It started with a sixth-grade student being enrolled in a web design & development course, making strides, completing several internships, learning a handful of skills in the span of 6 years, and ending up at Habib University. With this new beginning, I co-founded a product-based startup and took tens of electives exploring various fields in computer science, mathematics, and environmental studies. Throughout my learning and professional career, I have been highly regarded for my informal communication skills, quick learning ability, and under-pressure problem-solving skills.
