LARAVEL CRM / PERFORMANCE

Replacing an expensive retrieval path without rewriting the business logic.

A mature CRM grid had become painfully slow. The implementation relied on expensive database views and relationship-heavy retrieval paths. The work identified what the screen actually needed, replaced the slow path with more direct data access, and preserved the filtering and business behavior users already depended on.

QUERY / LATENCY 300ms → 133ms measured with EXPLAIN ANALYZE

MYSQL / QUERY PATH

Cutting expensive database work without changing the result contract.

A frequently used query path was doing substantially more join and deduplication work than the result required. EXPLAIN ANALYZE exposed the expensive path, allowing the access pattern to be narrowed while keeping the output the application expected.

CHANGE / RISK LOWER incremental extraction

INHERITED LOGIC / REFACTORING

Moving business logic out of expensive legacy structures without a clean-room rewrite.

Business rules were spread between controllers, database views and presentation code. The work isolated reusable logic incrementally and reduced dependency on expensive database abstractions while preserving the output expected by existing screens.
