Back to original languageAbout Hassan
With 7 years of experience in DevOps and database administration, I combine this expertise with a solid background in web development. I work across the entire chain: from cloud infrastructure to the user interface.
🚀 What I do concretely:
DevOps & Cloud: automation with Terraform, Ansible; CI/CD with GitLab and ArgoCD; Kubernetes monitoring via Prometheus, Grafana, Thanos; AWS cloud (EC2, RDS, S3, DMS, IAM…).
DBA: expert administration of Oracle, PostgreSQL, MySQL, SQL Server databases; high-availability clusters; complex migrations to the cloud (over 100 databases migrated).
Fullstack Development:
Development of several e-commerce sites with MedusaJS (headless architecture, Node.js APIs, workflow customization).
Creation of showcase websites and modern SaaS applications with React and Next.js (dynamic frontend, API integration, SSR, SEO, Auth, dashboards...).
Backend programming in Golang, Python, Node.js (REST API), and frontend JavaScript/TypeScript, React.
❤️ What I like:
Designing scalable, maintainable, and secure solutions.
Working on high-stakes technical projects: architecture redesign, cloud migration, SaaS platforms, complex e-commerce.
Collaborating with multidisciplinary teams to deliver faster, more stable, and smarter.
🎯 My goal:
To leverage my DevOps, DBA, and Fullstack skills for ambitious and structuring projects. I have a particular interest in e-commerce and SaaS platforms, as well as complex cloud environments.
