Hi, I'm Mohamed 👋 I'm a Senior Full-Stack Engineer with 8+ years of experience building scalable web applications, leading engineering teams, and architecting products used by thousands of users. Throughout my career, I've worked with startups, enterprise organizations, and international teams across Germany, Austria, Ukraine, and Egypt. I've led frontend architecture, modernized large legacy codebases, designed authentication systems using OpenID Connect, and built production-ready applications from the ground up. As an Acting Tech Lead and Senior Engineer, I've been responsible for technical decision-making, mentoring developers, conducting code reviews, improving engineering standards, and collaborating closely with product and design teams to deliver scalable, maintainable software. My expertise includes: • Frontend Architecture (Vue.js, Nuxt.js, React, Next.js) • Full-Stack Development (Node.js, REST APIs, MongoDB) • System Design & Software Architecture • Authentication & SSO (OpenID Connect) • Accessibility (WCAG Compliance) • Performance Optimization • Code Reviews & Engineering Best Practices • Technical Leadership & Mentoring • Senior Frontend & Full-Stack Interview Preparation I enjoy helping engineers grow—whether that's preparing for technical interviews, reviewing resumes, designing scalable architectures, debugging challenging production issues, or leveling up their frontend and backend engineering skills. If you're looking for practical, real-world guidance from someone who's built and led production systems across multiple industries, I'd be happy to help.
