I build secure Solidity, DeFi, and Cosmos/EVM blockchain systems from smart contracts to production Layer-1 networks.

India

Message

I've built production blockchain systems at MTransform and EspSofttech, spanning Solidity smart contracts, DeFi launchpads, DEXs, cross-chain swaps, and EVM-compatible Layer-1 networks. My work includes signature-bound Permit2 execution, Uniswap V3 liquidity automation, and secure multi-wallet infrastructure across EVM and TRON ecosystems.

I led INFIMultichain LaunchPad & CDEX from concept to production and launched Cosmos/EVM chains through mainnet, achieving 99.9% uptime, sub-5-second finality, and 25–40% lower transaction costs. I also completed a ~$1M+ TVL staking migration with zero downtime or fund loss and focus closely on pre-deployment security reviews, gas optimization, and resilient upgradeable contract design.
