TL; DR: Since 2019 I’m an Engineering Manager at Freeletics.
Strive for excellence, knowing that it’s a way paved with failures. Approach problems with a systemic mindset: your team is part of a bigger team.
People come first, help them shine in what they excel, provide them with the chances to be challenged so they can grow and learn from the uncomfortable.
Be transparent, honest, and direct. Bring joy. Be vulnerable and be of example. Ask for feedback for yourself, people will be open to hear from you next.
