Vortex-Soft designs ERK+: 19 modules, web + iOS + Android, live camera, Mobile Money, digital vault.
Every brick laid, every franc spent, every signed document — visible in real time.
Technologies that value performance, clarity and reliability — chosen for West African networks.
The four pillars of ERK+

The site manager's daily journal, worker attendance, incidents, executed quantities — documented from a smartphone, even on unstable 3G.

The building site visible live from Paris, New York or Dubai. Adaptive streaming that crosses unstable mobile networks, access strictly controlled by role.

Land titles, permits, notarised contracts: encrypted file by file, certifiably timestamped, impossible to silently tamper with.
Founded by three Senegalese engineers, Vortex-Soft builds multi-role platforms proven in production — including eCampus, the virtual campus for francophone Africa.
We have already built every block ERK+ requires: Mobile Money, live video, offline 3G, multi-role access. ERK+ assembles our proven blocks on a new trade.
Adama Niasse (CEO, principal engineer), Fatima Amadou Diop (full-stack & UX/UI) and Massar Samba (full-stack & mobile) — the team that codes is the team that signs.
Every brick counts. Every franc too.
