Now

I build reliable backend systems at Qualgo. Currently learning Swift and applied LLM engineering.

Projects

A hands-on environment for a Go HTTP service, bringing metrics, logs, and traces into one coherent observability stack.

Observability · Go

A backend lab exploring device messaging, asynchronous work, and time-series data in a reproducible environment.

Messaging · Backend systems

A Go reference service exploring reliable event publication across PostgreSQL and Kafka with the transactional outbox pattern.

Go and Python services, APIs, concurrency, data access, and interfaces that remain clear as a system grows.

Asynchronous workloads, delivery guarantees, idempotency, and designs that account for failure paths.

Metrics, logs, traces, and operational signals that help explain what a service is doing when it matters.

Backend infrastructure for classification and threat-detection workflows, with reliability built into the feedback loop.
