Dreamware Tech

Client build • PHP + MySQL + CSS + JS + Automations + API Integrations

An online e-commerce store selling computer components, Dreamware Tech is one of the top-rated online computing hardware stores in South Africa — with multiple thousands of users and an astounding 100% five-star rating across Google, Facebook, and Hellopeter.

Run by husband and wife Brent and Jess Raftopoulus out of Durban, Dreamware is consistently praised for its excellent delivery turnaround times and after-sales service. As cited by MyBroadband: "the best-rated online computing hardware store in South Africa." Includes a custom-built CMS for managing product catalogues, orders, inventory, and site-wide analytics.

SockClub

Client build • PHP (Frameworkless) + CSS + JS + Tailwind + API Integrations

A monthly subscription service where customers sign up and receive curated socks delivered to their door every month. The platform integrates multiple payment gateways and a delivery system for seamless end-to-end operations.

Once a subscription is triggered, the entire workflow runs automatically — an order is created and placed, and delivery services are notified to pick up and ship directly to the client. No manual steps, no friction. Backed by a custom-built CMS for managing subscriptions, order processing, delivery tracking, and customer data.

CHERISH Ranking Platform

Client build • PHP + CodeIgniter + MySQL + CSS + JS + AI Integrations

An internal tool built for John Bielinski, distributed to his clients as a weekly self-ranking platform based on the CHERISH system — Career, Health, Ego/Emotions, Relationships, Integrity, Spiritual, and Happiness.

Users compare where they were versus where they are now, tracking their scores over time. The platform applies proprietary internal formulas to deliver meaningful insights back to the user, along with automated notifications prompting them when it's time to rank themselves. A custom-built CMS powers the backend, enabling management of user accounts, ranking data, scoring configuration, and notification schedules.

CV Hub

Client build • PHP + Angular + CSS + JS + Chart.js + AI Integrations

Introducing CVHub — a web-based career support platform built to simplify and improve the job search experience. CVHub helps job seekers create impactful CVs and cover letters and connects them with employers in a streamlined and privacy-focused environment.

Key capabilities include:

  • A custom CV builder that lets users quickly produce professional-quality resumes tailored to their goals.
  • Direct communication tools that enable secure, flexible messaging between candidates and employers without intermediaries.
  • A platform design that prohibits recruitment agencies, helping reduce noise and protect job seekers.
  • Built-in confidentiality and anonymity controls, giving users full control over their personal information and who sees it.
  • A growing community of users, with thousands of job seekers already using CVHub to advance their careers.

CVHub's approach makes it easier for candidates to present themselves professionally and for employers to discover talent efficiently — all in one place. A custom-built CMS underpins the platform, giving administrators control over user management, employer accounts, job listings, and platform-wide statistics.

PAGE RADAR-BRAND PROTECTION WEB APP

Client build • PHP + CodeIgniter + CSS + JS + APIs

A custom web-based platform built for Globaleyez that automates the monitoring of product listings across online marketplaces. PageRadar verifies whether items are still available by evaluating HTTP status responses, inspecting page content for removal indicators, and connecting directly with marketplace APIs where supported.

RabbitMQ handles message queuing for high-volume URL processing, while intelligently spaced scheduling reduces bot detection risk. Automated daily reports provide clear visibility into scanning outcomes. A custom-built CMS ties it all together — managing monitored URLs, scan results, scheduling rules, and reporting dashboards.

There are plenty more back-end services and applications behind the scenes — but unfortunately, nobody throws a parade for a well-optimised database query. Feel free to reach out and ask about the ones that don't get a screenshot.
