Proof

Engineering that shipped, not slideware.

A few of the projects behind 4TUN Hub — designed, simulated and built.

See all projects →

Simulation-driven2025

Formula FSAE car design

A complete Formula SAE vehicle taken from concept to simulation — eight sub-systems, solo, in full compliance with the competition rules.

Sustainability2025

Banana-pseudostem shredding machine

A belt-driven mono-disc shredder that turns banana-harvest waste into usable biomass — designed for Cameroonian conditions and lab-validated on real pseudostem.

Simulation-driven2023

Reverse engineering of train braking systems

Brake triangles reproduced locally for CC2200 and CC3300-AC locomotives at CAMRAIL — reverse-engineered from worn originals.

The founder

4TUN Hub is founded by Donfack Fortune — mechanical engineer, energy specialist and educator, and formerly a senior mechanical engineer at CAMRAIL, Cameroon's national railway.
