What 20 Years of Building Fintech Systems Before AI Taught Me That No Tool Ever Will
The author reflects on their early career in an era devoid of modern development tools, emphasizing the critical importance of system design. First, systems must be designed with failure in mind, ensuring they can handle issues when they arise. Second, developers need to have a deep understanding of every layer beneath their code, including the network, operating system, database engine, and hardware, to quickly diagnose problems when production issues occur. These lessons have left a lasting impression on the author, reminding that even in today's fast-paced technological landscape, foundational knowledge and system design remain paramount.
