Solving what matters

Fullstack Soft

AI-first engineering services

We put AI to work in your real processes, and give you the platform to keep it under control.

Custom software, consulting and AI, built and operated by the same team.

Clients in the United States, Spain and Latin America.

Aviation, airlines, insurance and software.

AI is already inside companies, but without a process: each team uses it in its own way, and nobody knows what it cost or what it changed. We close that gap.

What we do


We find the exact step of your process where AI helps — drafting, classifying or searching — and build it into a cycle that a script checks and a person approves, with the cost measured.

​


We started as a custom software company, became a consulting firm, and today work AI-first: the same team designs, builds and operates what it delivers.

​

Three ways to work with us.

AI in your processes

We pick the step where AI adds value and build it with controls that no prompt can bypass.


What we build stays in your infrastructure, with the model provider you choose.

​

Result: AI that moves from pilot to process, with a number behind it.

Forward-deployed engineers

An engineer who joins your team and takes a requirement from start to finish.


We work with AI-DLC, the AI-Driven Development Lifecycle created by AWS: specification first, AI to build, a person to approve.​​

​

Result: faster delivery without losing control of quality.

​

Custom software & modernization

Custom systems and integrations with what you already run.


Modernization of legacy code, with AI where it helps and tests that prove it works.

​

Result:  modern software your team can operate.

Fullstack Nexus

Our AI control and governance platform. One point between your applications and agents and the AI providers and tools they use: it controls what happens, measures what it costs and leaves signed, verifiable proof. Born from putting AI into production for our clients.

How we work

We adopt AI-DLC, the AI-Driven Development Lifecycle created by AWS, with a person in the loop at every step.

Specification first

Before any code

We write down what has to happen and how we will check it, before the AI builds anything.

A person approves

Human in the loop

AI proposes, drafts and classifies; the decision always carries a person’s name and is recorded.

Measured, and it stays with you

No promise without a number

We measure before promising. What we build runs in your infrastructure, with your repo and your tools.
