Thank you so much for your guidance today! I really appreciated how you pushed me to clarify my assumptions and justify my architecture choices. The session helped me connect design patterns with real-world scenarios, and I feel much more confident tackling these kinds of challenges now. Hope to work with you again in the future. I booked this session to strengthen my skills in iOS architecture and real-world system design. The experience was incredibly helpful — the coach asked thoughtful questions, explained tradeoffs clearly, and challenged me to think through design decisions. It gave me a much clearer sense of how to approach complex app features. Really appreciate the structure and quality of the session.
