About

Technical leadership grounded in engineering.

I'm a software engineer and engineering leader based in Tunisia. I started with software development internships in 2019, then built web and mobile products, APIs and deployment workflows before moving into engineering leadership. Today, I lead APIs, SDKs and portal delivery at VRTX, an embedded finance company.

I'm most engaged by problems that sit between software architecture, infrastructure and product delivery — the decisions that make a platform easier to build on and a team better able to ship it.

Independent infrastructure and AI exploration.

Outside production work, I use a personal lab to experiment with infrastructure, self-hosting, automation and local AI. It keeps the operational side of engineering close at hand.
