Software that is calm to run and easy to change

My name is Alim, I am 23. I am a full-stack developer focused on backend and cloud infrastructure.
I started programming at school and earned a Bachelor's degree in Software Engineering from Sevastopol State University in 2024, and completed my Master's in 2026. My first paid projects were websites and plugins for freelance clients in 2018.
Since 2022 I have worked at TenenGroup Technologies on a multi-brand e-commerce platform. Most of my work is .NET and PostgreSQL services that talk over AWS SQS and SNS, run on Kubernetes with Helm and Terraform, and have React back-office interfaces on top.
I want my code to be easy to read and maintain — a year from now, and by someone else.
I use AI in my daily work and build an AI pipeline into the SDLC.
