Backend engineering, distributed systems, and building reliable software.
I’m a software developer with a strong backend focus. I build systems that stay calm under load: clear interfaces, predictable data flows, good observability, and reliability-first trade-offs.
I work mostly with microservice-style systems and asynchronous workloads—APIs (REST/gRPC), databases (often PostgreSQL), caching (Redis), and automation/deployments (Docker, CI/CD, Kubernetes). I’m also comfortable closer to the metal (embedded / microelectronics background), which helps when debugging real-world constraints and failure modes.
On this blog I share practical notes on modern software development: reliability and resilience (timeouts, retries, backpressure), concurrency and async design (from multithreading to event loops), performance bottlenecks, and the fundamentals that make production systems observable and debuggable.
