Welcome to my personal reference repository for solving technical problems across backend development, DevOps workflows, infrastructure setup, and system configuration. This space is designed to document recurring issues, proven solutions, and best practices — so I can debug faster and build smarter.
This repository is a living knowledge base to help me:
- Troubleshoot common and complex technical issues
- Document fixes and patterns for future reuse
- Share solutions with collaborators or the community
- Maintain consistency across projects and environments
- Environment variable management
- Docker and container networking
- Kubernetes deployment and scaling
- CI/CD pipeline configuration
- Database connectivity and security
- Shell scripting and automation
- System-level debugging (WSL, portproxy, SSH tunnels)
This repo includes troubleshooting notes for:
- Node.js, Python, Bash
- PostgreSQL, Redis, MongoDB
- Docker, Docker Compose
- Kubernetes (K8s)
- GitHub Actions, GitLab CI
- WSL, SSH, portproxy, systemd
- VS Code, CLI tools, GUI integrations
- Browse Markdown files for quick reference
- Copy and adapt solutions to your own projects
- Use this repo as a base for your own troubleshooting toolkit
This is a personal reference repo, but feel free to fork it or use it as a base for your own troubleshooting notes. If you spot something worth improving, I welcome suggestions.
