Custom web applications, security audits, data science, and DevOps infrastructure for SADC organisations. Every project ships with a test suite, CI/CD pipeline, and deployment documentation.
End-to-end engineering — REST APIs, React UIs, ML models, Docker infrastructure, CI/CD pipelines, and security reviews. One engineer who owns the whole stack.
PHP 8 · React · FastAPI with MySQL or PostgreSQL. REST APIs, RBAC, JWT auth, WebSockets. From simple business tools to complex multi-role platforms.
Structural code audits for PHP, Python, and Node.js. OWASP Top 10, auth flows, secrets hygiene, injection surfaces, session management. Written report + reproducible fixes.
ARIMA · SARIMA · Prophet forecasting. CNN image classifiers (MobileNetV2). Monte Carlo simulations. Plotly Dash dashboards. FastAPI model serving. Calibrated on real datasets.
Docker Compose · Nginx reverse proxy · GitHub Actions CI/CD · Prometheus/Grafana monitoring. Blue-green deployments. Production-ready infrastructure from day one.
POS, booking systems, staff portals, inventory management. Built for businesses in Eswatini, South Africa, Botswana, and the wider SADC region.
Monthly support for live systems. Bug fixes, small feature additions, dependency updates, priority response. Flat rate, no surprises.
A repeatable process that produces predictable outcomes. You know the price, timeline, and deliverables before any work begins.
15 minutes, free. I understand the problem, technical constraints, and deadline. You get a realistic sense of what's buildable and at what cost.
Written proposal with exact scope, deliverables, and price in ZAR. No hourly ambiguity. No "we'll see how it goes." Valid 14 days.
Test-driven development, GitHub Actions from day one, daily commit visibility. You can see progress in the repository as it happens.
Full source code, docs, CI pipeline, deployment runbook. 30-day bug-fix warranty. You own everything — no lock-in.
Five active repositories. Real deployments with live users, verified test suites, and documented security postures.
Command-and-control platform for drone fleet management. 27,900 lines, 16 MVC controllers, RBAC with 4 roles, TOTP 2FA, Merkle audit log, WebSocket telemetry. 9/9 findings resolved.
