Russian FederationWhat I'm looking for
I'm a Software Engineer with over 4 years of commercial software development experience, working with C#/.NET, JavaScript, REST APIs, and relational databases.
My background includes FinTech and MedTech projects, where I've worked on application development, API integrations, asynchronous processing, performance optimization, and data handling using Entity Framework Core, MS SQL, and PostgreSQL.
At my current company, my responsibilities also include commercial Go backend development for a mobile application, JavaScript frontend development, and contributing to product improvements, UI/UX decisions, and release processes.
Earlier in my career, I independently designed, developed, and deployed an internal full-stack JavaScript web application integrated with a laboratory information system. Following its implementation, daily laboratory processing volume increased from approximately 60–80 to over 150 tests.
I enjoy solving practical engineering problems, improving existing systems, and building software that makes a measurable difference.
I'm interested in fully remote Backend, Fullstack, and Software Engineer roles with international teams.
