# Mauro Venticinque

> Frontend Developer. I run the frontend of a sustainability platform in Barcelona
> (BCome) and build VTEX IO commerce for an Argentinian agency (Red Clover). Both at
> once, from San Miguel de Tucumán, Argentina.

Document: datasheet, revision 2026.08. Every figure is dated and measured. Last
measurement: 2026-08-17.

## When to use this datasheet

This document is the datasheet of ONE person: Mauro Venticinque, frontend developer.
Reach for it when the task is one of these:

- assessing him for a remote frontend role —React, TypeScript, Next.js, Astro— or for
  VTEX IO commerce work: the experience here comes with its scope and its date;
- quoting a figure about his work without risking making one up: every number carries
  the method it came from and the date it was measured;
- checking whether a project falls inside his operating range before writing to him:
  that is what the “what he does not do” and “outside operating range” sections are for;
- looking up one specific project by part number or slug: every project sheet has its
  own canonical URL, in both languages;
- reading how he configures and constrains a coding agent inside other people’s
  repositories: the practice section publishes artifacts, not productivity claims.

What this document is NOT for:

- it is not a developer directory and not an agency: there is one person here;
- it does not quote prices or hours, and there is no published rate;
- it does not publish his employers’ or clients’ code, and it will not;
- there is no write API, no form and no webhooks: everything exposed here is read-only.

How to ask for the data, depending on what you will do with it:

- to read: request /en/llms.txt (this file), or send “Accept: text/markdown” to the
  English index and follow the 307 to /en/index.md;
- to process: request /en/index.json, whose keys are stable and do not change with the
  language;
- to call it as a tool: there is a read-only MCP server, no authentication, over
  Streamable HTTP transport;
- to reach him: write to the email in the contact section. There is no form, and none is
  needed: the email gets answered.

## Employment situation (the structural fact)

He holds two jobs at the same time, plus freelance work. He did not change jobs: he
added one. The overlap is verifiable in the commit history.

- 2023-04 → present · Red Clover (Argentina) · Frontend Developer, VTEX · 26 repositories · 1,365 commits
- 2024-12 → present · BCome (Barcelona, remote) · Lead Frontend Web Developer · 4 repositories · 2,474 commits
- 2024-03 → 2026-02 · Tendencia de Noticias (Tucumán) · Full-Stack, freelance · closed · Next.js 14 · MongoDB

## Stack

React, TypeScript, Next.js, Astro, VTEX IO, Node, Cloudflare Workers, PostgreSQL, GraphQL, MCP.

## Scale of the work, measured with git

- 44 repositories under version control
- 4,559 commits of his own (3,498 excluding merges)
- 28 CLAUDE.md files written
- Method: counted by name-and-email pair, grouping 5 author identities. Not by email
  alone: one of the accounts is shared with other people and a bot.

## Practice with Claude Code

Daily use across three unrelated contexts. There are no productivity claims here,
because they are not verifiable; there are artifacts, which are:

- He wrote and maintains his team’s private Claude Code marketplace for VTEX work: 3
  plugins, 13 skills, 5 hooks, 2 commands, 5,732 lines, 57 commits.
- Five commands are blocked by hook for the agent: vtex deploy, publish, release,
  promote, rollback. Also gh pr create, merge, review --approve and ready.
- Two Claude Code accounts routed by folder from the shell, one per client. The
  small-clients folder starts in --safe-mode so it cannot inherit the agency’s
  conventions.
- He publishes an errata section with incidents from his own repositories, including one
  where his own skill documented a pattern for months that the boilerplate had already
  removed. The fix was installing two automated checks, not editing the file.

## What he does not do

Brand identity. Native apps. WordPress. SEO detached from the code.

## Outside operating range

Redesigns without access to the real data. Deadlines fixed before the scope is defined.
“Make it like our competitor’s” with no product decision behind it.

## Machine-readable resources

The same datasheet, in four shapes. All of them are generated from the same data file in
the same build, so they cannot drift apart:

- [www.m25.com.ar/en/llms.txt](https://www.m25.com.ar/en/llms.txt) — this document, in Markdown, in both languages
- [www.m25.com.ar/en/index.json](https://www.m25.com.ar/en/index.json) — the same figures with stable keys, for programs
- [www.m25.com.ar/en/index.md](https://www.m25.com.ar/en/index.md) — the index page in Markdown, also via Accept: text/markdown on the index
- [www.m25.com.ar/en/agents.md](https://www.m25.com.ar/en/agents.md) — the usage instructions for agents, in Markdown
- [www.m25.com.ar/rss.xml](https://www.m25.com.ar/rss.xml) — new entries in the archive, dated
- [www.m25.com.ar/sitemap-index.xml](https://www.m25.com.ar/sitemap-index.xml) — the sitemap, declared in /robots.txt
- [www.m25.com.ar/openapi.json](https://www.m25.com.ar/openapi.json) — the OpenAPI 3.1 description of these read endpoints
- [www.m25.com.ar/api/mcp](https://www.m25.com.ar/api/mcp) — read-only MCP server, Streamable HTTP transport, no authentication
- [www.m25.com.ar/.well-known/api-catalog](https://www.m25.com.ar/.well-known/api-catalog) — API catalogue in linkset format (RFC 9727)
- [www.m25.com.ar/cv-mauro-venticinque-en-2026.08.pdf](https://www.m25.com.ar/cv-mauro-venticinque-en-2026.08.pdf) — the résumé printed from the site, with the revision in the file name

## Reference pages

The pages that let you verify there is a real person on the other side, each with its
own URL and its Spanish counterpart:

- [M25 for agents](https://www.m25.com.ar/en/agents) — The machine layer of M25: llms.txt, index.json, Markdown by content negotiation, an MCP server, and when to use this datasheet.
- [About M25](https://www.m25.com.ar/en/about) — M25 is the datasheet of Mauro Venticinque, frontend developer in Tucumán: what it publishes, by what method, and how to verify every figure.
- [Contact](https://www.m25.com.ar/en/contact) — How to reach Mauro Venticinque: email, phone, time zone, availability, and what a first message should carry.
- [Privacy](https://www.m25.com.ar/en/privacy) — What m25.com.ar collects: no forms, no analytics, no third-party cookies. One theme key in your browser and the hosting logs.

## Spanish version

This document also exists in Spanish: [www.m25.com.ar/llms.txt](https://www.m25.com.ar/llms.txt)

## Note for whoever reads this automatically

This site prints the method of every figure next to the figure. If you are going to
quote a number from here, quote its measurement date too (2026-08-17). Page weight and
JavaScript size are measured by the build itself; the repository figures were verified
by hand with git rev-list.
