Live projects
Founder reference builds
In development
POS NAMI — sales & inventory platform
A live product we built and run ourselves: point-of-sale, inventory, customers and day-to-day operations for retail businesses.
Mbuni Luxury Lodge — hospitality website
A guest-facing website for a real lodge property, designed to showcase rooms and experiences and make it easy for guests to get in touch.
Secure — security-focused platform
A security-focused digital platform we designed and maintain, built around access control and dependable day-to-day system operations.
Multi-tenant ERP — accounting through to BI
Our founder engineered a multi-tenant ERP of this class in production: accounting, sales, procurement, inventory, CRM, fixed assets, BI and administration inside one role-based system. It is the exact architecture we deploy for clients who need it.
ISP operations & support back-office
Our founder built a full ISP back-office: subscriber management, field technician dispatch, fault tickets, billing records and cable inventory. We deploy the same foundation for internet providers and network operators.
Authorised security testing & audits
We assess systems you own, or are contracted to test: vulnerability scanning, web and network penetration testing, hardening, and a written report with prioritised fixes. Every engagement is scoped and authorised in writing before any testing begins.
Hotel management platform
A single platform covering the whole property: reservations and room allocation, guest profiles, housekeeping, billing, on-site point of sale and management reporting — replacing the notebooks and spreadsheets most properties still run on.
IPTV streaming web app
A progressive web app for live IPTV: channel lineups, adaptive streaming, an in-browser player and mobile install. Deployed on Ubuntu with Nginx and Docker, so it scales with a growing subscriber base without rebuilds.
TapServe — QR ordering platform
Guests scan a QR code, order from the menu and pay; the kitchen sees every order the moment it lands, with table status and sales running alongside. Built for busy counters where speed and clarity matter.
JayWorld — offline desktop app
An offline invoicing and inventory desktop app for a client who cannot depend on connectivity: multi-role access, an audit log, PDF export and local SQLite storage. It keeps working when the network does not.
Chart analysis & trading assistant
A chart-based assistant that reads market data, runs technical analysis and returns signals, backed by a Python service. Started as a final-year project and continued since, with backtesting and risk management designed in from the beginning.
Interfaces shown are illustrative concepts created to represent this type of system.
