Backend application engineering · Relational data
I build and repair PHP features across request handling, MySQL or MariaDB state, validation, permissions, APIs, templates, and production hosting—especially where the visible bug is caused by the interaction between code and data.
Senior PHP & Backend Developer
Focused PHP, MySQL & MariaDB capabilities
Each capability is scoped against the installed version, hosting, current behavior, and surrounding customizations before implementation begins.
Implement PHP modules and business rules that fit the existing framework, platform, request lifecycle, users, and deployment environment.
Work with relational data as part of user, content, payment, platform, and administrative workflows.
Plan agreed data changes alongside code, defaults, existing rows, deployment sequence, and rollback context.
Trace missing, inconsistent, duplicated, unauthorized, or unexpected application behavior back through queries and stored state.
Coordinate related application updates for payments, subscriptions, uploads, authentication, or administrative actions where partial state matters.
Connect relational records to validated REST or AJAX endpoints and clear frontend success, empty, error, and permission states.
Clear service boundaries
These boundaries preserve the difference between evidenced PHP, MySQL & MariaDB work and a broader service that has not been claimed.
This expertise focuses on MySQL and MariaDB as part of PHP products. Dedicated database administration, clustering, replication, disaster recovery, and high-availability design require separate infrastructure scope.
Query investigation can identify application bottlenecks, but no speedup, throughput, row-count, or load result is claimed without measurements and a defined workload.
Backups, access controls, data sensitivity, migration order, maintenance windows, and rollback expectations must be agreed before material production changes.
PHP, framework, MySQL or MariaDB version, SQL mode, charset, extensions, and vendor-script requirements are reviewed rather than assumed interchangeable.
PHP and MySQL are directly represented throughout the project record. MariaDB experience is confirmed without invented scale, performance metrics, clustering claims, or separate case-study outcomes.

PHP, MySQL & MariaDB delivery process
Credentials are requested only after the scope and access requirement are understood, using an agreed secure channel.
Identify the user action, PHP entry point, queries, tables, relationships, permissions, expected state, and actual failure.
Review relevant PHP, configuration, schema, representative sanitized data, logs, and query behavior before proposing change.
Define migrations, defaults, compatibility, backfill if needed, deployment sequence, tests, and rollback context.
Change the required PHP, queries, validation, data state, API, or interface without unrelated schema churn.
Test permissions, empty data, invalid input, existing rows, failures, nearby workflows, deployment, and clear handover notes.
