Veronika A.

I'm a software engineer specialising in blockchain and backend development with 4 years of professional experience. I have a degree in Computer Science & Applied Mathematics, and I combine both applied research, and industry-level experience in blockchain development. I have been working in a research team developing a new protocol -- Byzantine Optimistic Reliable Broadcast, resulting in a successful publication of our paper on the International conference of OPODIS 2024. As well as that, I was working in three startups in the blockchain space, where I was a core developer of a Cosmos SDK based blockchain and of a consensus workflow execution layer (built on the pBFT-like protocol). I was working on development of Solidity smart contracts and on integration of the Symbiotic and EigenLayer restaking protocols. I was interning at Google twice while studying at the university (totalling to 7 months of full-time work at the Google office), and I have extensive experience with backend development in Java, Kotlin and Golang. I deliver high quality code with a focus on readability, efficiency, extensibility and good test coverage.
