Master (top 1.5% globally), I excel in designing efficient algorithms. My 2.5-year internships at TÜBİTAK BİLGEM B3 Labs and UEKAE Cryptology Unit deepened my interest in cryptographic algorithms and secure systems.

I'm an active member of the JetBrains Youth AI Club, exploring deep learning and GPT models. I've taught machine learning to 20-30 peers across 10+ sessions, sharing my knowledge through hands-on workshops. I actively train students to excel in national olympiads.
