Role	Required	Description
Smart Contract Developer		Understands the EVM gas model: SLOAD/SSTORE costs, calldata vs memory, opcode pricing. Applies basic optimizations: storage packing, immutable variables, unchecked arithmetic for safe operations.

Role	Required	Description
Smart Contract Developer		Applies advanced gas optimizations: calldata instead of memory, custom errors instead of require strings, bit manipulation. Profiles gas via forge test --gas-report and optimizes hot paths.

Role	Required	Description
Smart Contract Developer		Designs gas-optimal architectures: inline assembly for critical paths, SSTORE2 for cheap data storage, EIP-1153 transient storage. Optimizes deployment and runtime costs for DeFi protocols.

Role	Required	Description
Smart Contract Developer		Defines gas optimization standards for the organization. Establishes gas budget framework and regression detection. Coordinates optimization initiatives for production protocols.

Role	Required	Description
Smart Contract Developer		Defines enterprise gas optimization strategy. Researches EVM gas schedule evolution and its impact on existing contracts. Publishes gas optimization research and novel techniques.
