Optimize surface-mount technology production line performance through systematic OEE analysis, six big losses reduction, changeover optimization, and first pass yield improvement using TPM methodology and electronics manufacturing standards.

Modern PHP development generalist covering PHP 8.4/8.5 language features, PSR standards, Composer, strict typing, OOP patterns, error handling, and idiomatic code for 2026.

Structured triage protocol for production system failures based on Google SRE practices and observability-driven methodology. Guides engineers through symptom scoping, service localisation via distributed traces, hypothesis ranking, mitigation evaluation, and structured incident documentation.

Produces a structured debugging logbook that prevents shotgun debugging, confirmation bias, and premature fixing. Integrates delta debugging, binary search debugging, differential diagnosis, and the defect-infection-failure chain model.
