AI Engineer · Integrations & Automation

I put AI to work inside the systems a company already runs.

I automate operational processes with AI on top of systems that already exist: ERP, point of sale, payroll, bookings. With measured cost per call, per-role permissions and human approval before anything is written. In production, not in a demo.

About

For more than 7 years I have done one specific thing: get inside a company's operation, find where time or money is being lost, and build the fix end to end.

I did not start out writing code. I started at a help desk swapping cables, setting up servers, Active Directory and Asterisk phone systems. That period taught me something no course does: when something breaks in production, the problem is almost never where it looks like it is.

Then I rolled out NCR Aloha point-of-sale systems in restaurants and hotels across Peru. I got tired of repeating manual tasks and started automating them — installation times dropped tenfold. That became the pattern: understand the operation first, write the code second.

Today I lead Latin America integrations at Workforce.com, connecting their platform with Oracle Simphony, NCR Aloha, SAP and ADP. I am also co-owner of Diamond Hotel PMS, running in five countries.

Alongside that I study Computer Science at Universidad Central de Venezuela, where I built the School of Sciences Digital Archive: document management with an AI assistant that respects a budget, never exposes credentials, and never modifies a record without a human approving it.

I did not change professions. The profession changed its name, and I had already been doing the work.

Services

I work with companies that already have systems running and need them to start understanding each other.

Free intro call

Custom integrations

For companies with two or more systems that do not talk to each other. I analyse both ends, design the integration, build it, test it, and ship it documented with a rollback plan.

  • POS: Oracle Simphony, NCR Aloha, PixelPoint
  • ERP and payroll: SAP, ADP Workforce Now
  • Hotel PMS and channel managers
  • Systems with no API: SOAP, XML, CSV, Windows services

AI assistants on a controlled budget

AI over your own data, with no surprises in the invoice or in your security posture. Same design already running in two real systems.

  • Daily spend cap with alerts and real cost per call
  • Credentials never leave the server
  • Each user role gets its own set of available tools
  • The AI proposes; a human approves before anything is written

Operational process automation

For any operation where someone repeats by hand what a system should be doing on its own. I have done it in hospitality, restaurants, retail, payroll and institutional archives — the industry changes, the problem does not.

  • Processes that today live in spreadsheets or on paper
  • Automatic reconciliation between two systems that never match
  • Invoicing, cash control, inventory and time tracking
  • Business reports someone assembles by hand today

Technical consulting and audits

For anyone with a system that misbehaves and no idea whether the problem is the code, the infrastructure, the vendor or the process. I started in infrastructure: I can tell them apart.

  • Technical diagnosis with prioritised findings
  • Action plan with realistic estimates
  • Second opinion on third-party proposals

Frequently asked

What does an AI Integration Engineer do?

An AI Integration Engineer connects artificial intelligence to the systems a company already runs in production, rather than building models from scratch. The work is getting inside the real operation, finding the process where time or money is lost, and automating it with AI while respecting the data, permissions and budget that already exist. I have spent 7+ years integrating enterprise systems, and the last stretch shipping AI to production with cost control and human approval.

Which POS and payroll systems have you integrated?

I have production integrations with Oracle Simphony, NCR Aloha, PixelPoint, SAP and ADP Workforce Now, plus hotel PMS platforms and channel managers such as Orbe. I have also integrated payment gateways and physical payment pinpads. When a system exposes no API, I build the bridge anyway: Windows services, SOAP/XML, flat files or scheduled CSV exports.

Can a system without an API be integrated?

Yes. Most legacy systems have no modern API and are still integrated every day. The usual routes are scheduled CSV or flat-file exports, direct database reads with scoped permissions, Windows services that talk to the local software, or older SOAP/XML interfaces. I have used all four in production, including a Windows service that made Oracle hardware work with NCR software — compatibility the vendor did not offer.

How do you control the cost of an AI assistant in production?

With four concrete measures: a daily spend cap that blocks calls once exceeded, measuring the real cost per call instead of estimating it, prompt caching so the context is not paid for on every turn, and resolving reads locally so the model is called once instead of several round trips. I have this design running in two real systems.

How do you stop an AI from modifying data on its own?

With three layers. First, the AI proposes and a human approves with a button before anything is written. Second, the user role decides which tools exist: if the write tool is not available in that mode, there is no way to invoke it. Third, credentials never leave the server, so they cannot be extracted from the browser. The prompt is the first line of defence and the weakest; the real barrier is the tool not existing.

Do you work remotely, and for which countries?

Yes, I have worked remotely since 2019 with teams in Peru, Uruguay, Brazil, the United States and Venezuela. I am based in Caracas, Venezuela, and work with clients across the Americas and Europe. Spanish is my native language and I am in intensive English training.

How long does an integration between two systems take?

It depends on whether both ends expose an API and how many business edge cases exist, but a scoped integration between two systems with APIs is usually in production in 2 to 4 weeks. A legacy system with no API or complex business rules can take 6 to 10 weeks. Before committing to a timeline I run a free 30-minute diagnostic call to look at both ends.

Which industries have you automated processes in?

Across six different sectors: workforce management and payroll for a platform with 10,000+ companies, hospitality through a PMS I co-own running in five countries, restaurants with self-service kiosks and point-of-sale systems, multi-site retail, banking through a debt collection call centre whose infrastructure I restructured, and public higher education through a faculty's digital archive. The industry changes; the problem never does — someone is repeating by hand what a system should be doing on its own.
