Marvelous Kudakwashe Tshuma
Data Scientist
Cape Town
Summary
I am a python systems developer and data scientist with a strong background in mathematics and experience in data analysis, data wrangling, Machine Learning and Deep learning. I am also certified as a Microsoft Data Analyst Associate with extensive working knowledge in SQL. With a set commitment to lifelong learning and continuous professional development, I thrive to be up to date with the latest technologies in my field. Due to several leadership roles acquired in past placements, I am able to integrate and or lead a team in all phases of project development. It gives me great pleasure to evaluate already existing systems and find ways to do things better. It is the thrill of coming up with solutions and improving existing systems that gives me a reason to wake up and face each day with so much expectation. I believe the heartbeat of a developer must be the desire to reduce human effort. My deepest desire then is to leave footprints on the sands of innovation.
