🧠 About me:
Worked in teams of different sizes and built projects from the ground up — most recently a B2C travel booking startup where I designed the core booking module, an aggregator over multiple external providers, and OAuth 2.0 authorization. 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).
