Kamil Betkowski

Backend-focused developer working mostly with Java and Spring Boot. Before software I spent time in networking and IT infrastructure — servers, virtualization and monitoring — and that's where my interest in backend systems, observability and reliability comes from.

I like building projects end to end and understanding how the pieces fit together: the domain model, the database, messaging, security and deployment.

Currently building my portfolio and open to junior/mid Java backend (and fullstack) roles.

Featured projects

  • incident-manager — device monitoring and incident escalation. Two Spring Boot microservices talking over Kafka, hexagonal architecture, JWT, Prometheus/Grafana.
  • induo-house — full-stack real estate platform. Java/Spring backend + Next.js frontend, JWT auth, Testcontainers, Dockerized.
  • ActiveZen — my engineering thesis: a cross-platform fitness app built with Flutter and Firebase.

Tech I work with

Java · Spring Boot · PostgreSQL · Kafka · Docker · JUnit / Testcontainers · Prometheus / Grafana · some React / Next.js · Linux & networking background
