Led the design and implementation of Ethereum smart contracts for DeFi applications, increasing transaction efficiency and reducing gas costs by 15%. Engineered a Solana token with integrated staking and governance, streamlining user interactions and expanding liquidity by 360%. Integrated the Ethereum network with Polkadot using cross-chain communication tools, enabling seamless transfer of assets and data across blockchains. Conducted extensive smart contract audits and implemented security measures that reduced vulnerabilities and improved platform stability by 12%. Built and deployed secure, gas-efficient smart contracts for yield farming and staking protocols, improving transaction throughput by 24%. Optimized decentralized exchanges (DEX) by implementing custom fee structures, increasing platform revenue by 180% in a 3-month period. Mentored and guided a team of blockchain developers, ensuring best practices for secure smart contract coding, testing, and deployment. Worked closely with product and design teams to integrate blockchain features into user-facing applications, enhancing user experience and adoption.

Built and deployed smart contracts on Ethereum and Solana, focusing on DeFi, NFTs, DAOs, and cross-chain interoperability using Solidity, Rust (Anchor). Developed staking platforms with token staking, reward distribution, and vesting logic, utilizing ERC-20 and SPL Token standards for cross-chain DeFi solutions. Integrated Chainlink CCIP, LayerZero, Wormhole, Axelar for cross-chain communication and interoperability, improving user accessibility across ecosystems. Designed backend services with Node.js, Express, Flask, MongoDB/PostgreSQL, and real-time interfaces with Web3.js, Ethers.js, and WalletAdapter integrations. Deployed applications using Docker, Kubernetes, and managed CI/CD pipelines with AWS CodePipeline and GCP CloudBuild. Developed early-stage NFT platforms and DEX integrations using Metaplex, Raydium, Serum and automated liquidity strategies.

Developed Ethereum-based dApps and smart contracts for token sales, escrows, and identity systems using Solidity, JavaScript, and Python. Implemented staking and rewards systems for utility tokens with time-based vesting and unstaking mechanisms, improving token economics and user retention. Built frontends with Angular, HTML/CSS, TailwindCSS, and Material UI, and created SDKs for third-party dApp integrations. Integrated IPFS for decentralized storage and Firebase for Web3 user management. Created developer tools for smart contract deployment and testing with Hardhat, Truffle, and Ganache. Architected backend systems with Django, PostgreSQL, MySQL, and caching layers using Redis. Documented technical workflows, wrote comprehensive guides, and contributed to open-source blockchain utilities for Web3 devs.

Created a Python script to scrape product details from e-commerce websites using BeautifulSoup and Selenium. Developed a script to automate Excel file formatting and data analysis for small business reporting. Assisted in developing Python-based scripts and applications for small-scale projects, focusing on functionality and clean code. Learned and implemented RESTful API development using Flask/Django to create basic backend services. Built automation scripts for repetitive tasks like file handling, data entry, and web scraping using Python libraries like Pandas, BeautifulSoup, and Selenium. Collaborated with clients to understand requirements and delivered simple, functional Python-based solutions. Gained experience in using Git for version control and working in an Agile-like environment.
