How did Danny transform from a games tester to a successful app developer?

After completing his university degree with high scores in web development, Danny initially struggled with low self-belief, remaining in a low-paid games tester job for a year despite his qualifications. Eventually, he took action by applying for web developer positions and secured his first job, steadily building his skills and advancing to lead roles. Danny's confidence breakthrough came when he won first place in a CSS Off competition against 400 competitors, proving to himself he could achieve success. This led him to create his first app—Speed Distance Time Calculator—which immediately generated passive income. This success enabled him to build multiple apps, ultimately creating enough passive income to quit his job and focus full-time on his own products.
