About Selah Tech Solutions

Nduvho Edward Ramashia

Embedded Systems Engineer focused on production-deployed facility monitoring systems.

Nduvho Edward Ramashia is an Electrical & Information Engineering student at Wits University, specialising in embedded systems design and PCB development.

In 2023–2024, he designed and deployed a production pressure monitoring system at iMining (Pty) Ltd - a real-world project combining 4-20mA sensor interfacing, STM32 firmware development, custom PCB design (Autodesk Eagle), and a real-time browser-based dashboard. The system ran at 99.2% uptime and detected anomalies that manual checks would have missed.

Selah Tech Solutions is built on a direct premise: factory and workshop operations need facility monitoring systems that are reliable, measurable, and backed by engineering competence. No vaporware. No consulting fluff. Deployed systems.

Our Approach

Engineering Competence, Measurable Results

Factories and workshops need systems that work in harsh conditions, report accurately, and keep running. That is the only standard we build to.

Engineer-Led

Every system is designed and built by Nduvho - a Wits Electrical & Information Engineering student specialising in embedded systems and PCB design. No account managers, no outsourcing.

Production Systems, Not Prototypes

We deploy working hardware into real industrial environments. The iMining pressure monitoring system has been running continuously since 2024 - 99.2% uptime, zero false positives.

Full-Stack Hardware & Software

From 4-20mA sensor selection and custom PCB layout (Eagle) to STM32/ESP32 firmware (C/C++) and a real-time web dashboard - we own the entire stack.

Measurable Outcomes

We track what matters to facility managers: detection latency, alert accuracy, uptime, and downtime prevented. If we cannot measure it, we do not claim it.
