Hi, I am Paraskevas K. Leivadaros
CloudOps Engineer
I'm a Cloud Operations Engineer at DigitalOcean 🦈 with multi-cloud certifications ☁️, currently pursuing a Master's 🎓 in Data Science 📊🧑🔬 at the University of Amsterdam!
I ensure the smooth operation of our cloud infrastructure by monitoring and promptly responding to all cloud health issues that could impact customer experiences, both internal and external. Reporting to the Manager of Cloud Operations, I collaborate with teams across the organization to research and troubleshoot issues, from single droplets to cloud-wide disturbances. My day-to-day tasks include ensuring maximum uptime for DigitalOcean’s global infrastructure, automating processes, developing tools to enhance operational efficiency, and coordinating with various teams to address operational challenges and improve the platform with minimal user impact.
I specialized in the implementation and technical support of telecommunication services for both Greek and international telecom organizations. These systems were critical for serving millions of users. My role involved developing and maintaining applications for corporate mobile telephony clients, providing me with a comprehensive understanding of the complexities and needs of large-scale telecommunication networks. I was involved in several ServiceWeaver™ microservices such as Bulk-SMS, Balance Inquiry, Internet Abroad, and Prepaid Orchestrator. In these projects, I was integral to every phase of their development and rollout.
I was responsible for performing troubleshooting of computer systems, hardware, and software. This involved identifying issues and providing timely solutions to ensure that systems were running optimally. I also gained expertise in resolving network problems, which included giving users clear instructions on how to perform tasks related to network maintenance and troubleshooting.
I gained extensive experience in SEO techniques, social media management, and creative thinking. I was proficient in web management using WordPress and created engaging blog content. My experience with Google Analytics and Search Console honed my data analysis and problem-solving skills. Additionally, I managed client reviews and online travel agencies' systems, developing my communication and customer service abilities. Overall, I gained valuable skills in digital marketing and web management, as well as data analysis and client management that I can apply to future roles.
At the Computer Science Laboratories of the Athens University of Economics and Business, I was responsible for both systems monitoring and direct communication with end users

I am running protein dynamics simulations on a Linux server to aid in developing therapeutics for various diseases. Folding@home is a distributed computing project that simulates protein folding and protein-protein interactions to help researchers develop new treatments for diseases like Alzheimer's, cancer, COVID-19, and autoimmune diseases. The project provides a better understanding of disease mechanisms, which could lead to the development of more effective treatments.
I am helping advance cutting-edge scientific research by participating in volunteer computing projects. These projects utilize the idle processing power of personal computers to perform large-scale scientific simulations and data analysis. The specific projects I am involved in focus on a range of scientific disciplines, including climate prediction, astrophysics, molecular biology, cryptography, and mathematics.
Donating server resources to science projects like Help Stop TB, Africa Rainfall Project, Mapping Cancer Markers, Smash Childhood Cancer, OpenPandemics - COVID-19 and Microbiome Immunity Project!
Hey there, I am glad you're interested in my projects! If you have any questions or just want to chat, feel free to reach out. I am always excited to hear about new opportunities, let's connect and have a friendly conversation!
