Backend Developer

Worked on a CRM system for automating recruitment processes for a European B2B client. Part of an 8-person Scrum team.

Developed the candidate management module (CRUD, filters, access roles) using C# and .NET Core (migrated from .NET 6 to .NET 8)
Built REST APIs for the admin panel and a notification microservice with SMTP and Telegram API integration via RabbitMQ (using MassTransit, retry with Polly)
Optimized PostgreSQL queries with Entity Framework Core for faster analytical reports
Wrote unit and integration tests (xUnit, NSubstitute, FluentAssertions, ~60% coverage)

Achievements:

Improved analytical report speed by 25% through query optimization and Redis caching
Reduced notification delivery errors by 20% and increased delivery speed by 35%
Reduced deployment time from 10 to 3 minutes using GitHub Actions and Docker
