Backend & DevOps Engineer focused on async diagnostics for Java backend, CI/CD, Kubernetes, deploy issues, and backend automation.

I work async-first and text-only: no calls required for small technical tasks. I work from written requirements, logs, configs, repositories, and clear deliverables.

• Java backend error fixing and debugging: Spring Boot, Quarkus, REST APIs, integrations
• Build/runtime diagnostics: Maven, Gradle, JVM services
• Container and runtime setup: Docker, Docker Compose, Kubernetes manifests
• VPS/Linux/Nginx deploy support
• GitHub Actions / GitLab CI setup
• Backend/DevOps diagnostics and short written reports
• Production/server rescue: 500/502/504, app not starting, broken deploy
• Backend automation workflows when relevant: Python/Playwright, TypeScript/Node, worker queues, and AI integrations

• PR/fix or config changes
• Run commands
• README/runbook
• Short handoff note

• Spring Boot + Docker deployment diagnostic
• Local-first Web of Science automation
