Hi, I'm Yuvraj Singh 👋

An independent developer learning and specializing in Web3 architecture, decentralized finance (DeFi), and smart contract security.

🚀 My Journey

In July 2026, I initiated a full-time, intensive study of blockchain fundamentals, cryptography, and smart contract architecture. I spent the summer learning Solidity and the Ethereum Virtual Machine (EVM). By September 2026, I transitioned from theoretical coursework and browser-based environments into active execution. I am now focused on building, testing, and auditing using professional local development toolchains.

📚 Autonomous Curriculum

To build a rigorous, production-ready foundation, my self-taught syllabus leverages industry-leading Web3 platforms:

  • Cyfrin Updraft: Deep dive into smart contract security, auditing frameworks, and advanced Foundry testing.
  • HackQuest: Interactive Web3 development and specialized blockchain ecosystems.
  • Coddy Tech: Foundational programming mechanics and logic structuring.
  • Binance Academy: Core blockchain theory, decentralized architecture, and cryptographic principles.

🛠️ Technical Stack

  • Languages: Solidity
  • Frameworks & Tools: Foundry (Forge, Anvil, Cast), Git
  • Core Focus: Gas optimization, state manipulation, vulnerability analysis, and multi-chain deployment

🔭 Currently Working On

  • Writing and deploying gas-optimized smart contracts using the Foundry toolchain.
  • Mastering advanced Foundry testing frameworks, state manipulation, and cheatcodes.
  • Preparing to launch a public portfolio of smart contract vulnerability reports soon.
