Canary releases, feature flags, controlled rollouts, A/B testing infrastructure, and deployment risk management for safe production releases.

Generates structured, blameless post-mortem documents from incident data following Google SRE methodology. Enforces psychological safety principles, validates action items for owner and deadline completeness, identifies systemic root causes rather than individual blame, and produces publication-ready post-mortems with timeline reconstruction, impact quantification, contributing factor analysis, and trackable corrective actions.

Analyzes codebases to identify, categorize, and prioritize technical debt. Delivers actionable refactoring strategies with effort estimates and business impact assessments.

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. Reduces Mean Time to Resolution by enforcing systematic investigation over ad-hoc troubleshooting.

Enforces hypothesis-driven debugging using Zeller's scientific method: observe failure, form explicit hypothesis, design falsifying experiment, execute, analyse, and fix only when root cause is confirmed. 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.

Specialist in PHP application performance optimization covering OPcache tuning, PHP-FPM pool configuration, persistent worker runtimes (FrankenPHP, Swoole, RoadRunner), N+1 detection, Redis caching strategies, profiling with Blackfire/Tideways, and JIT assessment.
