I designed the major part of server-side during one of the company's project. 

I rewrite another project from CoffeeScript and callbacks to TypeScript and pormises(async/await). It was hard because a great part of legacy code was unsuitable for new database and I must not rewrite it but create from zero
I develop server-side of company’s projects with node js. I often write SQL  queries to PostgreSQL database. Sometimes I also work with front-end on React.
My achivements:
During one of the company's project, I designed the major part of server-side. I participated in the database's design and made some changes after. 
I also created almost all of end-points. 
On another project, I developed a server which used the tls protocol. I based on legacy code which had been written on CoffeeScript and callbacks. My duty was to rewrite it on Typescript and promises and also it must be relevant to our new database. So I can say, that I've designed it from zero because a major part of the old code was unsuitable.
don't want to work a lot with front-end.
I don't care about the company's size but I hope that there will be a code review's and I will have an opportunity to improve my skills. And not a lot of legacy code, please.
