PROFILE
Leo Jeong
Worked on the Consensys/linea-monorepo, delivering upgrades and stability improvements to the prover and Ethereum smart contract infrastructure. Focused on backend development and system integration, this work included multi-network protocol upgrades, dependency and submodule management, and enhancements to cryptographic circuits using Go, Solidity, and Node.js. Addressed build reliability by refining CI/CD pipelines and resolving issues with compiler downloads and submodule drift. Implemented new transaction type support and optimized performance for large execution circuits, ensuring compatibility with evolving Ethereum standards. Emphasized modular design, robust configuration management, and continuous integration to support production readiness and reduce operational risk across deployments.

Mar 1, 2026Month 2026-03: Stabilized CI for Consensys/linea-monorepo by eliminating Hardhat compiler download failures in CI, mitigating API rate limits, and aligning dependencies for long-term stability. Implemented caching of Hardhat binaries, pre-downloads of solc, and pre-compilation steps to ensure deterministic contract coverage and faster feedback loops. Demonstrated strong CI/CD discipline and Solidity tooling proficiency, delivering measurable business value through more reliable builds, faster iteration, and reduced flaky tests.
