## About

```text
At RTS, I co-develop production e-wallet features across Flutter clients and ASP.NET Core backends for a multi-bank product with 10+ branded variants. I work with SQL Server, Redis, and RabbitMQ, and support CI/CD and deployments.

I also assessed P2P transfer security at RTS, identified nine confirmed vulnerabilities, and delivered a remediation report covering transaction integrity and authorization risks.

At Modern Soft, I developed ASP.NET Core APIs backed by Oracle stored procedures and integrated RabbitMQ for asynchronous processing. I also built and released Flutter apps for debt collection and field marketing, including GPS verification and native Android integrations.

In freelance projects, I built and released a Flutter delivery and commerce application and developed LLM/RAG integrations with the Anthropic API and ChromaDB. My projects also include an ASP.NET Core analytics backend and an LLM-driven security assessment workflow.
