We link field equipmentto your business software

We install and program turnstiles, payment kiosks, ESP32 boards, networks and servers, then write the applications and integrations that make them work together. One team is responsible for the whole chain.

Where we start

Problems we have already solved

Real situations from our projects. If one looks like yours, we already have a way of working for it.

[01] The application

The application works, but nobody is left to maintain it

The developer has left, the source code no longer matches what is running, and pages take minutes to load.

We rebuild the code, set up a test environment and take over development

[02] The process

Every order goes through five programs and ten e-mails

Checks with ANAF (Romanian tax authority), supplier stock, pro forma, shipping label, status updates – all done by hand.

We automate the flow, with a person in the loop only where needed

[03] The equipment

The turnstile, the kiosk and the server don't talk to each other

Good equipment, but with no link to payment, tickets or reporting.

We write the firmware and the application that connect them

How we work

We work with Claude. We say how, openly.

Claude, the AI assistant developed by Anthropic, is part of almost all our projects: as a tool we build with and, in some systems, as part of what we deliver.

The request becomes a ticket

We split it into requirements; the client approves the cost.

Analysis in a test environment

Claude reads the code, database and logs on a copy, not on production.

Change and test

Claude writes the change and tests it; we check the result.

Package with rollback

Verified files and rollback steps, recorded in a log.

The client approves

The client tests and starts the deployment to production.

What Claude does

  • analyses code, databases and logs
  • writes code, scripts, firmware and documentation
  • follows written procedures in production systems

What we do

  • decide what gets done and verify before production
  • install, wire and measure on site
  • keep the access rights, approvals and client relationship
Nothing reaches production without a test, rollback steps and a person's confirmation.

Sectors and technologies

Where we have worked and with what

We are vendor-independent: we choose the technology to fit the project, not the other way round.

First step

How we start working together

01

You describe the problem

Through the form or by e-mail. The more concrete, the better: which equipment, which applications, what isn't working.

02

We analyse and propose

You get a list of requirements, each with its own cost, and what exactly you will be able to check at the end.

03

We work step by step

In a test environment, with a log and rollback steps. You approve every deployment to production.

Frequently asked questions

What clients ask us

Do you also work on applications built by someone else?

Yes. We took over a B2B platform left without a developer: we rebuilt the source code from the version running in production and checked that it behaved identically before making any change.

Do you also install the equipment, or only write software?

We install it too. We do the wiring, installation and on-site measurements ourselves; we write the software and firmware for the installed equipment.

What exactly does Claude do in your projects?

It analyses code and data, writes the changes, scripts and documentation, and tests them in test environments. Decisions, final verification and production access stay with us.

How do I find out what it costs?

We split the request into requirements, and each has its own cost, which you approve before any work starts.

Contact

Tell us what needs connecting

A device that doesn't communicate, a process done by hand or an application without a developer. We reply with a concrete proposal.
