About Jonathan Khalilu Mansaray

As a kid, I have had a deep passion for math and numbers. Teach me a game involving numbers, and I will fall in love for it. I ever wanted to use the love I have for numbers to make an impact in the world. Throughout high school in Sierra Leone, I have come to play with numbers in class, especially when often I'm appointed to lead a class. I love that desire to keep track of attendance for every school session. That build my inner mind to love data, metadata. One day, I asked my principal, what type of career I should go in for, especially when you loved playing with figures and track records. He said, data scientist career will be a good fit for you, boy. I envisioned the passion I have, and someday I will become a data scientist as a career where I can help improve efficiencies in entities process. I have been looking for opportunities to improve my data analysis skill, especially in python programming, R and SQL whether in the classroom or outside of the class. I want to continue to apply the skills I have learned and more significantly to acquire new skills by learning from other people's experiences. Note: I love serving humanity, especially my fellow humans in any little way I can. I have served in a voluntary missionary service for the Church of Jesus Christ of Latter-day Saints where I have the opportunity to preach the gospel in Nigeria. I love the people I served and have been involved in humanitarian services in the church. I love adventure, and I love exploring new cultures and customs of people. And I love working with innovative people who are eager to pursue hard tasks in the computing field. I'm a lifelong learner, always seeking new knowledge and insights through reading articles and exploring new ideas. My goal is to inspire and uplift others, and I believe that together we can create a brighter future for all.Learning and Relearning to Become Specialist on: ● Data Analysis ● R: Programming ● Python ● Data Entry Clerk ● SQL, MySQL, and MS Access ● PC Hardware Technician● Web developer with WordPress, Ipower, Hostinger, and Wix ● Web Designer with Plug-ins and Elementor, Dribble● Tabulae, Ms. PowerBI, Excel, Spreadsheet. ● React● Graphic Designer with AI, cutout.pro, Canva, PosterMyWall, and Adobe Photoshoot.
