Hi there πŸ‘‹ I'm Zied MELLITI

πŸ’» Senior Software Engineering Consultant | Solution Architecture β€’ Full-Stack β€’ Security

I design and deliver secure, scalable, and maintainable software solutions β€” from backend APIs and distributed systems to modern frontends β€” with a strong focus on clean architecture, system design, and long-term sustainability.

  • πŸ”­ Currently working on: full-stack systems, solution architecture, and security-aware applications
  • πŸ›οΈ Expertise in: solution design, clean architecture, scalable systems, and end-to-end software delivery
  • 🌱 Continuously learning: modern frontend & backend technologies, cloud-native patterns, and application security best practices
  • 🀝 Open to collaboration: open-source projects, architectural discussions, and mentorship opportunities
  • πŸ“« Reach me: LinkedIn | Email
  • ⚑ Fun fact: I enjoy turning complex problems into simple, automated, and secure solutions

I help teams build systems that scale with confidence, remain easy to evolve, and deliver real business impact.


πŸ› οΈ Tech Stack & Tools

I work across the entire software lifecycle β€” from solution design and architecture to implementation, delivery, and long-term maintenance β€” using a carefully chosen stack focused on scalability, security, and developer experience.

My day-to-day work includes building robust backend platforms and APIs, designing modern, performant frontends, and ensuring secure, reliable data flows across systems.

Java Kotlin Spring JavaScript TypeScript HTML5 CSS SAAS Bootstrap Tailwind CSS Angular Vue.js React Astro Node.js Express.js GraphQL OpenAPI PostgreSQL MySQL MongoDB Redis Firebase Supabase ElasticSearch RabbitMQ Kafka Linux Ubuntu Docker Kubernetes Git GitHub Actions Gitlab CI SonarQube Webpack ESLint OWASP

Beyond tools, I place strong emphasis on clean architecture, security-by-design, API contracts, testing strategies, and automation, ensuring systems remain easy to evolve, safe to operate, and pleasant to work on.

This stack reflects practical, production-grade experience β€” continuously refined as technologies, teams, and constraints evolve.


🧠 Focus & Engineering Principles

I focus on building secure, scalable, maintainable systems while guiding teams to deliver real business impact. My approach blends technical depth, architectural judgment, and collaboration.

  • πŸ›οΈ Architecture First β€” design before code; modular, maintainable systems
  • 🧩 Simplicity > Cleverness β€” clarity beats premature abstraction
  • πŸ” Security by Design β€” secure defaults, least privilege, automated checks
  • πŸ“ Clean Boundaries & Contracts β€” modular APIs and responsibilities
  • πŸ”„ Design for Change β€” systems easy to evolve, not over-engineered
  • πŸ§ͺ Quality as a Feature β€” testing, code reviews, and automation drive velocity
  • πŸ’» Full-Stack & System Design β€” backend, frontend, APIs, and integrations
  • 🌐 Scalable Systems & APIs β€” REST, GraphQL, messaging, and event-driven patterns
  • βš™οΈ Developer Experience & Tooling β€” automation, standards, and productivity
  • 🀝 Mentorship & Collaboration β€” strong teams build strong systems

Solving complex problems at scale by balancing architecture, security, and developer experience.
