Diagnosis

A growing record of how I find causes, test evidence, and turn messy technical problems into working fixes.

camera

Camera Diagnosis

Optics, sensor behavior, firmware symptoms, storage failures, power paths, and repeatable tests for real camera problems.

Status
planned
Evidence
photos, logs, tests

hardware

Board and Device Faults

Power, USB, display, embedded Linux, boot chain, and mechanical issues where the fix depends on both circuits and software.

Scope
embedded
Method
measure, isolate, verify

systems

Infrastructure Incidents

Network reachability, Kubernetes services, storage, tunnels, DNS, certificates, and deployment failures traced from symptom to cause.

Scope
ops
Method
trace, reproduce, recover

software

Tool and Workflow Breakage

Build failures, data mismatches, browser behavior, automation gaps, and small tooling bugs fixed with a clear proof path.

Scope
apps
Method
reduce, patch, test
01 Observe

Capture the symptom without hiding uncertainty.

02 Separate

Split hardware, software, environment, and user-flow causes.

03 Prove

Use a repeatable check before calling the fix done.
