Hey, I’m Cheker, a software engineer from Nabeul building mobile, backend and AI systems since 2015.
I team up with ambitious founders, product teams and engineering leads to turn messy internal problems into mobile apps, backend systems and AI tools that actually ship — and that the next engineer can own.
Every cell is evidence, not decoration — open one to see where it shipped. Starred cells are where I go deepest.
MOBILE

The lanes, the platforms, the jams — everything outside engineering and software. The engineering catalog itself now lives on the shelf: twenty-six volumes bound on the shelf you can open — and the complete archive lives right beside them.
I'm here to make the complicated feel obvious.
No shortcuts — just explicit contracts, tested flows and a release path someone else can run.
From first prototype to production release, I design and engineer mobile and web products that earn attention and turn it into daily use.
From schema to service boundary, I build backends and data models that stay fast, predictable and easy to hand to the next engineer.
From on-device models to worker pipelines, I ship AI systems that stay explainable, guarded and owned by a human.
From the first pipeline to the runbook, I treat release, monitoring and handoff as part of the product — not an afterthought.
Let's build something that ships.
