Hey! Just keep coding and writing. Unfortunately, a lot of writers aren’t happy with their works, including me, but there are SO MANY people who will enjoy what you write!
Sometimes, it’s best to watch or read a book based on your genre and if it’s slightly similar to your story even if it’s just the character personality. This will give you a lot of inspo to write!
If anything, maybe step away for a few days and come back. Look at your work with a fresh mind. Sometimes even outline the story plot. So from the start, the middle (climax) the peak (drama) the slop (resolution) and the end. This will help you a lot especially if you have writers block 
doesn’t need to be detailed, just enough for you to see what needs to be done and maybe change it up as you write if you feel like you want a slightly different flow
