Implementing and enhancing the JSON Rpc Relay (Js/Ts) to enable seamless EVM transactions submission to the network
Maintaining and evolve community tools like blockexplorer, verification and data gathering services, that hashgraph deploys for community servicing
Implementing examples, how-tos, and documentation that showcase web3 tool usage, and EIP and Hedera functionalities
Designing, developing, and maintaining server-side logic for back-end solutions with public APIs involving TypeScript, SQL, data ingestion, REST, GraphQL, and Web Sockets
Applying web3 knowledge of Solidity and life cycle of an EVM transaction
Writing efficient, reusable, and reliable code to optimize for maximum speed, scalability, and system efficiency
Exploring and unblocking web3 tool and dApp integration capabilities on Hedera, ensuring developers can continue to use their familiar tools when migrating to Hedera from other EVM chains
Spending 80% of your time designing, coding, and testing
