My name is Arslan. I am a Full-stack Blockchain Solution architect and developer with 5+ years of development experience. Including the crypto exchanges (P2P, CEX & DEX), blockchain forks (NFT Marketplaces, DAO), tokens creation (ERC-20, ERC-721 , ERC-721A,, ERC1155 BEP20, SPL-TOKEN), smart contracts, ICO, Defi & IDO Using Solidity and Rust I have developed Dapp, smart contracts, and NFT's for Ethereum, Solana, Fantom and Binance Blockchain. Additionally, I'm skilled with the backend technologies like Node.js, Web3.js, MongoDB, Express JS, etc. I do Backend, Frontend, DevOps, and Deployment. 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 ★ Web Development for Custom Business Web Applications ★ Front-end and Back-end Development ★ Content Management Development ★ High-End Enterprise Web Applications ★ Blockchain Development Here is a list of technologies that I use: ★ Solidity Dapp Development ★ Blockchain- Ethereum , Solana, Fantom, Binance ★ Node.js ★ Lamp Stack, Nginx ★ MySQL, Postgres — data structure, performance tuning ★ NoSQL: MongoDB, Redis, GCP ★ Frameworks: 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 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 menos
