Hi, I'm Preet Singh — a passionate Full Stack Developer and Web3 Auditor with 2+ years of experience building decentralized applications and over 6 months of experience in smart contract auditing.
From shipping production-ready dApps to diving deep into smart contract vulnerabilities, I bridge the world of scalable frontend/backend systems with the security-first mindset of blockchain development. I work across Ethereum, Solana, and bring in DevOps best practices using Docker, AWS, and modern CI/CD pipelines.
🌐 Current Focus:
- 🚀 Web3 Development: Building scalable, secure dApps using Solidity, Rust, and full stack frameworks.
- 🔍 Smart Contract Auditing: Specializing in finding vulnerabilities in DeFi, staking, and DAO protocols.
- 🔧 DevOps & Infra: Automating deployments with Docker, AWS, and CI/CD workflows.
- 🧠 AI x Web3: Exploring LLMs to power auditing bots and intelligent code tools.
💡 Interests:
- Blockchain architecture & protocol-level design
- Full stack app development with focus on performance & DX
- Building AI agents for smart contract analysis
- OSS contributions & helping devs secure their protocols
During my auditing journey under the alias Raone, I contributed to several real-world security reviews across DeFi, DAOs, and staking protocols. Here's a snapshot of vulnerabilities I discovered:
