Hi 👋 My name is Ouail, also known as BjornBug

Smart contract Developer & Web3 Security Researcher

👨🏻‍💻 About Me:

I'm a Junior DeFi Developer and Web3 Security Researcher based in 🇸🇪 Sweden. I have 2 years of experience as a full-stack blockchain developer and 2 years of experience as a front-end developer. I specialize in:

  • EVM-based technologies
  • Smart contract development
  • Unit testing
  • Security reviews

I have professional experience working on various Web3 projects, including oracle integrations (Chainlink, Pyth Network), as well as AMMs, derivatives, and lending and borrowing protocols, I've also reviewed multiple DeFi protocols through private audits and public contests on Code4rena, Sherlock, and CodeHawk.

A year ago, I decided to move away from full-stack blockchain development to specialize in developing and reviewing complex DeFi protocols. I'm now focusing exclusively on DeFi, aiming to expand my knowledge in this exciting and innovative field.

I'm currently seeking internship or junior position opportunities as a DeFi developer to continue growing and developing my skills in this area.

Feel free to connect and DM me for opportunities on X, or reach out via Gmail: ouailtbytes@gmail.com even for simple questions :)
