PROFILE

Brendon Tan

Brendon Tan developed and modernized core transaction processing and testing features for the okx/op-geth and related repositories over a two-month period. He introduced inner transaction tracking and EVM pre-execution support, enhancing observability and debugging by refactoring Go code and adding configurable flags. In okx/xlayer-erigon, he stabilized real-time test suites by refining block-number assertions and implementing retry logic. Brendon also reorganized end-to-end smoke tests, improved code hygiene, and updated contract definitions to strengthen test coverage and maintainability. His work demonstrated depth in Go and Solidity development, backend engineering, and test automation, resulting in more reliable and efficient blockchain operations.
