Project details

Looking for a highly skilled Solidity developer to design, develop and deploy optimized, efficient and well-tested smart contracts for your project?

Look no further! As a Solidity developer, I understand that creating a functional, unhackable smart contract can be a time-consuming and challenging task, especially if you have other projects to manage.

With my service, you can rest assured that the process will be handled efficiently and effectively. I have extensive experience designing and developing smart contracts with EVM compatibility, ensuring that they are unhackable and secure.

I have also helped clients optimize and reduce gas fees by up to 20% by implementing efficient coding strategies.

working with me, you will stop worrying about:
*GAS Optimization
*Security & exploits
*Narrowing Idea
*setup and installation process
*smart contract library
*web3 framework
*walk through the code
*Blockchain Platform

If you are ready to take the next step in your project, select your desired package and simply click the green "Continue" button. You can also send me a message to discuss your project in more detail. Don't let smart contract development hold you back - let me handle it

Smart Contract Development This feedback is long overdue.

Md created two smart contracts for me and his work was phenomenal. Before we got started, he researched the solution to ensure that it was even possible. After his research, there was no pressure to move forward. He explained all the limitations, instead of simply saying that everything is possible. That gesture alone let me know that Md was truly focused on devising a solution.

Along the way, we made changes and Md was sure to make sure I understood. He made explainer videos and followed up with me as well. While I am still in the process of deploying this project, I am happy to say that I look forward to working with Md again soon. I have been lucky to work with great developers here, like Md. Thanks Md!

Want to work with an experienced EVM-compatible Blockchain developer? looking for a Solidity developer to develop "Gas-Optimized" smart contracts or Dapps? Want to create your own ERC20 token, ERC721, and ERC1155 NFT with additional features? Worrying about your thousands of dollars smart contract getting hacked or do you want to prevent vulnerabilities and exploits? Or are you looking for a program/script to interact with the giant DEX protocols?

I help my client with unhackable EVM-compatible solidity smart contracts which have no chance of being vulnerable.

I've helped improve and optimize my client's smart contract for 20%+ lesser gas fees than ever.

I may be a great fit if you are thinking of any of these:
✅"There's a hundred on the line and I want the BEST, who is passionate about success along with his client's success"
✅"I want someone who will happily walk me through every step of the smart contract interaction"
✅"Gas cost is too much! I want Gas amount as less as possible"
✅"I know how blockchain works, but I want a professional and make my smart contracts 100% secure"
✅" I'm not an Ethereum expert, and I don't have time to mess around with Dapps"
✅"I want someone who works with the old as well as the Latest Solidity Version, contract design standards, and provides a Large number of tests to check all code"
✅"I need someone to take this project and get it done RIGHT - ASAP!"
✅"The last Dapp we developed was embarrassing - I don't want that ever again."

🖐Some of my previous client's quotes about me:
✔️"...Excellent Technical Skills and Positive Attitude. He was very dedicated and he did his best to make sure that the project objectives were met... This is the right guy for the job (seriously, he really is)!..."
✔️" super flexible and is able to work towards really really hard timelines... went out of his way to make any adjustments and feedback work!... "
✔️"...Great at communication and went above and beyond to complete the requirements to the finest details..."
✔️"... very hard worker... communication is fast... passionate about his profession... Likely the top 3 most professional freelancers I have worked with..."

Working with me, you will
💎Stop struggling with vulnerability, and reduce gas fees while deploying as well as interactions.
💎Maximize your Dapps security, also best-in-class followUps.
💎not have to hire a back-end developer, front-end developer, and solidity developer (I'm full stack)
💎You will get a script to lend, deposit, borrow, withdraw, etc across most of the Dapp Protocols. (like Aave, Uniswap, and PancakeSwap)
💎You will work with someone who is flexible with Python, Javascript, Brownie, Hardhat, NextJS, and Foundry.

🖐My skills & expertise in Blockchain:
- Smart contract with EVM-compatible Solidity language
- Experience with Chainlink and OpenZeppelin
- Dapps & smart contract security
- Token Launches (ERC20/BEP20 - Mintable - Burnable - Reflections - TxFee- Whitelist- Blacklist) also /IDO / ICO for tokens via ETH/ERC20
-NFTs (ERC721 / ERC1155). Standard NFTs with Whitelist/Royalties/ Presale / Public Sale/ Dutch Auctions/ IPFS Hosting/ Dynamic NFTs
- Full-stack blockchain developer. Experience in both Python (Brownie) and Javascript (Hardhat) & NextJS, as well as the latest framework Foundry.
- Script/Program for deploying/interacting with smart contracts as well as Protocols like Aave, UniSwap, PancakeSwap, etc. in both Python & NodeJs

I've spent a considerable amount of time designing projects from scratch, solving complex problems, rapid iterative prototyping, and implementing changes. Also, I have built hundreds of smart contract smart contracts from scratch, and written back-end scripts to deploy them. I know the strategies that professionals use to Optimized Smart contracts for a lesser gas fee as well as, to test smart contracts for every possibility of exploits.

My background in numbers:
✔️" More than 2 years of experience with all major protocols, including Aave, uni swap."
✔️"I developed numbered of Dapps, scripts for protocols, and tokens (ERC20, BEP20, ERC721, ERC1155)"
✔️" Worked with a couple of growing Dapp projects too! including CrowdFunding, and NFT Marketplace"
✔️"I have developed a numbered of smart contracts as well as crowd-funding Dapp, Lottery Dapp, etc."
