Who Am I?
About me.
Hello, my name is Abdul Rehman Khan. I hold a Bachelor's degree in Computer Science, but I have to admit that I did not learn as much as I had hoped in college. However, my passion for technology and self-motivation led me to become a self-taught backend developer based in Hyderabad, India. I am proficient in programming languages such as Python and JavaScript and have experience working with relational databases.
However, what I'm really interested in are microservices, machine learning, and artificial intelligence. These emerging technologies have the potential to revolutionize the way we approach software development and create more intelligent and efficient applications.
My experience in machine learning has given me a deeper understanding of how to create predictive models, and I'm excited to continue exploring this field in the future. As for microservices, I believe that they offer a more scalable and flexible approach to application development, and I'm eager to explore this further.
In addition to my interest in these emerging technologies, my focus is on developing efficient and scalable applications that meet the needs of my clients and end-users. I take great pride in my ability to quickly learn new technologies and adapt to changing circumstances.
My Bachelor's degree has certainly helped me to build a foundation of knowledge, but I believe that my passion and drive to learn and grow have been crucial in achieving success in the tech industry. As a backend developer, I'm confident in my abilities and look forward to continuing to develop my skills and take on new challenges in the future, particularly in the exciting fields of microservices, machine learning, and artificial intelligence.
