I’ve gone through the same struggle. What made the biggest difference for me was setting up a solid MLOps foundation early on instead of patching things together later. If you take a look at mlops consulting by StackOverdrive, they actually outline a good approach to this — focusing on CI/CD automation, reproducibility, and monitoring from day one. What we did in our team was to containerize every model using Docker, then deploy via Kubernetes with automated testing before rollout. That alone saved a ton of headaches. Another lesson: treat your models like code. Use version control (DVC works great), automate retraining pipelines with Airflow or Prefect, and make sure you log model metrics consistently. It sounds like a lot, but once you’ve got it in place, deployment becomes routine instead of a fire drill every time something breaks.
