About this Gig

Specialized Contract Services:

  • Custom ERC-20 Tokens: Deflationary logic, reflection/tax systems, and anti-whale mechanisms.
  • NFT Collections (ERC-721/1155): Randomized minting, reveal logic, and whitelist/allowlist management.
  • Staking & Farming: Complex reward distribution logic and time-locking.
  • Governance (DAO): Implementation of voting and proposal systems.
  • L2 Optimization: Specialized deployment for Base and Polygon to minimize gas costs.


My Engineering Process:

  1. Requirement Analysis: Understanding your specific tokenomics.
  2. Development: Clean Solidity code with NatSpec documentation.
  3. Testing: Comprehensive test suites using Hardhat or Foundry.
  4. Deployment: Assisting with mainnet and verification on Etherscan/Basescan.


Protect your project and your investors with high-integrity, audited Smart Contracts.

In the world of DeFi and NFTs, a single bug can be fatal.


I specialize in developing secure, gas-optimized Solidity smart contracts for Ethereum, Base, Polygon, and all EVM-compatible chains. I dont just write code; I implement industry-standard security patterns using OpenZeppelin and conduct rigorous Unit Testing to ensure your contract is bulletproof before deployment
