Ask HN: Tools for Engineer struggling to design beautiful products

I am a backend software developer. I have always struggled to convert my ideas (of apps, SAAS, websites etc.) mostly because my design sense is poor, I lack expertise in HTML/CSS/Photoshop and I struggle to make changes to templates without messing up their responsiveness and aesthetics. I can code well but I can't design. I am looking for better ways, where I can express my design in code(?). What tools does others here use to design websites? How can I quickly and with less learning curve start designing websites better? I truly suck at it and have struggled quite a lot in the past. Any help is appreciated. Looking for tools, libraries etc that can help me be more coder and less designer to design websites. Side Note: I have a sense of aesthetics and good UI/UX. I know what I want to design but could not master usual tools to design the same.
