About Andrey
I help diagnose and fix focused Java backend/runtime/deploy issues with async-first delivery.
I work from written requirements, logs, configs, repositories, reproducible steps, and clear acceptance criteria.
Services:
- app not starting after deployment;
- Spring Boot and Quarkus troubleshooting;
- Maven/Gradle build/runtime issues;
- Docker/Compose/Kubernetes issues;
- VPS/Linux/Nginx/SSL deploy support;
- GitHub Actions / GitLab CI build/deploy failures;
- PostgreSQL configuration and connection issues;
- 500/502/504 troubleshooting;
- AI backend systems / agent workflow reliability when the issue is repo, runtime, Docker, CI/CD, workers, queues, logs or runbooks;
- backend/DevOps diagnostic with a written report.
Typical delivery:
Written diagnosis, root-cause notes, PR/fix or config change, run commands, README/runbook, and short handoff note.
AI note:
I do not sell vague AI strategy or prompt-only consulting. I can help when an AI-enabled backend, agent workflow, OpenAI/LLM integration or browser automation system needs to be made more reliable, deployable and maintainable.
