Over seven months, Iva Brajer engineered robust backend and blockchain features across the smartcontractkit/chainlink-evm and related repositories. She developed secure workflow management APIs, implemented deterministic address derivation using Go and Solidity, and enhanced smart contract reliability with pagination, access controls, and gas optimization. Her work included production deployment of Workflow Registry v2, rigorous test coverage, and dependency hygiene to ensure maintainability. By introducing features like off-chain allowlisting, batch admin controls, and CREATE2-style hashing, Iva addressed scalability, security, and auditability challenges. Her technical depth is evident in the careful refactoring, protocol alignment, and comprehensive validation throughout the codebase.
Month: 2026-01 — Focused on delivering a robust workflow address derivation feature for smartcontractkit/chainlink-common, with strong test coverage and collateral improvements to address generation reliability. The work enhances workflow creation by providing a deterministic, collision-resistant owner address using a CREATE2-style hashing approach, plus comprehensive validation.

Summary for 2025-08: Delivered security-focused enhancements to WorkflowRegistry in smartcontractkit/chainlink-evm with two key changes: a paginated getAllowlistedRequests view for non-expired allowlisted requests, enabling efficient retrieval; and a set of security/maintainability improvements including an upper bound on expiration, struct-based configuration, and refined error handling, event names, and gas snapshot values. These changes improve reliability, governance, and auditability of allowlisted requests, while enabling scalable querying for downstream users and systems.
