Rio Grande Valley, Texas
Systems that outlast the engagement.
Celvex Technology builds multi-tenant business platforms, migration tooling, and cloud infrastructure. We work the way good internal engineering teams work — schema first, tenant isolation enforced at the database, decisions written down before code.

Software you can buy today
Finished, sold, and in customers' hands — not a roadmap item.
Flyer Studio
ShippingOne self-contained HTML file that opens in a browser and runs with no install, no account, and no network calls at all. Eleven typefaces including the ones already licensed on the machine, seven independently controlled colour roles, three page formats with cut guides, English and Spanish on the same sheet, and every project saved as a plain .json file the customer keeps. Developed and owned by Celvex; published and sold by Howling Moon Creations, mirroring the Arcovex licensing pattern.
The method
What if is never a limiting factor.
Every product on this page started as a question someone decided was worth asking. The question is not asked to find a reason something cannot be done — it is asked to find one reason it might be possible. Constraints are the terrain, not the destination.
What we do
Four things, done properly
A deliberately narrow practice. We turn down work outside these lanes rather than learn on your budget.
Platform engineering
Multi-tenant application architecture on TypeScript, PostgreSQL, and Azure. Tenant isolation, RBAC, and audit designed in from the schema up rather than retrofitted after the first customer.
Enterprise migration
End-user computing and workload migration — discovery, dependency mapping, wave planning, and cutover. Delivered on real estates, not reference architectures.
Microsoft 365 & Entra ID
Tenant architecture, conditional access, identity governance, mail authentication (SPF, DKIM, DMARC), and break-glass design for organisations that have outgrown default settings.
Applied AI
Model routing, retrieval, and tool governance for teams that need AI in a production path with auditability — not a demo.
The platform
One foundation, not one-off builds
Every Celvex product runs on the same platform. That is why a second product costs a fraction of the first — and why a fix to tenancy or audit lands everywhere at once.
Praxis
In production useA TypeScript service platform providing tenancy, role-based access control, auditing, authentication, notifications, accounting, calendaring, CRM, and support as composable packages. Row-level security is enforced at the database, not the application layer, so tenant isolation cannot be bypassed by a coding mistake.
NexiVex IQ
Phase 1 completeRoutes requests across multiple model providers behind one interface, with a versioned skill registry and full request auditing. Deployed on Azure Container Apps. NexiVex IQ is the software half of a system built across three group companies.
Products
Built on it, in the open
Software we own and operate, not case studies about someone else's.
LotIQ
In developmentInventory, deal jackets, and title workflow built for independent dealers — English and Spanish throughout, not bolted on. Designed against Texas title and registration process first, with a defined path to neighbouring states.
CxVehere
Beta — round 2Discovery, planning, and cutover tooling for desktop and virtual desktop migrations, built out of real enterprise migration delivery rather than theory.
