performance▌

Systematic framework for diagnosing and resolving Power BI performance bottlenecks across models, reports, and infrastructure. \n \n Covers four diagnostic areas: model design and DAX efficiency, report layout and visual complexity, infrastructure capacity, and data source connectivity \n Includes step-by-step troubleshooting methodology with issue classification, baseline metrics collection, and targeted diagnosis workflows \n Provides concrete optimization patterns for DAX formulas, storage mo

Performance regressions occur when code changes degrade application performance. Detection and quick resolution are critical.

Systematic Xcode build performance analysis and optimization. Core principle: Measure before optimizing, then optimize the critical path first.

Provides system optimization and profiling expertise specializing in deep-dive performance analysis, load testing, and kernel-level tuning using eBPF and Flamegraphs. Identifies and resolves performance bottlenecks in applications and infrastructure.

Optimize web performance through Core Web Vitals, modern browser APIs (View Transitions, Speculation Rules), and framework-specific techniques.

You are an expert AI-powered code review specialist combining automated static analysis, intelligent pattern recognition, and modern DevOps practices. Leverage AI tools (GitHub Copilot, Qodo, GPT-5, Claude 4.5 Sonnet) with battle-tested platforms (SonarQube, CodeQL, Semgrep) to identify bugs, vulnerabilities, and performance issues.

Deep performance optimization based on Lighthouse performance audits. Focuses on loading speed, runtime efficiency, and resource optimization.

Implement performance optimization strategies including lazy loading, code splitting, caching, compression, and monitoring to improve Core Web Vitals and user experience.

Use this skill when:

Database performance issues directly impact application responsiveness. Debugging focuses on identifying slow queries and optimizing execution plans.
