Marius Andronie is a former Romanian Army officer, a reserve captain engineer and graduate of the Military Technical Academy in Bucharest, who then spent more than twenty years typesetting books for academic publishers. Today he runs Devaland, a small software company in Romania that builds AI systems businesses can leave running. He writes practical, plain-language guides for real life: preparedness and self-reliance, managing money on one income, calmer days for seniors, healing after the loss of a pet, and putting AI to work safely. Each book is short, step by step, and made to be used.
