DDD - Domain driven design. My entire career pivoted the day I worked with a team that was building a large financial system (ie: multiple teams around the world, hugely complex set of business domains, zero margin for error). The entire approach to code, thinking, and organisation meant that a code base that could easily be a mess at 1/10th the scale, was maintainable and actually increased velocity of the teams over time. It made me realise that technology is rarely a solution. In fact every new language promises a silver bullet, when in reality I've always seen its the approach to writing software and complexity that kills projects. DDD - a sane approach to keeping complex systems simple.
