Yes, you can. I expect it will be a little bit hard to get that first job, but once you have experience it will get easier and easier to get better jobs. You need to practice practice practice coding. The best way is just to code some things that are interesting, then work your way up to doing some practice problems. Interviewing varies widely among companies. Some places only want to hire people that are experts in some tech they are using (say a js package), others want to hire people that are generalists, or have worked on mostly frontend - ui, or backend (not ui). Some places want people who can learn anything. There's no uniform thing. Most companies in the US would not consider you for a senior coder, unless you were very very advanced in some aspect of cs. Since you don't have much experience, you could look for an introdutory role. I don't know about signapore, but in the us because of the huge demand its generally easy to find a starting programming job. You could also look for a job that takes advantage of your dev ops/admin background while have some easy programming required, but you'd want to make sure it was really a job that had programming. Good luck! I'm 50+ and have many years of experience and have no shortage of jobs. Just program, try for an hour a day if you are still working in your admin job, and in a few months you'll be much more fluent.
