Want to work with an experienced Blockchain developer who can bring your smart contract, decentralized application (dApp) vision to life? Are you looking for a Solidity or Rust developer to develop "Gas-Optimized" smart contracts? Whether you're looking to create ERC20 or SPL tokens, ERC721, ERC1155, or NFTs with custom features, concerned about vulnerabilities and exploits in your high-value contracts, need to write tests for contracts, or need a script to interact with leading DEX protocols—I've got you covered.

🖐 Some of my previous clients' quotes about me:
✔️ "...Excellent technical skills and consistently good communication... Completed the project in a timely fashion, exceeding our original deadline."
✔️ "His work was phenomenal...made sure I understood every step along the way...
✔️ "..took this project on as if it was his own... Great professional skills, always there to answer questions and suggest the best solutions."
✔️ "...Every facet of his work was impressive. WOW!"
✔️ "... goes above and beyond. Md's professionalism and expertise in blockchain are unmatched.."
✔️ "... communication is excellent, delivery is fast, and his knowledge of smart contracts is impressive."

With expertise in EVM-compatible chains (like Ethereum, BSC) and Solana, I specialize in delivering high-performance, gas-optimized smart contracts and dApps tailored to your specific requirements. I help my clients build secure and highly resilient smart contracts, minimizing vulnerabilities and ensuring your code is fortified against exploits.

I might be the perfect fit if you're thinking of any of these:
✅ "I need the BEST developer who's as passionate about my success as his own."
✅ "I want someone who will walk me through every step of smart contract interaction."
✅ "Gas fees are too high! My smart contract needs to be lightning-fast and cost-efficient."
✅ "I know blockchain, but I need a professional to make my smart contracts 100% secure."
✅ "I’m not an Ethereum or Solana expert, and I don’t have time to mess around with dApps."
✅ "Our last dApp was a disaster—I can’t afford to let that happen again."
✅ "I need an EVM-compatible blockchain or Solana expert to cover all my bases for cross-chain or multi-chain applications."

Working with me, you will:
💎 Gain access to a developer skilled in Python, JavaScript, TypeScript, Rust, Solidity, Brownie, Hardhat, NextJS, Foundry, and Anchor.
💎Eliminate vulnerabilities and reduce gas fees during both deployment and interactions.
💎 Maximize your DApp's security with continuous follow-ups for improvements.
💎 Save time and resources—you won’t need to hire separate back-end, front-end, Rust, or Solidity developers because I handle it all as a full-stack developer.
💎 Receive custom scripts to swap, add, or remove liquidity, lend, deposit, borrow, withdraw, and interact across top dApp protocols.
💎 Optimize for multi-chain functionality—Whether you need to bridge Ethereum, BSC, or Solana, I can create solutions that integrate seamlessly across multiple networks.

BSC Token Deployment Support Sumon was exceptional from start to finish. He guided me through a complex BSC mainnet deployment including contract deployment, token distribution, LP locking through UNCX Network, multisig governance setup, and trading activation. He came prepared, ran a full testnet simulation the night before launch, and walked me through every step with patience and clarity. Every transaction was verified on BSCScan before moving forward. Nothing was rushed, nothing was skipped. If you need a developer who is technically sharp, reliable, and genuinely invested in getting it right, Sumon is your person. I could not recommend him more highly and will absolutely work with him again.

30 minute consultation Sumon is very professional and helpful in the consultation. I look forward to keep working with him.
