What we build

Software for the gap between "off-the-shelf" and "we can't afford a dev team."

Most businesses either overpay for generic software that half-fits, or go without. We build the specific thing you actually need.

Programs

Custom business software

Invoicing, job tracking, dashboards, internal tools — built on ASP.NET Core and Razor around how your business actually runs, not a template you have to adapt to.

Mobile

Android apps

Native Kotlin apps for field teams, customers or staff — camera, GPS, barcode scanning and offline sync built in where you need them.

Web

Web apps & dashboards

Fast, interactive interfaces built with React and Vite — for internal tools, client-facing dashboards, or anything that needs to live in a browser.

Infrastructure

Self-hosted platforms

Systems you run on your own infrastructure and own outright — no monthly per-seat fees to a foreign SaaS vendor.

Proof, not promises

Software we've designed, built and put into use.

Real systems, running in production — not mockups.

Erongo IT Job Tracker

Field-service management system

An Android app for field technicians paired with a self-hosted sync API and admin portal. Photo capture, barcode scanning, GPS-tagged jobs and offline-first sync, built from a mockup through to a working system.

Kotlin / Jetpack Compose ASP.NET Core PostgreSQL Offline sync

Stock & Invoice Management System

Multi-tenant SaaS invoicing & ERP

A dashboard-driven stock and invoicing platform serving multiple businesses from one codebase — built for organizations that outgrew spreadsheets but don't want to pay per-seat for a bloated ERP suite.

ASP.NET Core MVC PostgreSQL Multi-tenant

RayDesk

Remote administration platform

A custom-built remote support and device-management platform, built in-house instead of paying ongoing licensing for third-party RMM software.

Client Backup System

Self-hosted backup platform

A CrashPlan-style backup system for clients — continuous, automated backups to infrastructure you control, without paying per-seat for a foreign SaaS subscription.

Self-hosted Automated backups In development

Personal Media Platform

All-in-one self-hosted media hub

A private platform where a client logs in to access their movies, shows, books, music and audiobooks, a security vault, and a torrent downloading system — all under one account, on infrastructure they own.

PC Specification Harvester

IT auditing software

Auditing software that scans a PC, gathers its hardware and system specifications, and sends them automatically to a central database. Every machine's details are stored in one place and can be retrieved through a web portal.

How we build

Four steps. No black box.

01

Spec

A plain-language conversation about what the software actually needs to do — no jargon, no guesswork.

02

Build

We design, write and test the software using the right tool for the job — React, Razor, Kotlin, whatever the project calls for.

03

Ship

Deployed on infrastructure you control. Your software, your data, no vendor lock-in.

04

Support

We stay on to fix, extend and maintain what we built — the same person who wrote it answers the phone.
