Switching from DS to SWE will not be very hard for you I dont think. Additionally having the DS background can make you extra marketable, especially for smaller companies where a broader skillset is more valuable. If you wanna get some skills with SWE, I would build & deploy some project. Dont worry about the business side but building a rails or nodejs project from scratch and figuring out deployments etc will give you a lot of answers to interview questions.
