# Salitronic

> Salitronic is an independent electronic design consultancy run by George Saliba, an electronics engineer with 20+ years of experience based in Malta. It delivers end-to-end hardware product development handled directly by one senior engineer, with no subcontracting or project managers: specification capture, schematic design, PCB layout (including HDI, flex, rigid-flex, RF, high-speed, and compute-module carrier boards), firmware (bare-metal and RTOS), analog and power electronics, motor control, and pre-compliance EMC testing. Recurring specialties include BLE and cellular IoT (Nordic nRF52/nRF53 and nRF91), low-power battery-powered sensors and data loggers, precision analog and mixed-signal front ends, and independent PCB design review and DFM audit before fabrication. Clients range from early-stage hardware startups to established companies across 15+ countries, and they own all design files, source code, and documentation.
