Roman Andreyanushkin

I've built and maintained web applications across Angular, C#, and REST APIs, including request-status interfaces and XML validation services at the Federal Institute of Industrial Property.

At KvartalCity, I gathered requirements, prepared technical specifications, designed application architecture, and developed both backend and client-side functionality. I also supported testing, bug fixes, refactoring, and optimization throughout the product lifecycle.

I've delivered Angular applications integrated with CRM systems at Nikfort, creating reusable modules, components, UI kits, and adaptive layouts with Angular Material and RxJS.

Outside my core roles, I've completed projects for real-estate recruitment, e-commerce, client-list management, and pump sales using Angular, .NET Core, PostgreSQL, SQLite, and GitHub. I'm open to learning, growth, new technologies, and collaborative Agile teams.
