Leveraged Rust’s ownership model and type system to write reliable code and contributed to open-source projects within complex Rust ecosystems. My familiarity with Rust's tooling, such as Cargo and its package manager, has enabled me to develop and maintain production-grade applications focused on performance and safety. Developed and deployed smart contracts that were written in Solidity and Rust to handle asset management, reward distribution, and user transactions for liquidity pools, yield farming, and staking mechanisms. Developed reusable, well-documented smart contracts written in Rust using the CosmWasm framework to allow DAOs to efficiently align incentives through token swaps and liquidity provision. Develop and deploy custom smart contracts on the Solana blockchain, ensuring code quality, security, and performance. Managed the launch of tokens on the ZK-rollup platform, achieving a 60% average staking participation rate through comprehensive tokenomics strategies and secure staking platforms. Developed cryptocurrency-related features including NFT mining, staking, and swaps on Binance and Solana, and increased platform traffic by 25% using Golang for backend efficiency and smart contract integration. Used Rust to enhance the security and performance of smart contracts on Ethereum and EVM-compatible blockchains, improving staking mechanisms and reducing latency by 25%. Provided expertise in the transition to and maintenance of Proof of Stake chains, contributing insights that improved network stability and reduced staking-related issues by 20%. Developed leverages flash loans to exploit price inefficiencies across various cryptocurrency exchanges. By executing arbitrage trades within a single transaction, the bot aims to capitalize on temporary market discrepancies.

Wrote smart contracts on various blockchain platforms including Ethereum and Hyperledger Fabric to fine-tune the business logic and meet various business requirements. Leveraged Rust to implement efficient, low-level blockchain components for Ethereum and ZK-rollup scaling solutions, leading to a 50% reduction in gas fees and improved transaction throughput. Facilitated the integration of Layer 1 (Ethereum) and Layer 2 (off-chain VM) components, ensuring seamless communication and synchronization between the layers. Defined blockchain solution architecture for energy trading platform and while preparing gas efficient smart contracts for Ethereum Blockchain. Developed a stable and efficient trading bot and integrated it with Solana-based decentralized exchanges (DEXs) and wallets. Developed a high-performance hybrid architecture that combines on-chain custody and off-chain matching, leveraging advanced databases and programming languages such as Go, Lua, Rust and Solidity. Utilized Node.js, Golang, Rust and AWS to build a scalable network interface - scalable RESTful APIs. Rebuilt the infrastructure by designing, building, and maintaining a state-of-the-art Geth-based Ethereum node, increasing transaction throughput and improving network stability across the ecosystem. Optimized the core ABCI message handlers (CheckTx, DeliverTx, BeginBlock, EndBlock) to ensure efficient transaction validation and processing, resulting in a 30% improvement in transaction throughput. Created comprehensive testing strategies, including unit tests and end-to-end tests, ensuring the reliability and robustness of cross-chain applications.

Implemented best practices such as thorough testing, formal verification, and using established libraries to ensure the security and reliability of smart contracts. Established a seamless payment system that integrated cryptocurrency payments via MetaMask and enabled NFT purchases with credit cards, increasing user adoption by 40% and facilitating over $1 million in transactions within the first quarter. Ensure compliance with procession of energy transactions and nodes are in sync with smart contracts and IoT database. Motivated user engagement by 30% by integrating multiple wallet connections like MetaMask, Phantom, and HashPack across various DApps. Facilitated over $20 million in token sales and staking for ERC20, BEP20, SPL, and other tokens, attracting a community of 25,000+ investors. Implemented advanced NFT features using ERC-721, ERC-1155, and ERC-2535 standards, enhancing the functionality and upgradeability of deployed contracts. Managed the development of a marketing campaign service platform and Discord bot, improved the process with Golang, and increased user traffic by 3 million using the Discord bot.

Created and integrated RESTful APIs with Node.js and Express.js, facilitating real-time data synchronization between the Manufacturing Optimization Platform and other internal systems, ensuring accurate and up-to-date information across all departments. Developed a custom order processing workflow in Node.js, automating the entire order lifecycle from order placement to fulfillment, resulting in faster processing times and reduced manual errors. Engineered a dynamic and user-friendly dashboard in React to provide real-time insights into production metrics, inventory levels, and logistics, enabling better decision-making and resource management. Developed secure user authentication and permission management features using Node.js and Express.js, allowing organizations to manage user roles and access levels effectively. Developed Sou Server, a Dialogflow bot with an external Node.js API for business logic, along with an admin interface powered by React, Redux, and Apollo. Created the front end of an invoice management app in React, featuring full responsiveness, custom inputs, and dynamically generated pages. Designed, engineered and built a responsive Angular frontend supported by a thin PHP Drupal backend for one implementation of a high-end corporate website. Built data content based on the MySQL PHP Smarty plugin library framework that is still used by many websites.

Developed and maintained a robust suite of software applications that deliver dynamic and responsive frontend interfaces using React.js, efficient and scalable backend APIs using Flask, and seamless user experiences and robust performance using PostgreSQL. Led the entire SDLC leveraging a comprehensive technology stack including JavaScript, TypeScript, React, Redux Saga, Redux Thunk, Gatsby, npm, Node.js, Express, Lambda functions, and Serverless frameworks. Built a frontend for an invoice management app in React that features full reactivity, custom inputs, and dynamically generated pages. Designed a dynamic and user-friendly dashboard in React that provides real-time insights into production metrics, inventory levels, and logistics, enabling better decision making and resource management. Improved app performance by reducing unnecessary API calls by 95% using React Query’s caching strategy. Played a key role in developing Toggl’s time-tracking application using React (16.13.1) on the front-end, ensuring a smooth and intuitive user experience across all devices with responsive design and performance optimizations.
