Over a two-month period, this developer enhanced cross-chain compatibility and asset management in blockchain projects. For skip-mev/skip-go, they refactored the Public Key Parser to support multiple public key types for Ethereum and Cosmos EVM accounts, improving multi-chain integration and future extensibility using TypeScript and EVM compatibility expertise. In cosmostation/chainlist, they delivered asset metadata updates for XPLA, refined CoinGecko integration, and aligned Axelar USD Coin representation, while also rolling back configuration changes to restore stability. Their work demonstrated strong skills in API integration, JSON, and configuration management, with a focus on maintainability, data accuracy, and robust blockchain development practices.

In May 2026, I delivered targeted asset data improvements for cross-chain assets in cosmostation/chainlist and completed essential configuration rollbacks to restore stability. Key work included: (1) Asset metadata and integration updates for XPLA with new token/NFT entries, refined CoinGecko metadata, and updated Axelar USD Coin representation, supported by commits e490cc46ace82f1fb61bc175fd4a338d4fa9d772; 92578ea9d70d407235fac2b67f20fb7debdf96ef; 8c06fffcc2dbf0ee19c189f3cb9ac0ff42452cff. (2) Configuration compatibility rollbacks and cleanup to restore compatibility: rollback pubkey type, removal of cw721 references, and removal of the is_feemarket flag, with commits 38d09cae6c6a236da46a64e8d450720da9c035e9; de915abb64000315a2785beba4632f819759b50b; 641258dbe876fb8815e36f31686a320b10a80759. (3) Quality and reliability improvements through CoinGecko appid fix and continued normalization of asset data, contributing to better third-party data accuracy and reduced maintenance risk.

December 2025 highlights for skip-mev/skip-go: Delivered a targeted enhancement to the Public Key Parser to support multiple public key types for Ethereum and Cosmos EVM accounts, improving cross-chain compatibility and functionality. Implemented as a refactor focused on flexibility and future extension, anchored by a dedicated commit to adjust the parser's handling across account types. This work reduces integration friction for multi-chain deployments and strengthens the project’s value proposition for developers building on Cosmos EVM and Ethereum ecosystems.
