Real cases
Documented work on real systems. Every card distinguishes measured diagnostics and independently verified results from later owner-reported outcomes. Private names, credentials and infrastructure identifiers remain out of the public case summaries.
Finding service failures on servers with normal CPU and disk capacity
Real diagnostics on two anonymized environments showed low CPU load and 30–32% root disk usage while both systemd managers reported degraded status. The next step was identifying failed units, not guessing at a repair.
Improving a home router and documenting an internet-speed shortfall
A Keenetic diagnosis recorded roughly 45–49 Mbps on a paid 100 Mbps connection. The owner later reported fixing wireless-signal issues, disabling unused services and achieving better router performance. The speed gap supplied evidence for an ISP complaint.
Recovering Lightroom after repeated editing crashes
Crash logs identified repeated stack-overflow failures. GPU-acceleration and catalog checks did not resolve them; the owner reports Lightroom working again after moving to a newer version.
Deploying a GitHub project with one AI request
A user named a GitHub-hosted project in the AI conversation and asked to install it on an existing server. The project was deployed without turning the user into a copy-paste relay between chat and SSH.
Reaching home devices from the office
Requests from an office Mac changed from timeouts to web responses from a home router and an ASIC. The existing VPN was shared through a Linux gateway without changing the Mac's routes.
Restoring broken GPU telemetry
A graphics card worked and displayed video, but monitoring tools returned 0 °C, invalid clocks and missing fan data. The fault was isolated to a mixed software stack and verified under load after repair.
Migrating a production server safely
A live application stack was moved from an older host to a new server while preserving public endpoints, authentication, TLS, rollback and operational continuity.
