Blockchain developer | Solidity | Rust | NFT | Solana | Ethereum

Hi! I am a Full-stack Blockchain Solution architect and developer with 7+ years of development experience. Including the crypto exchanges (P2P, CEX & DEX), blockchain forks, tokens creation (ERC-20, ERC-721, ERC-721A), smart contracts, ICO, Defi & IDO Using Solidity and Rust I have developed Dapp, smart contracts, and NFTs for Ethereum, Solana, Terra, and Polygon Blockchain. Additionally, I'm skilled with the backend technologies like Node.js, Web3.js, Laravel, MongoDB, Express JS, etc. I do Backend, Frontend, DevOps, and Deployment. I work full time as a freelancer, enjoy long-term projects, and guarantee attention to detail and respect for deadlines. Are you looking for someone who will get all your things done perfectly? You have found me. - My Blockchain Specialization Areas: ★ DEXes (like Uniswap, Sushiswap, Pancakeswap, dYdX, etc) ★ NFT Minting DApps and marketplaces (Ethereum, Solana, Terra, Immutable X, and others) ★ DeFi platforms (any dApp, Binance Smart Chain, Ethereum, EOS, Tron) ★ Stock exchanges (like Binance, Coinbase, etc) ★ Wallets (crypto/fiat) ★ Blockchain block explorers ★ ICO Applications ★ IDO Applications ★ Token on standards- ERC 20, ERC 721, ERC 721A, ERC1155, BEP20. ★ Token on standards- Spl tokens ★ Web Development for Custom Business Web Applications ★ Front-end and Back-end Development ★ Content Management Development ★ High-End Enterprise Web Applications ★ Develop Custom RESTFUL API For Mobile Applications ★ Reputation Management Systems ★ Review Management Systems ★ Saas Applications ★ Blockchain Development Here is a list of technologies that I use: ★ Solidity Dapp Development ★ Blockchain- Ethereum , Solana, Immutable X, Terra ★ Node.js ★ Lamp Stack, Nginx ★ MySQL, Postgres — data structure, performance tuning ★ NoSQL: MongoDB, Redis, GCP ★ Frameworks: Laravel, React, Nextjs, Nuxt ★ Redux, Redux-Saga, Material UI, Typescript ★ DevOps: AWS, Cloudflare, Digital Ocean, Vultr, Kubernetes, CI/CD Pipelines ★ HTML, Bootstrap, jQuery, Sass, Gulp, Webpack, etc. — responsive, mobile-friendly websites ★ Server-side and client-side optimization, web applications performance tuning My approach to project execution is as follows: ★ Understanding the project requirements through calls and emails ★ Wireframing using tools like Balsamiq, InVision, Figma ★ Project Execution using Project Management Systems like Basecamp, Trello, ASANA, Active Collab, JIRA ★ The delivery basis on the milestones and ensuring that the milestone is not missed ★ AGILE Methodology: Making project sprints and delivering them on time ★ QA Assurance: All the milestones are QA'ed by QA Analyst and test cases can be provided if required ★ Deployments ★ Support & Maintenance 10 GOOD PRACTICES I FOLLOW IN CODE MANAGEMENT: 1. Commit early, commit often; every commit provides a rollback position 2. Inspect changes before committing 3. Remember the axe-murderer when writing commit messages 4. While working in a team, must commit your changes – you can’t delegate it 5. Versioning Database 6. Making extensive – detailed notes in the check-in comments about why the changes were made 7. Ensure the working file is from the latest version of the source file 8. Only Check-out the file being worked upon 9. Review every change before committing; utilize the diff function! 10. Use the ignore button for files that should not be committed, consider adding pre-commit filters to prevent the wrong kinds of files (such as accidental check-in of personal user settings docs) from entering the source control My hourly rate ($55) is the mean of all of these independent efforts from each of the skills involved and it's negotiable. English is my first language, and you can expect my communication to be prompt, polite, and friendly. I will, however not hesitate to speak out if I feel something is being done incorrectly or can be improved upon. If you are looking for a solid, detail-oriented and "DO WHATEVER IT TAKES TO GET THE JOB DONE" kind of person who never quits, adheres to deadlines, and is as reliable as death and taxes, then get in touch with me. I am looking forward to working with your exciting projects. Best Regards,
