01About me

Engineeringwith intent.

Where software meets the physical world, and both sides have to work.

Computer engineer with three years of experience, specialised in fullstack C#/.NET, NestJS and Flutter development.

My work sits where software meets the physical world: real-time industrial systems, RFID and LoRa traceability, desktop applications that run production floors, and cross-platform mobile clients that put the same data in a field operator's hand.

I build on Clean Architecture, design scalable backends and REST APIs, and bring artificial intelligence in-house by integrating local LLMs, so sensitive data never leaves the premises. On the frontend, Angular and React round out complete web platforms.

Fullstack by Practice

From C#/.NET and NestJS backends to Angular, React and Flutter clients: one engineer across the whole stack.

Software Meets Hardware

RFID on metallic surfaces, LoRa long-range radio, TCP sockets: industrial IoT that has to work in the field.

Clean Architecture

Scalable backends with a strict separation of concerns, built to be extended rather than rewritten.

AI, On Premise

Local LLM integration through Ollama and Mistral 7B: intelligence without shipping data off-site.

Education

Six years at the Institut International de Technologie in Sfax, from information systems to decision-support computing.
