What language/framework are you learning? Use whatever you learning to solve the issues in your father's practice. That is the best way to start. Look for opportunities where practice is doing something manually repeatedly. Try to figure out if there is a way to automate the process and perform more efficiently. Look for incremental improvement opportunities in the processes. Pick small problems, build small solutions, demo to users in the practice, improve based on feedback, roll out quickly. Don't try to change the process, users are already familiar with. Small quick wins will snowball into bigger opportunities. Don't take on more than you can handle.
