On top of your data science role, you can consider adding infrastructure and MLOps skills. Your core work might have a fundamental shift from building models to serving them which deals more with infrastructure and monitoring (depending on the organisation).

Machine Learning engineering is in high demand. On the other hand there is a lack of expertise on the market. It is actually difficult to find someone with both expertise in science and engineering. Therefore, if you are an expert on one don't be scared to upskill on the other one and enjoy the challenge!

In a world of so many algorithms getting developed every single day, do not try to master all of them. I suggest to do more of projects, understand the kirks of it and then do your R&D for algo’s available that can suit up your need. With every pro & con of that particular algo, you make your way to the path of optimising your model and enrich your experience; thats when you become an ‘Engineer’, who tries - fails - retries and keeps working on the loop of trying, despite failure or success. A machine learning engineer is the one who is ready to take over the work of data aggregation, data analyst, data scientist, business presentations and documentation work together in the industry along with the technical machine learning knowledge!

Machine learning is a critical component of data science - think of them as a dynamic duo that turn data into super useful insights and make genius decisions. Step 1- Researching and understanding different specializations within ML is a good place to start. Some common ones -Computer vision, NLP, Reinforcement Learning, Recommendation Systems and Time Series Analysis. Step 2- should be assessing your interests and passions - Consider what types of problems or applications within machine learning excite you the most. Think about the projects or aspects of your data science work that you enjoyed the most. Then follow by Step 3 - assessing your current skillset and filling the gaps with courses/ Hands-on Projects.

Engineering is more then theory. First understand all the constraints to the use case, then understand the tech limitations to the models. Only then will you find a solution that actually works in production.

Transitioning from data science to a machine learning role involves more than skill acquisition and project showcasing.
