I turn complex machine data into decisions.

I’m Jihad Karaki. I work across vibration diagnostics, signal processing, predictive maintenance, and practical software, translating engineering evidence into tools people can use.

About

Engineering first.
Useful by design.

Mechanical systems, data, and software belong in the same conversation.

I’m a mechanical engineer with a PhD in Mechanical Engineering, Sustainable Mobility, from Politecnico di Milano, completed in May 2026. My experience includes railway diagnostics, condition monitoring, vibration analysis, signal processing, and building practical tools around complex technical work.

I founded MetaEngineers Hub as my research and development space: a place to explore engineering ideas, prototype software, and share selected public projects. It is the umbrella for the work here, not a substitute for the projects themselves.

Impact reported in my CV from work at ATM Milan.

ATM Milan · diagnostics architecture

Monitoring that connects assets, signals, and decisions.

I designed diagnostics architecture spanning three metro lines and roughly 100 km, covering 120 trainsets, and managed a team of two engineers. The program recorded a sevenfold reduction in vibration-related rail and wheel damage events within one year. ATM Milan role concluded in September 2026.

Clear boundaries.

The portfolio is static and has no private server keys. Some apps contact their map or data providers directly from your browser. If an app requires a paid API key, it should ask you to supply your own, and keep it in your browser. Read each app’s notice before use; external providers may receive ordinary requests such as map tiles or routes.
