PHP & WordPress Engineering Portfolio

This repository documents my transition from Data Science to Backend Engineering, specifically focusing on the WordPress ecosystem. It serves as a centralized location for my code, experiments, and custom plugins built using the rtCamp technology stack.

Learning Roadmap

Phase 1: The Fundamentals

• PHP 8.x Basics (Syntax, Arrays, Functions)
• Object-Oriented PHP (Classes, Inheritance)
• Security Best Practices (Sanitization, Validation)

Phase 2: WordPress Core

• Understanding wp-config.php and File Structure
• Plugin Architecture & Hooks
• Shortcode API
• HTTP API & Transients (Caching)

Phase 3: Enterprise Engineering (Active)

• Custom Database Tables (SQL) for high-performance logging
• WP-CLI (Command Line Interface) for automation
• Data Migration (Handling bulk data ingestion)

Project Documentation

1. Enterprise Audit Logger (New!)

File: enterprise-audit-log.php | Type: Security Plugin

A compliance tool that creates a custom SQL table (dbDelta) to track user activity, bypassing standard post storage for performance.

Technical Highlights:

• Custom SQL Schema: Uses CREATE TABLE and dbDelta() to manage high-volume log data outside of wp_posts.
• Security Hooks: Listeners for wp_login to create an immutable audit trail.
• Dashboard Widget: Custom UI implementation within the WP Admin for real-time monitoring.

2. Enterprise CLI Bulk Importer

File: cli-bulk-importer.php | Type: WP-CLI Command

A command-line tool designed to handle large-scale data migrations. It reads a CSV file and programmatically inserts posts into the WordPress database with a visual progress indicator.

Technical Highlights:

• WP-CLI Integration: Extends WP_CLI_Command to run scripts directly in the terminal, bypassing server timeout limits.
• Stream Processing: Uses fopen() to stream data line-by-line for memory efficiency.
• UX for Engineers: Implements make_progress_bar() for real-time feedback.

3. GitHub Portfolio Fetcher

File: github-portfolio-fetcher.php | Type: API Widget

A widget that connects to the GitHub REST API to display live repository data.

Technical Highlights:

• Performance Caching: Implements the WordPress Transients API to cache API responses for 1 hour.
• Error Handling: Gracefully manages API connection failures.

4. Cricket Pace Calculator

File: cricket-pace-calculator.php | Type: OOP Logic

A physics-based calculator for bowling speed, re-engineered using Object-Oriented Programming principles.
