Who is the Senior App Developer Mentoring For?
- Lack of self-confidence: You don't know how you should feel about your code which lowers your self-confidence about your skills.
- Career change: You're looking for a better job, but lack many core skills of modern Android / KMP development.
- System-level thinking: While you may understand specific technologies, you struggle with understanding trade-offs and making the right decisions when the answer is not black and white.
- Juniors & mid-level devs: You understand how to build an app, but don't understand it deeply and simply lack practical experience.
- Looking for promotion: You know there's more to reach at your current company, but you lack what's needed to get there.
- Feeling overwhelmed: You feel left behind by all the fast changes in the AI ecosystem and want to learn what matters ASAP with a clear structure.
- Modernizing rusty skills: You know how to develop apps the old way, but you've lost track of the modern Android tech stack.

Philipp Lackner has over 14 years of experience in the software field. Over the past years, he built a following of over 250,000 developers on social media who trust his work. With over 25,000 sold copies of his courses and 1,000h+ spent for teaching Android concepts, he already helped hundreds of thousands people to learn practical skills they can immediately apply.
He has a degree in computer science, however it didn’t go as expected. The amount of theory that was taught in university made him think about a better approach to learn what is really needed in the real world. Over time, Philipp found mentors who taught him exactly that in a practical setting. That was the game changer for his career.
After having worked for dozens of companies around the globe as a consultant, Philipp now wants to teach other Kotlin developers what really counts for becoming an outstanding developer in today’s competitive industry.
