I build digital products with calm and purpose.

I build and modernize web products across frontend, backend and CI/CD. In my work for BBVA, I apply Vue.js, React, Python and agentic tooling to improve performance, maintainability and delivery.

Work experience

  1. Software Developer and Consultant at Minsait (Indra)

    Maintenance and implementation of improvements for BBVA's internal projects. Feature development, unit testing and CI/CD.

    • Reduced load times by 35% across 4 BBVA internal apps with over 10,000 daily users, refactoring data-fetching layers and implementing virtualised rendering for large data volumes.
    • Led the migration of 3 critical apps from Vue 2 to Vue 3, cutting technical debt by 40% and ensuring long-term maintainability across a 12-person team.
    • Improved React rendering performance by 15% (measured with Lighthouse) by removing unnecessary re-renders and reorganising the component architecture.
    • Established unit-testing standards on legacy code, raising coverage from 12% to 65% and reducing production incidents by 20% in the first quarter.
    • Designed and shipped agentic AI architectures (Claude Code, MCP protocol) that standardised the team workflow and cut mean feature delivery time by 25%.

AI Engineering

How I use agents day to day with a real team — not on a demo.

I work with agents inside the repo: I use them to code, review and operate, the same as any other tool on the team.

Claude Code, MCPs and Agent Skills are the core. OpenCode and Copilot CLI for one-off jobs. Harness Engineering as the discipline.

Agentic stack in use

These are the tools I rely on to write code, open PRs and operate on real repos every week.

  • Claude Code
  • OpenCode
  • GitHub Copilot CLI
  • MCPs (Model Context Protocol)
  • Agent Skills
  • Harness Engineering

How I plug it into the team

The model is not the bit that matters — what matters is having the workflow versioned inside the repo. Per-project AGENTS.md, reusable skills, specialised sub-agents and event hooks so anyone on the team can pick it up on day one.

  • AGENTS.md per repo
  • Versioned Agent Skills
  • Specialised sub-agents
  • Event hooks
  • MCP servers
  • PR templates

What we got out of it

The numbers we pulled when we actually adopted it inside a real team at BBVA.

  • -25% mean feature delivery time
  • Standardised workflow across a 12-person team
  • Vue 2 → Vue 3 migration with agentic support (-40% tech debt)
  • Test coverage 12% → 65% with agentic assistance

Agent Skills

Skills I've written so my agents work the way I would.

01Repository (opens in a new tab)

better-init

A sharper /init for coding agents: it analyses established projects or interviews empty ones to produce a short, high-signal CLAUDE.md or AGENTS.md.

Install

npx skills add PabloViniegra/better-init
02Repository (opens in a new tab)

setup-graphify

Integrates Graphify into any project with one command: installs the tool, configures instruction files, Git hooks and ignores, then builds the initial graph.

Install

npx skills add PabloViniegra/setup-graphify
03Repository (opens in a new tab)

architecture-advisor

Recommends and persists the right architecture from a project’s stack and domain, or audits an existing one and proposes an incremental migration.

Install

npx skills add PabloViniegra/architecture-advisor
04Repository (opens in a new tab)

tell-me-the-domain

Reconstructs the business domain of an unfamiliar codebase using the repository as its source of truth and produces onboarding guides for the project.

Install

npx skills add PabloViniegra/tell-me-the-domain
05Repository (opens in a new tab)

clean-my-code

Audits code quality, maintainability, testability, and scalability with evidence, prioritizes findings, and waits for explicit approval before editing.

Install

npx skills add PabloViniegra/clean-my-code --skill clean-my-code
06Repository (opens in a new tab)

improve-prompt

Transforms vague dev requests into precise, implementation-ready prompts for coding agents. Preserves explicit decisions, makes repo inspection the first step, defines observable completion criteria.

About me

How I make decisions and what I bring to a team.

I connect interface, logic and deployment so the product works today and stays maintainable tomorrow.

Before changing code, I understand the architecture and the business problem. That gives my recommendations the context they need.

I prioritize
Quality and repeatable releases.
