πŸ“¬ About Me

I'm a full-stack developer with a passion for creating modern, clean, and decentralized applications. With expertise in MERN, Next.js, and Solidity, Rust, I have successfully built Staking apps, dApps, DAOs, e-commerce platforms, and enterprise applications. I am always keen to learn about the latest technologies and use them to solve real-world problems. Currently diving deep into the Web3 world with Solidity, Rust, and blockchain technologies.

Additionally, I have extensive experience with React Native and modern mobile applications, creating responsive and high-performance apps that work seamlessly across both iOS and Android.


πŸ§ͺ Unit Testing

To ensure the reliability and security of both web applications and smart contracts, I implement unit testing using the following libraries and frameworks:

  • Web Application Testing:

    • Jest: Used for unit testing and integration testing of React, Next.js, and Node.js applications.
    • React Testing Library: Helps test React components in an environment close to how users interact with them.
    • Supertest: Used for testing RESTful API endpoints.
  • Smart Contract Testing:

    • Hardhat: Provides an environment for compiling, deploying, testing, and debugging Ethereum smart contracts.
    • Mocha: Used with Hardhat for writing tests in a simple and efficient manner.
    • Chai: An assertion library that integrates with Mocha for testing smart contract logic.
    • Ethers.js: Used to interact with smart contracts during tests and perform blockchain-related operations.

These tools help ensure that both the frontend, backend, and smart contracts are thoroughly tested and perform as expected.


πŸ† Projects

Here are some of the projects I've worked on:

  • Staking Platforms (MERN & Web3): Developed staking mechanisms for decentralized finance (DeFi) platforms, allowing users to earn rewards while providing liquidity to the ecosystem.
  • Betting Apps (MERN & Web3): Developed decentralized and secure betting platforms with smart contract integrations.
  • dApps (Decentralized Applications): Built several Web3-based applications for different industries, integrating blockchain for secure, trustless interactions.
  • DAOs (Decentralized Autonomous Organizations): Implemented governance systems, voting mechanisms, and decentralized decision-making on the blockchain.
  • E-commerce Platforms (MERN): Created e-commerce solutions with a seamless user experience and blockchain payment integration.
  • Enterprise Applications (MERN & Postgres): Worked on large-scale enterprise applications with modern UI/UX design and scalability.
  • Voting Systems (MERN & Web3): Built secure and transparent voting applications leveraging blockchain for verifiable and tamper-proof results.
  • Custom Web3 Projects (MERN & Solidity & Rust): Developed custom smart contracts and dApps tailored to specific business requirements, including token creation, NFT marketplaces, and more.
  • Mobile Applications (React Native): Developed cross-platform mobile applications with React Native, focusing on high performance and user experience. Delivered apps for e-commerce, social networking, and utility purposes.
