Hello, my name is Roman. I am primarily a engineer.

In my childhood, I was quite introverted, preferring to spend all my free time indoors rather than playing around outside with friends. Given that my parents were often absent, I was left to my own, dedicating all my time to two main activities - reading books and delving into the inner workings of things.

As I matured, I held onto these two traits. I continue to harbor a strong sense of curiosity, always delving into new subjects, and whenever I embark on learning something, I make a concerted effort to grasp its inner workings.

Hence, when I claim to be an engineer, I’m drawing parallels to those pioneering scientists who devoted themselves to colossal computers that occupied entire rooms.

• My kids, because this is the most important people in the world for me.
• Go, because this is the most simpled language in the world.
• Rust, because this is the most loved language in the world.
• Typescript, because it's the only one language for frontend developing.
• Postgres, because this is the best universal database in this world.
• Clickhouse, because this is the fastest database for realy large data.

• Angular
• Python
• Tarantool

• Flutter
• Neural networks
• Graph databases
