Senior🎓
Top SchoolIjonas Kisselbach is a blockchain architect and seasoned technical leader with 25+ years of software experience and 17 years in engineering leadership, now based in Glasgow. He designs end-to-end blockchain systems spanning Bitcoin-native protocols, EVM smart contracts, tokenomics and cross-chain infrastructure, and has led audits and security remediations with firms like Halborn. As CEO of a Chainlink-focused oracle company and architect for yield-bearing Bitcoin protocols, he combines production uptime engineering (99.99% RPC/node availability) with deep protocol-level expertise in P2TR, UTXO management and rebasing token design. He’s built teams and delivery processes that turned failing deployments into reliable daily releases and raised test coverage from 15% to 70% at scale. Currently he’s pioneering human+AI engineering workflows — integrating Claude Code agents into CI/CD to automate blockchain audits and cut external audit costs by ~30%. A longtime open-source contributor (including practical fixes to the Fog Ruby cloud library), he blends hands-on coding with pragmatic product and security stewardship.

Contributions summary:Ijonas primarily focused on fixing bugs related to the `dns.zones()` and `zone.records()` methods within the Fog library, specifically within the context of the DNSimple provider. These changes involved correcting the return of empty objects and ensuring proper data population. The user also updated the `zone.get()` method to return fully-populated record objects and made revisions to the `record.save()` method to handle both new and existing records correctly.
