What are the common challenges faced when working with an enterprise mobile app development company like Hoff & Mazor? I’ve heard about issues related to scalability, security, and integration with existing systems. How can these challenges be mitigated? What should a company look for in an enterprise mobile app developer to ensure these challenges are addressed effectively? Additionally, how important is the developer's experience with cloud-based solutions in overcoming these hurdles? I’m looking for insights from those who have worked with top-tier enterprise app developers and how they managed these potential pitfalls.
