Case Study 01 · Founder project

SaleStation POS

A cloud-based point-of-sale and business management platform for retailers in South Africa, Botswana, Lesotho and Namibia.

Role

Founder & lead developer

Year

2026

Stack

PHP · MySQL · PWA · Paystack

Status

Live

The problem

Small and mid-sized retailers across southern Africa often run on paper slips, spreadsheets or heavy desktop software. Owners lack live visibility into sales and stock, items get oversold, and it is hard to tell which cashier did what. Tools built for other markets also tend to handle regional currencies and local payment rails poorly.

The solution

One distraction-free platform where owners register in minutes, add items and staff, and start selling straight away, with no software to install.

• Role-based workspaces for super-admin, admin and cashier
• Stock-aware checkout: warnings at 5 units, automatic lock-out at zero
• Multi-store support with isolated per-branch inventory and shared items
• Itemised receipts with unique transaction IDs, flat or percentage discounts and automatic change
• Paystack subscription billing in ZAR with a 2-day grace period, audit logs and Excel/CSV exports
• Display currencies: ZAR, BWP, LSL and NAD

Case Study 02 · Client project

Dr Jacob Segale

A professional website, publishing hub and online shop for a public health researcher and author with 20+ years of experience across Africa.

Role

Design & full-stack development

Client

Dr Jacob Segale

Stack

REST API · JWT · Paystack · CMS

Status

Live

The problem

Dr Segale's biography, books, journal articles and writing needed one credible online home, with a simple way for readers to buy publications and for him to keep content current without needing a developer for every update.

The solution

A full-stack portal that pairs a polished public site with a private admin suite and secure checkout.

• Content management for books, articles and blog posts with rich-text editing and draft-to-published states
• Paystack checkout with a webhook listener that confirms payments server-side
• Session-based shopping cart and secure download keys for purchased titles
• JWT-secured admin dashboard with an activity log
• Books and articles load dynamically from the API into a responsive public site

Key Achievements

Every client engagement follows the same disciplined path - turning a rough idea into a clear brief, then into a working, deployed product, with no surprises along the way.

1. 01

   Discover & Listen

   Start with a conversation to understand the client's goals, workflows, and pain points - the "what" and the "why" behind the request, not just the surface ask.

2. 02

   Scope & Specify

   Break the idea down into concrete features, user flows, and a prioritised list of specifics - pages, roles, data, integrations - so both sides agree exactly what is being built before code is written.

3. 03

   Design & Plan

   Map the structure, data model, and interface around that spec, and agree on a realistic timeline and milestones with the client before development begins.

4. 04

   Build & Review

   Develop in incremental stages, sharing progress regularly so the client can review, test, and request changes early rather than only at the end.

5. 05

   Launch & Support

   Deploy the finished product to production, hand over a clear understanding of how it works, and stay on for fixes, refinements, and future growth.
