Rockstar🎓
Top SchoolRigel Rozanski is a software engineer with a decade of experience building robust back-end systems and contributing to high-profile open-source blockchain projects like Tendermint and the Cosmos SDK. With a foundation in environmental engineering from the University of Guelph, Rigel bridges domain thinking in hydrology and GIS with modern stacks in cryptography, auto-trading, AR, ML, and BCI processing. Their commits show a focus on core protocol logic, RPC/networking, and cross-chain security updates—demonstrating comfort working deep in consensus, IBC, and staking/distribution mechanics. Equally at home producing audio and hosting community events, Rigel brings a multidisciplinary creativity that surfaces in experimental audio feed processing and real-world tinkering (backyard veggies and renovated shed naps included).

cosmos/interchain-security
Jan 2022 - May 2022
Interchain Security is an open sourced IBC application which allows cosmos blockchains to lease their proof-of-stake security to one another.
Role in this project:Back-end Developer
Back-end DeveloperContributions:43 reviews, 43 commits, 5 PRs in 4 months
Contributions summary:Rigel's commits primarily involve updating the project to use IBC-go v3. They refactor existing code, specifically within the x/ccv directory, to accommodate the changes in the IBC-go library. These updates involve modifying module configurations, keeper interfaces, and test files to ensure compatibility with the new IBC-go version. Additionally, the user works on distribution logic including implementation of consumer redistribution fractions, and sending tokens to a provider chain, which is essential for Interchain Security functionality.
