I've been working as Software Testing Engineer (QA) for almost 1.4 years now. I want to move to development though. I find development much more interesting. I plan on giving the OCP exam, improve my problem solving skills and learn spring boot. For spring boot I've enrolled myself to a course on udemy.
I can spare around 6-7 hours daily to work on these stuff for the next 6 months. I'll start looking for job in March or April. Any advice on what more I could or should learn or any advice in general?
My best advice.. aside from studying and taking the cert... find a friend who can help get you a job as a developer, even if its just a side job.
Switching from testing to development, while possible, is not common in my experience. For example, you might go in for a job interview for development but when they see you have testing experience they shift you to testing thinking you'd prefer to do what you know. In order to get a development job, you have to play down your testing experience and play up your development experience.
