More About Me
About

Let me introduce myself.

Wissem Hammami

Hi, I’m Wissem Hammami — a Lead Data & Software Engineer with a multidisciplinary background spanning software engineering, data engineering, analytics, and automation. I design and build end-to-end solutions using technologies such as Angular, Node.js, Express.js, Python, SQL, MongoDB, and Power BI, with a strong focus on security, scalability, maintainability, and performance.

My experience covers the complete engineering lifecycle — from understanding business requirements and designing technical architectures to developing applications, building data workflows, automating processes, deploying solutions, and maintaining them in production. I enjoy turning complex technical and data challenges into reliable, practical solutions that create measurable value.

Profile

I approach engineering with an ownership mindset, taking projects beyond implementation to consider architecture, security, performance, reliability, and long-term maintainability. I enjoy solving complex problems, understanding how systems and business processes work, and translating those needs into practical technical solutions. Continuous learning is central to how I work, allowing me to adapt quickly to new technologies, challenges, and responsibilities.

Skills

My technical expertise combines full-stack software engineering, data engineering, analytics, automation, and production operations. I work across the complete technology stack, from application architecture and APIs to databases, data workflows, business intelligence, security, and deployment.
