Technical capability

A practical stack built around production PHP applications.

I do not describe skills with arbitrary percentage bars. The groups below show the technologies and problem areas I actively use across implementation, debugging, integration, deployment, and maintenance.

Where these skills are applied

Technical knowledge is useful when it supports an end-to-end outcome.

My role often spans several layers: reading existing PHP, adjusting MySQL data flow, extending an API, updating the Bootstrap interface, testing the mobile state, and supporting the production release.

Engineering strengths

The recurring technical work behind the technology list.

Debugging

Tracing symptoms across browser, server, database, API, and environment until the actual failure point is understood.

Integration design

Mapping credentials, request states, signatures, retries, webhooks, and internal records before connecting external systems.

Secure workflows

Applying validation, authorization, output escaping, safe file handling, token checks, and responsible secret management.

Production awareness

Considering caching, query behavior, upload size, mobile networks, background work, logs, and rollback before release.
