I have been working in IT for over 20 years, always committed to providing quality service to end-users and customers. I have been fortunate to have diverse professional experiences in software development, team leadership, pre-sales, and product management. Since the birth of my daughter, I have been even more inclined to do meaningful work and switched to healthcare IT. Additionally, I co-founded a medical practice, run regularly, and cannot resist doing DIY projects and home improvements.
