"Hi there! My name is Hemstone Ouma and I am a computer scientist with a strong background in handson experience skills such as programming, sofware development and testing to name just a few. I have a degree in computer science from Dedan Kimathi University of Technology and a Masters degree from the University of Nairobi in Business Education. I have spent the past 6 years working in the field, gaining a wide range of skills and knowledge. In my current role as a programmer, I have had the opportunity to work on a variety of projects and have developed a strong understanding of several programming languages such as python, java, C++, C# and Javascript.
In addition to my professional experience, I also have a passion for teaching and helping others to learn. I have experience as a tutor, both in a formal setting and on a oneonone basis, and have a proven track record of helping students to succeed. I believe that with the right guidance and support, anyone can learn and excel in computer science.
I am excited to bring my skills and experience to a new opportunity and am always looking for ways to make an impact and grow as a professional. I am confident that my handson experience as a computer scientist and tutor make me a strong candidate for any role and I am excited to see where my career will take me next.
