Education

2020-04-01 - 2022-03-01

TADSI

/SENA

TADSI (Systems Analysis and Development Technologist). This technology-focused program honed my ability to analyze, design, and develop software systems. I learned systematic approaches to requirements gathering, process modeling (such as UML), and solution design to address real-world problems. The coursework emphasized full-stack development, providing hands-on experience with frontend technologies like HTML, CSS, and JavaScript, as well as backend programming in languages such as Java, Python, or C#. Database management was integral, with practical training in SQL and integrating RESTful APIs for seamless data exchange. The program also introduced DevOps fundamentals, including version control with Git and basics of CI/CD pipelines, alongside quality assurance practices to ensure software reliability. By the end, I was prepared to deliver efficient, user-centric software solutions tailored to organizational needs.
