Web3 , DApp and Blockchain Developer
About this Gig
Stop wasting gas fees on inefficient contracts. Lets build secure, scalable Web3 solutions.
Hi, Im Mujtaba, a Senior Full-Stack & Blockchain Architect with 7+ years of engineering experience and 4 years of dedicated focus on the Web3 ecosystem. I specialize in bridging the gap between high-performance backends and decentralized finance. My mission is to deliver audited, deployment-ready code that protects your assets and scales with your users.
My Specialized Web3 Stack:
- Smart Contracts: Expert-level Solidity development (ERC20, ERC721A, ERC1155).
- Blockchain Networks: Deep experience with Ethereum, Solana, Polygon, and EVM-compatible chains.
- Integrations: Seamless Web3.js/Ethers.js connectivity with Metamask and hardware wallets.
- Full-Stack Power: Robust backends built with Node.js, Express, and React JS.
Why Choose My Technical Expertise? In 2026, security is everything. I don't just "write code"I architect systems. I focus on Gas Optimization to save you money on deployment and Reentrancy Protection to secure your protocols. Whether you are launching a DeFi platform, an NFT collection, or a custom dApp, I provide the engineering rigor required for a successful mainnet launch.

FAQ
What do you need from me to start the project?
To begin, I need a clear technical requirement document or a functional breakdown of your project. For Web3 tasks, please specify the target network (ETH, Polygon, Solana, etc.). For MERN applications, providing a Figma link or a wireframe is highly recommended to ensure design accuracy.
Will the smart contracts be gas-optimized and secure?
Absolutely. I use industry-standard Solidity patterns (like Uint256 optimization and efficient mapping) to minimize gas costs. To ensure security, I implement the "Checks-Effects-Interactions" pattern to prevent vulnerabilities such as Reentrancy attacks and Integer Overflow issues.
Can you integrate AI models into my web application?
Yes. I specialize in adding intelligence to Node.js backends. I can integrate OpenAI (GPT-4), Gemini, or custom LLM APIs to handle automated content generation, intelligent chatbots, or complex data analysis features directly within your MERN stack ecosystem.
Do you provide deployment and server configuration support?
Yes, I offer full deployment assistance. I can set up your Node.js environment on AWS, Vercel, or Heroku, and deploy your Smart Contracts to any EVM-compatible Mainnet or Testnet. I also ensure your environment is configured for high concurrency and enterprise-level security.
Can you connect smart contracts to a custom React frontend?
Yes. I use libraries like Ethers.js or Web3.js to bridge your smart contracts with a React/Next.js frontend. This includes secure wallet integration (Metamask, Phantom, etc.), real-time on-chain data fetching, and transaction handling to create a seamless dApp experience.
How do you ensure the application can scale for many users?
I architect systems using Modular Backend principles and optimized MongoDB indexing. This ensures your platform remains fast even as your user base grows. For Web3 projects, I implement RPC redundancy and efficient state management to prevent downtime during high traffic.
