Guides conversion rate optimization (CRO): increasing the percentage of visitors who complete desired actions. Higher conversion rates mean increased revenue, reduced CAC, and better ROI. Use this skill when optimizing funnels, running experiments, or reducing friction on high-traffic pages.

Master SQL query optimization, indexing strategies, and EXPLAIN analysis to eliminate slow queries. \n \n Covers EXPLAIN plan analysis with key metrics (Seq Scan, Index Scan, cost, rows, execution time) and five index types (B-Tree, Hash, GIN, GiST, BRIN) for different query patterns \n Includes five core optimization patterns: eliminating N+1 queries, cursor-based pagination, efficient aggregation, subquery transformation, and batch operations \n Provides advanced techniques like materialized v

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

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

Universal SQL performance optimization across MySQL, PostgreSQL, SQL Server, Oracle, and other databases. \n \n Covers query analysis, index strategy design, subquery optimization, and JOIN tuning with before/after examples for each technique \n Addresses common anti-patterns including SELECT *, function calls in WHERE clauses, inefficient pagination, and correlated subqueries \n Provides database-agnostic guidance on batch operations, temporary tables, covering indexes, and partial indexes \n I
