À propos de Viktor

I’m a full-stack Developer with over four years of experience, mainly focused on backend development. Currently, I’m working as a full-stack developer on a volunteer project in Paris.
I led the migration of several core services from a monolith to microservices, which reduced downtime and improved deployment flexibility.
I work with TypeScript, React, Next.js, RabbitMQ and CI/CD pipelines.
For the last three years, I’ve been working at a global software company, where I helped develop a parking monitoring system. My work includes designing and building microservices using Java, Spring, Node.js, Docker, and CI/CD pipelines. On the frontend, I use Typescript, React, and CSS to support a responsive user interface.
