Our own product
Domium
A property management platform for real estate agencies. Trustworthy listings on the outside, clear operations on the inside.
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 instead of scattered across spreadsheets and mailboxes.
- 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
Small steps, working software, no surprises
A predictable rhythm that keeps scope, budget and quality visible from the first conversation to the day the system runs itself.
01
Understand
We start with your process and your constraints, not with a 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 from day one, not bolted on later.
04
Operate
Monitoring, documentation and a clean handover. We can keep running it, or hand you the keys. Your code stays yours.
Track record
A decade solving real business problems
Before Domium there were a decade of client projects. These were delivered for companies in Córdoba and are the reason we build the way we do.
Construction
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.
- Course catalogue and enrolment forms
- Administration panel for staff
- Low-maintenance hosting
Health & safety
Compliance back office
Client and site management for an occupational health and safety consultancy: inspections, findings and the paperwork each visit generates, in one place instead of scattered across mailboxes.

- Inspection and finding tracking
- Compliance documents and reports
Technology
Boring technology, used well
We pick tools that your team can still run in five years. Managed services where they pay off, plain code where they do not.

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 are still the reason we work the way we do: listen first, keep it simple, ship something that survives 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, with no layers in between. You talk directly to the engineer building your system, not to an account manager.
