performance▌

Identifies and eliminates performance bottlenecks in Flutter apps through systematic profiling and targeted optimization. \n \n Provides a decision tree to diagnose jank on UI thread, Raster (GPU) thread, or both, with specific fixes for each \n Includes integration test templates using traceAction and TimelineSummary to establish performance baselines and measure frame budgets \n Covers UI optimization (localizing state, const constructors, StringBuffer usage) and Raster optimization (replacing

Profile and optimize Python code using cProfile, memory profilers, and performance best practices. \n \n Covers CPU profiling with cProfile, line-by-line profiling with line_profiler, memory tracking with memory_profiler, and production profiling with py-spy \n Includes 20+ optimization patterns: list comprehensions, generators, string concatenation, dictionary lookups, NumPy vectorization, caching, multiprocessing, and async I/O \n Provides database optimization techniques including batch opera

Comprehensive performance optimization guide for Expo React Native applications. Contains 42 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.

Scan C#/.NET code for performance anti-patterns and produce prioritized findings with concrete fixes. Patterns sourced from the official .NET performance blog series, distilled to customer-actionable guidance.

Diagnose and fix performance bottlenecks across React frontends and database backends. \n \n Covers frontend optimization: React.memo, useMemo, useCallback, lazy loading, code splitting, image optimization, and bundle analysis \n Includes backend strategies: N+1 query fixes, database indexing, Redis caching, and API compression \n Provides measurement tools and workflows using Lighthouse, Web Vitals, and webpack-bundle-analyzer \n Emphasizes profiling first, incremental improvements, and continu

Comprehensive Next.js performance optimization covering Core Web Vitals, modern React patterns, and production-grade techniques. \n \n Covers Core Web Vitals optimization (LCP, INP, CLS), image/font optimization with next/image and next/font , and caching strategies using unstable_cache and revalidateTag \n Guides conversion of Client Components to Server Components, implementation of Suspense streaming for progressive loading, and bundle size reduction through code splitting \n Includes Next.js

Caches configuration phase across builds (AGP 8.0+):

High-performance React Native animations and 2D graphics with Reanimated v4 and Shopify Skia. \n \n Covers gesture-driven interactions, spring/timing transitions, layout animations, and Reanimated CSS transitions/keyframe animations without custom worklets \n Supports Skia Canvas scenes with runtime effects, shader uniforms, path interpolation, and animated drawing primitives \n Includes dev-mode tuning panels with sliders for real-time animation config and shader uniform adjustment \n Provides
