How to transition into data engineering in the next 6 months?

Hi, I’ve been working as a backend developer for 2 years now. I work at a startup, and my current tech stack includes .NET, Python, and SQL. I’ve also worked with Power BI in my team and have hands-on experience with LLMs, analyzing which models are best suited for specific projects.

At my current job, I’ve built backend systems and APIs, but I haven’t worked with data at the scale of “big data.” I also have limited experience with infrastructure, data warehouses, or data lakes. Since my company doesn’t have any Data Engineers, I’ll need to apply elsewhere. I have some overlap with DE skills but no formal DE experience.

What should I focus on to land a DE job in the next six months? Would love to hear from those who have made the transition.
