As enterprise applications continue to serve increasingly global and diverse user bases, architects face the challenge of balancing performance, scalability, and usability—all without sacrificing innovation. In this session, we’ll explore proven strategies to scale and optimize enterprise applications that support millions of monthly active users. Grounded in real-world experience from building high-impact platforms with over 18 million monthly users, this talk will cover architectural patterns, performance tuning practices, and data handling approaches that ensure speed and reliability at scale. We’ll also discuss how a strong Architecture Review Board (ARB) can drive alignment and technical excellence across teams, and how thoughtful product leadership plays a crucial role in prioritizing scalability and long-term sustainability. Together, they help create a foundation for building enterprise apps that can grow with user demand and business needs. This session is ideal for architects, product leaders, and engineers looking to future-proof their enterprise platforms and design for both growth and resilience—regardless of industry or domain.
