Overview
TROUBLESHOOTING ACROSS DOMAINS
Hands-on experience diagnosing and repairing consumer electronics, vehicles, appliances, and industrial equipment across 30+ distinct product categories. The work spans electrical systems, mechanical components, embedded software, and integrated assemblies — each requiring a different diagnostic approach and specialised knowledge.
The core approach is systematic first-principles analysis — understanding how a system is supposed to work, where it's failing, and why. That methodology applies equally to 50-year-old industrial machinery and cutting-edge consumer electronics, and it compounds with every repair.

HAIR STRAIGHTENER RESISTOR REPLACEMENT
A failed resistor on a hair straightener — diagnosed with a multimeter, repaired at board level, and returned to service. The video covers the full process: fault isolation, soldering, and reassembly.
Methodology
SYSTEMATIC ANALYSIS APPROACH
Disassemble & Document — Systematic teardown preserving component relationships and operational context.
Analyse & Diagnose — Study schematics, trace signals, and apply first-principles fault analysis to isolate the root cause. Multimeter testing and fault isolation over guesswork.
Source & Execute — Validate replacement parts against original specs, then solder, adjust, or calibrate with precision.
Validate — Comprehensive testing under normal and stress conditions to confirm reliability before returning to service.
