Before that, developed and maintained ERP/CRM systems at an outsourcing company for retail and logistics clients — including 1C integration, reporting (Excel/PDF), and heavy SQL/LINQ optimization. Comfortable with the full backend cycle: designing REST APIs, working with PostgreSQL and MS SQL Server (schema, indexing, migrations, query tuning), applying Clean Architecture / DDD / CQRS, writing unit and integration tests (WebApplicationFactory + Testcontainers-style setups), and setting up CI/CD pipelines with GitHub Actions. Implemented Redis caching that cut paid provider API calls by ~55%, and introduced async post-booking processing via RabbitMQ + MassTransit (durable queues, DLX, retry with exponential backoff). Also built a production-grade open-source pet project — VcsDevelop, a Git-like version control system on .NET 10 (content-addressed storage, SHA-256 dedup, MinIO). Holds a Bachelor's degree in Applied Mathematics and Computer Science 🎓 🛠 Stack: • C# / .NET • ASP.NET Core (Web API) • Entity Framework Core • PostgreSQL / MS SQL Server / T-SQL • Redis (StackExchange.Redis) • RabbitMQ + MassTransit • MediatR (CQRS), AutoMapper, FluentValidation • OAuth 2.0 / JWT • Clean Architecture / DDD / SOLID • Docker / Docker Compose • GitHub Actions (CI/CD), Azure DevOps Pipelines • xUnit, NUnit, Moq, FluentAssertions • WebApplicationFactory (integration tests) • Serilog + Seq (structured logging) • MinIO (S3-compatible storage) • Git / GitHub / Git Flow 🗣 Languages: • Russian — native • English — B1 📬 Contacts: • Telegram: [contact hidden] • Email: [contact hidden] • GitHub: [contact hidden] • LinkedIn: [contact hidden]
