I write about what I build and what I learn. Heya! 👋 I love helping people, and one of the best ways I do this is by sharing what I learn and build. I started as a pharmacist at a tertiary hospital in Northern Ghana, where I saw how much technology could improve healthcare. That sparked my interest in digital health. I taught myself to code, then joined the ALX Software Engineering program, which became a turning point. I went on to complete a Master of Health Informatics at the University of Toronto. Today I am a software and AI engineer and a health informatician, and I practise remotely as a Digital Health Pharmacist. I combine clinical experience with technical skills to build tools that solve real problems in health and beyond, and I write here about what I build and what I learn. ## Responses 8 Markdown supported · ⌘↵ to post [Naol Solomon](https://hashnode.com/@NaolSolomon) [Sep 15, 2023](https://hashnode.com/posts/building-a-simple-shell-in-c-part-4/6374768e5d21d5e9dbd004a2/comment/6503b181770802e8a4add026) it is really amazing [Adegbite Seyi](https://hashnode.com/@Adegbite0382) [Sep 8, 2023](https://hashnode.com/posts/building-a-simple-shell-in-c-part-4/6374768e5d21d5e9dbd004a2/comment/64fa94b1c035cd988c325e0c) is this the last part of the series Dr. [Julius Ibe](https://hashnode.com/@juliusIbe) [Jul 20, 2023](https://hashnode.com/posts/building-a-simple-shell-in-c-part-4/6374768e5d21d5e9dbd004a2/comment/64b939b9af9957de87410c3a) Hello Dr. Ehoneah, I enjoyed this simple shell series a lot.
