Building backend systems focused on scalability, reliability, concurrency, and real-time processing.
I'm a Backend Engineer primarily working with C# and .NET.
My main interests are:
- Distributed systems and microservices
- Event-driven architecture
- Kafka and RabbitMQ
- Real-time systems
- Concurrency and rate limiting
- Caching and distributed state
- AI / LLM infrastructure
- Reliability and resilience
I enjoy working on problems involving concurrency, distributed communication, failure handling, and system scalability.
A provider-agnostic API key pool for .NET applications that work with multiple LLM API keys.
Designed around practical problems that appear when operating multiple API keys:
- Key rotation
- Quota-aware cooldown
- Per-key concurrency limits
- Health tracking
- Rate limiting
- Resilience and failure handling
The goal is to provide a reusable infrastructure component that can sit between an application and multiple LLM providers.

A real-time truck dispatch system built around event-driven architecture.
The project explores reliable asynchronous processing together with real-time operations.
Key components:
- Apache Kafka for event-driven communication
- Transactional Outbox Pattern
- Redis GEO for vehicle location tracking
- SignalR for real-time updates
- Reliable Kafka message processing
- Dispatch and tracking workflow

Trạm Chữ is a web platform for reading translated novels.
The platform uses an automated translation workflow to process Chinese web novels into Vietnamese and publish the translated content for readers.
