Custom software development · Mexico
OaSys Factory builds custom software for processes where failure is expensive: high transaction volume, integration between legacy systems and the plant floor, and tax compliance. More than 20 years of the founder's experience across government, manufacturing, healthcare and services.
We don't sell templates or licenses. Every system is designed around the client's real process, with its volumes, its integrations and its rules.
End-to-end solution design: data model, batch and online processing, failure points and capacity. Systems built to carry sustained load, not to survive a demo.
Middleware between databases, APIs, business systems and industrial controllers. When two systems don't talk to each other, we build the layer that translates between them and leave it monitored.
Generation, validation and stamping of Mexican CFDI invoices through a certified provider, at tens of thousands of documents per day, with error handling, retries and reconciliation.
PLC programming and upgrades, SCADA systems and plant control. Process data acquisition and its connection to business systems.
Complete payroll systems: entry, exceptions, calculation, disbursement and bulk tax stamping. Proven on rolls of thousands of employees and through regulatory change.
Upgrading systems that are already running and cannot be switched off. Staged migration, without halting operations or losing the business logic built up over years.
Twenty years of the founder's career in environments where the system is part of daily operations, not an accessory.
A crime analysis system for a metropolitan public administration: incident consolidation, data exploitation and support for operational decision-making.
Inventory control for the pharmacy network of a national social security institution, plus the warehouse and picking system at its logistics contractor's distribution center.
A decade inside the plant of a global automotive corporation: upgrading control and plant systems, and automating processes with PLCs and SCADA.
Owner of a state government's payroll system: from exception entry through calculation and bulk tax stamping, under the load and deadlines a biweekly cycle imposes.
Head of backend, solution design and architecture on an airline ticket invoicing platform: payment extraction and processing, and bulk tax stamping for one airline in a single country.
Four stages, in this order. Skipping the second is what produces systems that collapse at the first month-end close.
Understanding the real flow, the one people run every day, not just the documented one. Volumes, exceptions and who touches what.
Defining system boundaries, integrations, capacity and failure points before the first line is written. This is where it is decided whether the system holds.
Working deliveries that integrate with what already exists. Nothing is built in isolation to be “connected” later.
The system goes into production and is kept there: monitoring, volume growth, regulatory change and process adjustments.
We work as readily on the business software side as on the equipment down on the plant floor — and above all on the bridge between the two.
If you have a manual process that no longer scales, two systems that don't talk to each other, or an operation running on spreadsheets, that is exactly the starting point.
