I'm <strong>Akram-Ali Goulahsen (Mr Goulahsen)</strong>, a Full-Stack Developer and Cybersecurity Researcher based in Casablanca, Morocco.</p> <p>When building modern web applications, combining robust engineering with strong security practices is essential. Here are 3 quick security principles every full-stack developer should implement:</p> <ol> <li> <strong>Input Validation &amp; Sanitization:</strong> Always sanitize user inputs to prevent Cross-Site Scripting (XSS) and SQL Injection vulnerabilities.</li> <li> <strong>Secure Authentication:</strong> Implement strong hashing algorithms (like bcrypt or Argon2) for passwords and secure JWT handling.</li> <li> <strong>HTTPS &amp; Headers:</strong> Use strict Transport Security (HSTS) and properly configured Content Security Policies (CSP).</li> </ol> <p>I'm currently exploring new security research and open-source development. Feel free to check out my projects on my <a href="https://github.com/mr-goulahsen" rel="noopener noreferrer">GitHub</a> or visit my personal portfolio at <a href="https://mr-goulahssen.github.io" rel="noopener noreferrer">mr-goulahssen.github.io</a>.</p> <p>What are your go-to security practices when building full-stack apps?
