During November 2025, Dusan Nosovic developed dynamic validator change management features for the Ethernal-Tech/apex-bridge repository, enabling bridge administrators to update validators through a new CLI command and an oracle contract that tracks change status. He enhanced reliability by refining API endpoints and improving parameter handling, all implemented in Go with a focus on backend and blockchain integration. In the Ethernal-Tech/blade-apex-bridge repository, Dusan introduced a configuration generation flag and expanded smart contract bindings, streamlining bridge setup and automation. His work demonstrated depth in API development, smart contract interaction, and CLI tooling, addressing operational risk and accelerating validator update workflows.
