Full-stack BNPL platform for the South African consumer credit market.

Happy Pay is a buy-now-pay-later product designed for South African shoppers and merchants. AmberJack's engineering scope covered the full application stack: instalment calculation logic, credit decisioning flows, merchant API integration layer, and the consumer-facing checkout experience.

Building a BNPL platform requires navigating payment regulation, managing risk at the transaction level, and maintaining sub-second response times under concurrent checkout load. The architecture was designed to handle all three from the ground up.

Engineering contribution to one of Africa's leading online sports betting platforms.

Betway operates at the intersection of real-time data, financial transactions, and strict regulatory compliance. Contributing to a platform at this scale requires understanding not just the code but the operational reality: system behaviour under millions of concurrent bets, live odds feeds, and the compliance obligations of online gambling.

AmberJack's involvement focused on backend systems engineering — building features that could operate reliably under sustained high-throughput load and meet the platform's compliance requirements.

Enterprise physical access control and biometric identity management.

iPulse Systems provides biometric-driven access control to enterprise environments — from corporate campuses to secure facilities requiring multi-factor physical verification.

AmberJack contributed to the software layer that bridges hardware identity devices (fingerprint scanners, facial recognition units) with access management logic, audit trails, and integration into broader building management systems. Biometric systems have a uniquely low fault tolerance — a false negative means a locked door, a false positive means a breach. The engineering reflects that reality.

AmberJack's own AI-powered used-car search engine for the South African market.

DriveMind is the intelligence engine behind VroomVroom — a natural language search product that aggregates listings from multiple South African used-car marketplaces. Instead of category filters and dropdowns, users describe what they're looking for in plain language: "a white SUV under R300k with low mileage" — and the system surfaces the right results.

Built entirely in-house. In final pre-launch stage.

A self-sovereign identity prototype replacing the email-to-chemist prescription workflow.

The current South African prescription process relies on email — patient data transiting unencrypted between doctors, patients, and pharmacies. AmberJack's Healthcare SSI prototype replaces this with a decentralized identity-based system where the patient holds their own credential, and pharmacies verify without a central authority ever possessing the data.

Built as an open source prototype on GitHub. The triangle: Doctor → Patient → Chemist. Privacy by design.
