• I worked in logistics where the main work was SPA. I worked as fullstack engineer there. Java as backend, React.js as front end. Main activity of mine was synchronization between old and new services
• One of the spheres is game-dev. I was working as a backend developer of the game where I mainly used Java. We were solving lots of algorithmic tasks. The architecture was partly microservices and partly monolith
I have used not only in a single language and technologies, but also in many languages and technologies and I've worked in different domains.
The only condition I don't expect is chaotic working process.
