What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and professional growth in blockchain technology.

I am a graduate of the Polytechnic Department of Computer Engineering and Informatics at the University of Patras, with a strong focus on Blockchain Technologies. My journey has been enriched by extensive experience in EU Research projects, where I have honed my skills in software quality and project management.

Currently, I work as a Blockchain Developer at CERTH, where I contribute to various Horizon 2020 projects. My role involves developing smart contracts on Ethereum and Hyperledger Fabric, as well as designing architecture for IoT data management. I take pride in my ability to train consortium partners and present at international workshops, showcasing my commitment to knowledge sharing and innovation.

With a solid foundation in coding languages such as Golang, JavaScript, and Solidity, I am adept at utilizing modern technologies like Docker and NGINX. I am passionate about leveraging my technical expertise to drive impactful projects that contribute to sustainable development and technological advancement.
