Bio
Oliver Sawyer
Miro is a talented Software Engineer with motivation, energy, and an outstanding attention to detail when problem-solving. As the lead Test Engineer for the Smart Metering Device Assurance project, he was responsible for the development and operational management of a powerful framework for the testing of Smart Metering devices - a demanding project involving many challenges, but Miro was always patient and disciplined. He coordinates well with project management and effectively collaborates with several stakeholders with a keeness on finding creative new ways to improve operational practices to benefit efficiency and project impact. I found Miro to be highly adaptive, confident, and an excellent listener who is always willing to share and appreciate everyone's ideas with an open mind. He is considered an expert within Critical Software for his knowledge in the Smart Metering and utilities industries. I'm proud to have worked with Miro during the project and recommend him for his excellent leadership skills. He's taught me so much, and helped me to grow my confidence.
