Fintech
Credit and payment systems under real market constraints.
BNPL logic, merchant integration, checkout flows, and transaction paths built for South African risk, regulation, and latency realities.

Software for domains where details carry weight.
AmberJack is a senior South African software studio. We build the systems behind fintech, gaming, biometrics, automotive AI, privacy-by-design healthcare prototypes, and the bespoke work that does not fit a template.
Tell us the idea, the domain, and the constraints. We handle the architecture, engineering, and craft.
Capability map
Different domains. The same demand for precision.
AmberJack’s work is not tied to one vertical. The common thread is software where domain rules, data quality, and operating constraints shape the engineering.
Gaming
High-concurrency platforms where timing and trust matter.
Engineering contribution to real-time online gaming environments: load, compliance obligations, operational safety, and fast-moving product surfaces.
Biometrics
Identity and access control with low tolerance for ambiguity.
Fingerprint, facial recognition, enterprise access workflows, and physical-security integrations where false positives and false negatives both have consequences.
Healthcare prototype / SSI
Privacy-by-design workflows for sensitive data experiments.
Open-source prototype work around self-sovereign identity and digital prescription flows; designed around privacy constraints, not claimed as clinical production software.
Automotive AI
Search intelligence for messy marketplace data.
DriveMind powers VroomVroom: multi-source vehicle aggregation, natural-language intent parsing, normalization, and search relevance for South African used cars. Launching soon.
Bespoke systems
The uncommon software between your domain and your users.
APIs, dashboards, product workflows, internal tools, integrations, and rebuilds where the right architecture matters more than a fashionable stack.
Selected work / proof
Shipped work, and product-stage honesty.
Production language is reserved for real client work. DriveMind / VroomVroom is launching soon; Healthcare SSI remains an open-source prototype.

Start with what you are building, what must not fail, and what constraints are already known.
Start a conversationHow we work
Architecture before code. Domain before decoration.
AmberJack is small by design. You work with senior engineering judgement early, when decisions are cheapest and most consequential.
Read the domain first
We map users, constraints, edge cases, data shape, regulation, and failure modes before choosing architecture.
Design the operating system
Information architecture, data models, API boundaries, and interface flows come before production code.
Build with rigour
Strict TypeScript, static-first pages where possible, tested integrations, observable services, and code the next engineer can reason about.
Ship, explain, sustain
Deployment, documentation, handover, and maintenance posture are part of the work, not a cleanup phase after launch.
Gqeberha / South Africa
A grounded studio with senior hands on the work.
AmberJack was founded by Grant Vine in 2017 in Port Elizabeth (Gqeberha). The studio’s track record spans payment infrastructure, gaming platforms, biometric access control, an automotive AI product, and privacy-by-design healthcare prototype work.
It is not an agency built around handoff theatre. It is a software studio for clients who care how the system is reasoned about, built, and sustained.
