Hakam Koubaa – Blockchain Security Enthusiast & Smart Contract Auditor

I am Hakam Koubaa, a passionate Cybersecurity Master’s Student with a deep focus on blockchain security and smart contract auditing. My journey is driven by a commitment to securing the future of decentralized technologies and ensuring the integrity of blockchain ecosystems.

With a strong foundation in cybersecurity and information security, I specialize in identifying and mitigating vulnerabilities in smart contracts, designing secure blockchain architectures, and conducting thorough security audits. My expertise spans Solidity, Ethereum, Hyperledger Fabric, and IPFS, allowing me to build and audit secure decentralized applications (dApps) that adhere to the highest security standards.

Professional Experience

• Digital Transformation Lead at VIKA Immobiliere (Aug. 2023 – Present): I implemented secure coding practices and automated workflows, reducing vulnerabilities by 25% while ensuring compliance with cybersecurity standards.
• Blockchain Intern at Vetrik (Nov. 2021 – Jun. 2022): I conducted security audits of smart contracts, identifying critical vulnerabilities such as reentrancy and integer overflow. I also designed and deployed a secure blockchain architecture using Hyperledger Fabric, ensuring compliance with best practices.

Blockchain Projects

• Smart Contract Auditing: I have conducted security audits for multiple Ethereum-based smart contracts, identifying and mitigating vulnerabilities such as reentrancy, integer overflow, and denial-of-service (DoS) attacks.
• Decentralized DNS System: As part of my final year research project, I designed and deployed secure smart contracts using Solidity and created a dynamic front-end with React.
• NFT Projects: I developed secure on-chain NFTs using Solidity and HardHat, focusing on preventing common vulnerabilities, and implemented IPFS for secure off-chain storage to ensure data integrity.

Education

• Specialized Master's in Cybersecurity and Cloud Computing in IPSSI - Paris (2025-2027)
• National Engineering Diploma from INSAT (2016 – 2022): Specialized in Cybersecurity and Information Security, graduating with Highest Honor.
