Projects & Impact

Deep, real-world web systems: custom PHP platforms, integrated WordPress content, secure internal tools, and responsive public-facing sites built to solve business problems for Nigerian and remote clients.

Each section below is a self-contained project breakdown. The first and most comprehensive is Jobnet.ng, covering architecture, user flows, AI-enhanced matching, and technical implementation. Subsequent segments cover adjacent integrations and other client work.

Jobnet.ng Live

Overview

Jobnet.ng connects employers with job seekers through a dynamic portal built primarily in procedural PHP with JavaScript enhancements. It exposes three main user roles: job seekers, employers, and administrators. The platform is mobile-responsive, SEO-aware, and incorporates intelligent behavior through an AI-assisted matching engine that surfaces suitable opportunities and candidates.

Interactive Demo

This short demo shows key user flows on Jobnet.ng for seeker job discovery & application, employer posting & shortlisting. Sensitive admin screens are omitted per NDA.

Technical Architecture & Implementation

Core Stack

Procedural PHP served as the backbone for business logic and routing, with MySQL powering relational data (users, job posts, applications, status logs). Front-end interactivity used vanilla JavaScript enhancements and progressive enhancements to keep the interface responsive across devices. SEO was baked into the server-rendered job detail pages with clean URL structures and metadata.

Matching Engine & AI Integration

A hybrid matching system combines rule-based logic (keywords, location, category) with external AI-assisted relevance scoring to surface recommended jobs to seekers and highlight qualified candidates to employers.

Experience

  • Seeker Experience: Prioritized listings, saved profiles, application pipeline, contextual cues (e.g., “Recommended for you”).
  • Employer Experience: Job creation/management, candidate summaries, shortlisting, internal fit scores, bulk operations.
  • Admin & Confidential Operations: Role-based access, activity logging, moderation tools (private).
  • DevOps / Deployment: VPS with backups, simple CI-like deployment, logging, health checks, caching.
  • Security & Data Integrity: Hardened sessions, prepared statements, server-side validation, rate limiting, access controls.
  • Tools & Ecosystem: PHP (procedural), MySQL, JS, HTML/CSS, AI APIs, custom PHP modules, analytics.
  • Performance & SEO: SSR, minification, progressive loading, structured data, mobile-first.

Impact & Outcome: Delivered a localized job marketplace with structured flows for seekers and employers, improved discovery via AI-enhanced relevance, and a maintainable admin system. The integrated blog presents a unified brand across codebases.

This WordPress–powered blog mirrors the main portal’s look and feel via a fully custom theme. I extended style.css and functions.php to:

  • Import shared header/footer markup for seamless navigation.
  • Register custom post types, taxonomies, and template overrides matching Jobnet.ng styles.
  • Enqueue portal-aligned assets and override WP defaults for load performance.

Tech: WordPress, PHP, Custom Theme, REST/PHP Integration, SEO

  • Custom plugins: dynamic room filters, rate calendars, and shortcode-based amenities listings.
  • Performance & SEO: deferred non-critical scripts, optimized images, and rich metadata.
  • Owner-focused CMS: intuitive meta boxes and custom fields for updates without code.
