Our own product
Domium
A property management platform for real estate agencies, their owners and their tenants.
Domium
Real estate operations, clearer
Live and growing
Domium separates the public storefront from reserved operations. Agencies get a branded microsite and a public listing window; owners, tenants and providers each enter only the workspace that belongs to them. Contracts, payments, maintenance, documents and per-property accounting live in one place, on a single record per property that everyone works from.
- Public listing window and branded agency microsites
- Contracts, payments, receipts and automatic reminders
- Maintenance work orders with providers and photo evidence
- Owner and tenant portals with magic-link access
- Per-property accounting, cash flow and downloadable reports
- Applied AI: tenant FAQ, contract drafts, maintenance triage, pricing hints

How we work
Short cycles, with everything in view
Scope, budget and quality stay visible from the first conversation until the system runs on its own.
01
Understand
We start with your process and your constraints, and let those pick the technology. You get a written scope, a budget range and a plan.
02
Design
Architecture, data model and interfaces agreed before the first line of code. Decisions are documented and reversible.
03
Build
Short iterations with something demonstrable at the end of each one. Tests and CI/CD are in place within the first week.
04
Operate
Monitoring, documentation and a clean handover. After that we keep running it, or your team takes over with everything it needs.
Track record
More than ten years of client work
Before Domium there were projects for companies in Córdoba. Much of how we build today comes from them.

Developments platform
A public catalogue for a construction company, with a back office for the sales team to publish developments, units and availability without touching a developer.
- Web platform and content back office
- Development, unit and lead management
- Responsive, SEO-ready front end
Education
Institutional site & enrolment
An institutional web presence for a technical training institute, with course listings and an enrolment flow that replaced manual spreadsheets.

- Inspection and finding tracking
- Compliance documents and reports
About Arsysco
Started in Córdoba, engineering ever since
Arsysco began in 2014 in Córdoba, Argentina, building web applications for local businesses that needed software fitted to their reality and their budget. Those first clients taught us to understand the problem before writing code, and to leave behind something they could maintain without us.
More than a decade later the work has grown into data platforms, cloud infrastructure and applied AI, informed by years of engineering inside financial institutions, consultancies and product teams in Europe.
The studio is deliberately small and works without intermediaries.
