Software & AI
for business.

Valentín Álvarez LamasFreelance software & AI engineer

I’m a freelance engineer. I build and run reliable systems for companies: internal tools, integrations between the software they already use, and AI that holds up in production. I work directly with the people who run the business, and I stay on after launch.

PIPELINE

↑ it works. run the pipeline one step at a time, then ship it.

I like boring, reliable software: the kind that runs every day without anyone having to think about it. I scope the work in writing, ship it in small milestones, document what I build and keep it running after launch. And you always talk to me, the person writing the code.

The 50-second version.

Why more people is not the answer, and what software that does the work looks like.

01INTERNAL TOOLS

Internal tools. An admin panel for your operations team, an approval flow for purchases, a dashboard your managers actually open.

How I build itA web app on top of the data you already have, with roles and permissions from day one, deployed in your own accounts.
What you getA tool your team uses every day, documented, with a walkthrough so anyone can pick it up.
02INTEGRATIONS

Integrations. Store orders landing in the ERP, closed deals in the CRM turning into invoices, a report in your inbox every Monday.

How I build itConnections through the APIs of the tools you already pay for, with retries, logs and alerts built in.
What you getData that stays in sync without anyone copying it, and an alert the moment something breaks.
03AI IN PRODUCTION

AI in production. Reading invoices and contracts into structured data, sorting incoming requests, answering questions from your own documents.

How I build itLLM pipelines tested against a set of your real cases, with a person reviewing the results the model isn’t sure about.
What you getAccuracy you can measure, costs you can predict, and a system that is monitored after launch.
04ONGOING

Ongoing engineering. Keeping what already runs healthy, fixing what breaks and shipping the next improvement every month.

How I build itA fixed number of hours each month for monitoring, updates, fixes and planned work.
What you getA senior engineer who already knows your system, and a response time in writing.
