Position: NodeJS / Typescript backend developer
Category: Node.js
English level: fluent
Years of experience: 7

I optimized a lot (and I mean it ) of SQL queries, identified and fixed a lot of bottlenecks. Overall, I enjoy doing architecture stuff and profiling/fixing code so it can work faster.
For almost 10 years of work, there have been a wide variety of projects, from an online store on Ruby on Rails to a B2B chat on NodeJS. Not only do I close tasks in Jira, but I also try to delve into the business domain of the customer. I have experience in direct communication with customers and I did some demo sessions.
An interesting project. Adequate management.
I do not like and almost do not know how to do front-end. I love Typescript and don't like JS projects without it.
