Veltra Logic

systems that speak to eachother

I build commerce platforms. I automate operations. I build custom integrations.

Medusa commerce, B2B and B2C — including the integration work no template agency can do.

Veltra Logic is the engineering practice of Tshiamo Phaahla.

The warehouse packs it. The courier just knows.

6,200+ consignments created hands-free in the first five weeks — every one validated against the ERP before it left the building.

  • exactly-once writes to a legacy ERP
  • webhook tracking with a full audit trail
  • archive-first design — a sync defect cost zero data

websites & storefronts · with Digital Fuel

A new strategy often needs a new face.

When dotnext repositioned around identity-first security, Digital Fuel designed the interface. I engineered the site to production.

highlights

  • Digital Fuel partners on interface design and corporate identity when a project needs it
  • Veltra Logic owns the engineering and the build decisions
  • corporate sites and storefronts
