During nine months at Parity, Ndk developed and maintained migration testing and automation infrastructure for the paritytech/ahm-dryrun repository, focusing on blockchain runtime upgrades and cross-chain asset flows. He engineered end-to-end migration validation, automated network provisioning, and robust test orchestration using TypeScript, Rust, and Node.js. His work included building CI-integrated tooling for asset trading, treasury, and governance migrations, as well as enhancing logging, error handling, and developer workflows. By consolidating test frameworks and automating complex migration scenarios, Ndk improved reliability and reduced manual intervention, delivering scalable solutions that accelerated feedback cycles and increased confidence in multi-network blockchain migrations.

October 2025: paritytech/ahm-dryrun — Consolidated migration testing enhancements with cross-chain proxy test coverage, network detection, endpoint handling, and lifecycle timing tweaks to improve reliability of migration tests across networks. Implemented account translation for proxy tests and Kusama remote-endpoint support, plus decoupled tests from migration_done.json and refined zombie-bite termination logic to reduce flakiness. Fixed polkadot migration tests and network detection in TS tests, increasing determinism across multi-network migrations. Business value: higher confidence in migration readiness, reduced debugging time, and expanded cross-chain coverage across networks.
