Possible challenges before choosing this path.
ML Engineering requires software engineering, ML theory, deployment, cloud, data pipelines, monitoring, and production troubleshooting together.
Poor, delayed, biased, or unstable data can break model performance even when engineering is strong.
Model quality can decline over time when real-world data changes, so monitoring and retraining are important.
ML services may need fast fixes when APIs fail, latency rises, predictions break, or deployment pipelines fail.
MLOps tools, cloud ML platforms, model frameworks, and deployment practices change frequently.
Stakeholders may expect ML to solve problems even when the use case lacks enough data, clear labels, or measurable value.
