The essentials

The essentials

The Vortex-Soft proposal for ERK+, on one page.

ERK+ demands seven technical capabilities that are rare in West Africa: sealed multi-role access, native Mobile Money, live video, offline mode, an encrypted vault, performance on 3G/4G, and an architecture ready for your Versions 2 and 3.

We have already built every one of them — and one is in production, public, today: our eCampus platform. Open it before you even read this proposal. It is our strongest argument, and it costs nothing to verify.

Under construction

We build ERK+ in front of you — floor by floor, demo every two weeks.

Our stance: proof before promise

A software tender is usually won on slides. We would rather hand you, every two weeks, software that runs on an environment reserved for you. Nothing is discovered at acceptance: you have already clicked on it.

You watch the product grow. A demo every two weeks on your staging environment. Every delivered brick is testable end-to-end, across your three real client journeys.

What we deliver

  • All 19 modules in the specification — from authentication to the post-delivery warranty
  • Three applications: web (browser), iOS and Android (published on the stores), and an admin back-office
  • The required integrations: Mobile Money & card payment, live camera, e-signature, push / SMS / email notifications
  • As a free bonus: the native ERK+ desktop app for Windows, macOS and Linux

Our engineering commitments

  • Source code that is the exclusive property of ERK Group, pushed continuously to your Git repository — no lock-in to Vortex-Soft
  • The 3-second ceiling on 4G treated as a blocking gate in our delivery pipeline, measured on every build
  • Penetration testing (OWASP) and load testing at 2,000+ concurrent users before go-live — reports delivered
  • Training for your teams, complete documentation, and 6 months of free support after launch

Delivery

Go-live at M+8 — four months ahead of your roadmap horizon, with an architecture that will host your marketplace (V2) and financial services (V3) without a rebuild.

Scope. This proposal covers Version 1 exclusively, in line with the object of your tender. The architecture anticipates V2/V3; their development will be the subject of separate proposals.
