Who I Am
A passionate AI engineer with expertise in building enterprise-grade solutions, winning hackathons, and mentoring developers. I transform complex ideas into elegant digital solutions.
Background
A person. A developer. A challenger. Or you can better say — Tayyab.
I have a thrive for everything. I want to see what I can achieve in life — not by sitting idle, but by working as hard as I can. Even when things aren't in my favor, I push forward with determination and purpose.
My journey includes working as an AI Engineer at SAJCO in Riyadh, winning Harvard's CS50x Puzzle Day 2025, ranking 36th globally in Advent of Code 2024 out of 252,800+ participants, and mentoring 200+ students worldwide.
I believe in growth through action — learning by doing, failing fast, and rising stronger. Every line of code I write is a step toward something greater.
