Skills
A capability map backed by project work.
No percentage bars and no inflated labels. These groups describe what appears in case studies, code, testing, and documented operations.
Demonstrated means the capability appears in published project evidence. Developing identifies the next layer of knowledge without presenting it as production experience.
Linux and infrastructure — demonstrated
- Ubuntu and Debian environments
- KVM virtual machines and Docker containers
- Nginx, HTTPS, DNS, services, and persistence
- Access troubleshooting and operational health checks
ERPNext and Frappe — demonstrated
- Native Bench and Docker deployment paths

- Optional application discovery and installation
- Updates, backups, restoration, and verification
Automation and delivery — demonstrated
- Bash workflow and command-line interface design
- Git and GitHub collaboration
- Formatting, static analysis, and CI gates
- Checksums, signed assets, update safety, and rollback
Security and recovery — demonstrated
- SSH and web-service hardening concepts
