About

Cloud-native .NET backend engineer. I build and run production systems for data-intensive and event-driven workloads: high-load services, time-series data, and messaging. I design and operate C# and .NET services with PostgreSQL and TimescaleDB, using RabbitMQ, Kafka, and Pub/Sub on Google Cloud.

I've worked in enterprise and startups, owning backend end-to-end: API design and data modeling, CI/CD and deployments, monitoring and on-call. I care more about systems that stay predictable under real traffic than about architecture diagrams.

I use Google Cloud (and AWS or Azure when needed), plus Python, JavaScript, and Bash for automation and pipelines. What I enjoy most is turning messy, real-world data into reliable, observable systems that teams can trust.
