Blockchain developer focused on designing and implementing secure and gas-efficient smart contracts in the Ethereum ecosystem. Strong understanding of DeFi primitives including AMMs, liquidity pools, lending mechanisms, and token standards (ERC20, ERC721). Experience working with upgradeable contract patterns and contract architecture design. Background in backend development with Python and experience building APIs and integrating on-chain and off-chain systems. Currently expanding into Java and Spring Boot for building structured backend services. Comfortable working across the full Web3 stack including smart contracts, backend services, and Web3 integrations.
Implemented core AMM mechanics following the constant product formula (x*y=k), including liquidity provisioning, token swaps, and reserve management. Designed smart contract logic for liquidity pools, pricing, and fee handling with focus on correctness and determinism. Included unit testing and validation of swap logic and edge cases.
Designed a gas-efficient token distribution system using Merkle Tree verification for eligibility. Implemented secure claim mechanism with one-time usage protection and immutable root validation. Focused on minimizing gas costs and preventing double-claim vulnerabilities.
Developed an upgradeable smart contract system using the UUPS proxy pattern. Implemented role-based access control for upgrade authorization and secure contract evolution. Ensured storage layout compatibility and integrated reentrancy protection mechanisms.
Built a backend automation system for processing B2B workflows with role-based access control and structured command handling. Implemented scalable architecture for handling user input and automated actions.
