We design and build custom CRM, ERP and web applications for companies that have outgrown their spreadsheets. From the database to the screen, connected to the tools you already run.
Free · No commitment · The code is always yours
At the centre is the system we build for your operation. Integrations, automation and AI are what make it work with everything else.
CRM and ERP systems, inventory and invoicing, admin platforms, client portals and mobile apps, designed around how your company actually works. Data, permissions and business rules modelled right from the start.
What we build does not live on an island. We connect it to your accounting, your payment gateway, WhatsApp and the systems that already work: one record, one source of truth.
Repetitive work becomes part of the software: approvals, documents, invoicing and alerts that run on their own, with every step on record.
AI features built into the product: reading documents, answering customers and preparing decisions. AI with judgement behind it, not AI built for the demo.
We help your business scale with technology: we look at how you run today, open your mind to ideas you had not considered and leave you with a clear path to grow. The first session is free.
A system is not handed over and abandoned. Monitoring, continuous improvement and a team that answers when it matters.
It replaced three spreadsheets and a stand-alone invoicing tool. Inventory close went from 3 days to 4 hours.
Applications, documents and approvals in one system, with files read automatically before they reach the analyst.
Staff schedules, patient history and WhatsApp bookings on one platform, with reminders that go out on their own.
A great experience. They built an automation for me and I was very happy with the result. It works really well and does what I needed. I recommend them!
Founder and CEOSantiago de los Caballeros, Dominican Republic
I am a full-stack developer, and I started RBX Codex to build the software companies need and cannot find off the shelf: CRM and ERP systems, admin platforms, corporate portals and custom management applications.
I work end to end: I sit with the team that lives the process, model the database, write the frontend and the backend, and stay with the system after it ships. In a management system the real challenge is never the screen — it is getting the data, the permissions and the business rules right from the start.
Where it makes sense, I integrate and automate what you already have instead of replacing it. And I care that the software stays maintainable, not just that it works on launch day: you get documented code, and I explain the technical decisions in language the business can act on.
Scroll: this is how a project moves, from idea to a system in production.
You see progress every two weeks in a real environment. If something is not working, you find out in week three, not in month six.
We sit down with your team, learn how it works today, and agree on what the system has to solve and how we will measure it. Free, no strings attached.
We agree on scope, architecture and a clickable prototype. You see and touch the solution before we write a single line of production code.
Deliveries every two weeks, in a real environment your team can try. No black boxes and no surprises at the end.
We measure against the goals set in the assessment. What falls short gets adjusted. What works grows with new modules.
What we build connects to what already works in your company: accounting, payments, WhatsApp, your databases. Replacing is the last option, not the first proposal.
A client who signs up on WhatsApp shows up in the CRM, in billing and on the dashboard. No copy-paste.
We integrate your current systems through their APIs instead of forcing you to migrate everything at once.
Every workflow leaves a trace. If something fails, your team hears about it before your client does.
Payments, messaging, databases and AI models orchestrated from a single layer that you control and that comes documented.
A modern stack proven in production: TypeScript, React and Next.js, Python and Django, PHP and PostgreSQL. Code that is yours, documented, with no vendor lock-in.
Not here? Write to us and you'll hear back within 24 hours, without an endless form.
CRM and ERP systems, inventory, purchasing and invoicing, appointment and patient management, lending platforms, client portals, and web and mobile apps. Each one built around how your company works and connected to your accounting, your payments and WhatsApp Business.
It depends on scope, which is exactly why the assessment is free. When it ends you get a proposal with fixed scope and a fixed price, with no costs appearing halfway through. A typical project starts with a first working module and grows in phases, each with its own scope and price.
By project. Every phase has its scope and price agreed before it starts. After delivery you can add a monthly support and evolution plan if it suits you. We do not sell loose hours.
The first useful delivery lands in 30 days or less. A complete system usually runs 8 to 16 weeks, shipped in two-week phases so you start getting value early rather than at the end.
Yes. Most of our work is remote. We operate from Santiago de los Caballeros and deliver for clients across the Caribbean, North America and Europe, fitting meetings to your time zone.
Almost always. We build on what already works and connect it. We only recommend replacing a system when keeping it costs more than replacing it, and we show you those numbers before we propose it.
You do. At the end of the project you receive the full repository, the documentation and the infrastructure access. We do not work with licences that keep you tied to us.
We offer support plans with monitoring, fixes and improvement hours. You can take one or keep just the system and its documentation. The decision is yours at every renewal.
A 30-minute conversation. You leave it with a clear scope, the first technical decisions and an honest estimate of time and cost.
