Data layer

DB Design & Optimization

App-layer tweaks won't hide a wrong schema or missing indexes. Clarify the boundary before choosing the build path.

Schema design, indexes and slow-query work alongside PHP apps.

Handover-ready code Clear layout, naming and config so your team can continue.
Frameworks for fit Laravel/ThinkPHP chosen by scenario—not fashion.
Data layer included Schema and query paths designed with the app.

Data-layer issues

These usually show up before a project starts—or right after a rushed launch.

01

Large tables without indexes—list APIs timeout—teams then argue across ownership lines.

02

Poor types hurt storage/compare—it often surfaces only after production impact.

03

Unpaginated full scans—iteration and local integration slow down.

04

Careless cache causes inconsistency—users feel it as inconsistent data or UX.

Access-path-driven design

List hot queries; design indexes/tables accordingly; avoid N+1 in PHP; cache only invalidatable read models. Design tables/indexes from access paths—not giant ER diagrams first. Explain/rewrite hot SQL; add cache when needed.
