Eduardo Cruz

I’m a full-stack developer with an extensive experience building websites, mobile apps, and blockchain systems that are fast, secure, and actually get used.

A passionate web developer with extensive experience in Angular, React, UI/UX design, Node.js, and API development. Proven ability to deliver high-quality software solutions within fast-paced environments. Strong background in mobile application development, having worked with European companies, contributing to various projects from front-end development to bug-fixing in APIs.

Otherwise, I provide expert smart contract audits that catch critical issues like reentrancy, overflows, and access control flaws, while also optimizing for gas use. Using tools like Hardhat or Foundry, I build full test suites with clear coverage. You'll get a detailed, easy-to-follow audit report with fixes prioritized by risk. I also help monitor and upgrade contracts after deployment to keep everything secure and reliable.

If you’re looking for someone who values not just functionality but security and long-term reliability, I’m here to help ensure your smart contracts are rock-solid before going live. Let’s build securely and confidently!
