Hi 👋, I'm
Hamza Missaoui
> Lead Full-Stack Engineer @DevScale·Cloud·DevOps·AI/GenAI·IT Consulting
I build enterprise-grade SaaS and cloud-native platforms, plus AI features that hold up in production.
I'm a full-stack engineer and founder of DevScale Digital Solutions, based in Tunis. For 5.5+ years I've taken products from architecture to production, most recently modernizing a SaaS platform that serves 10,000+ devices for brands like Shell, HP, Carrefour and Nissan.
I work across TypeScript, Next.js, Node.js and Python (Django, FastAPI), deploy on AWS, Azure and GCP with Docker, Kubernetes and Terraform, and care a lot about secure APIs (OAuth2, SSO, RBAC). Lately I'm building LLM-powered features too: RAG, data-extraction pipelines and agentic systems with LangChain, LangGraph and MCP.
Got a project or a role in mind?
Whether it's a SaaS platform, a cloud migration or an AI feature you want in production, I'm happy to talk it through. Send me a message and I'll get back to you.
