Building great things and solving hard problems using just the keyboard is what attracted me to computer science and engineering. It became my passion so I started from just a simple program in Python to building a Reinforcement Learning agent using DQNs. During this period I have learned a lot of things about different topics in computer science. I learned a lot about algorithms and data structure, databases, game development, web development, compilers, machine learning, and many other things. I have created games, built simulators, implemented agents, and built ML models. So every day my passion for this field increases, as there are always new things to learn and great things to implement.
