About
What started back in high school as a simple experiment has grown into my true vocation. Today I work as a software engineer and AI engineer: I design and build scalable systems with a focus on architecture, thoughtful design and sound engineering practices, and I apply artificial intelligence to improve the way software gets built.
I am currently working as a Frontend Engineer at Infoport Valencia, where I contribute to the development of digital solutions that optimize port logistics operations. My role involves designing accessible, scalable, and user-centered interfaces with Angular and TypeScript, supported by technologies such as SCSS, RxJS, and custom component libraries. I also integrate AI-assisted development tools into the workflow to accelerate development, refactoring, and code review tasks while maintaining high quality standards.
Between 2023 and 2025, prior to joining Infoport, I dedicated a period to applied research and independent development focused on the convergence between frontend architecture and AI engineering. During this phase I designed and prototyped four open-source solutions: Attention Matrix Explorer, an interactive visualization of transformer attention matrices with D3.js and Web Workers; Semantic Search Engine, a corporate semantic search engine with PostgreSQL, pgvector and HNSW indexing; Cognitive Agent Orchestrator, an agent orchestrator with the ReAct pattern and real-time SSE streaming; and Token Cost Analyzer, an LLM prompt cost and tokenization analyzer that runs entirely in the browser thanks to WebAssembly.
Since 2026 I have taken that work into AI agents and open source. I published prompt-forge, which now gives a team's AI coding agents shared memory reviewed through pull requests, and Candle AI, a technical analysis dashboard with a deterministic Bayesian confluence engine and an optional LLM narrative layer. I contribute to rea, an open-source project for reverse engineering with agents with more than 130,000 GitHub stars, where several of my contributions have been accepted, and in rea-lab I measure, with a preregistered study, what it adds to a coding agent. I have also published two Claude Code mods, rea-casebook and impact-radius, and complete applications such as gym-log. I am now expanding my profile into backend and databases.
Previously, I was part of NTT DATA as a Full Stack Developer intern, where I worked on the design and implementation of an employee management platform with Angular and Java. I also interned as a data analyst at Sothis, where I contributed to database analysis and design for compensation plans.
Outside of coding, you will often find me working out at the gym, hiking in the mountains, reading novels, or enjoying good company at a bar with friends.

Own projects and open-source contributions
AI Engineer (open source) - Open source
I build tools for AI agents and measure what they add, in my own projects and in open-source contributions. In rea (130,000+ stars) I have three merged PRs, which brought the real Ghidra verification on Windows back to green and moved the Claude Code and Gemini CLI checks to native Windows, plus an open PR in the MCP server's input validation (Node.js and TypeScript), design proposals and verification of other contributors' PRs with real Ghidra. In rea-lab I built a reproducible environment, 40 challenges with known answers and a TypeScript benchmark; its preregistered study of 70 Claude Code runs, graded with no LLM as judge, showed that rea did not change the solve rate, doubled time and cost, and that every cited evidence record was authentic. I have published two Claude Code mods, rea-casebook and impact-radius, with CI on Windows, macOS and Ubuntu, as well as prompt-forge and applications built end to end with agents, such as Candle AI, TestMaker and gym-log.

Projects
rea-lab
Public lab for reverse engineering with AI agents on Windows, built on rea and Ghidra. A reproducible environment with pinned versions and hashes, 40 C challenges with known answers and a TypeScript benchmark that isolates every run and grades with no LLM as judge. Its first study, preregistered and with 70 Claude Code runs, showed that rea did not change the solve rate (28 of 30 with and without), doubled time and cost, and that all 80 cited evidence records were authentic. Its data has led to issues and PRs for rea.

- Statistics (Wilson, McNemar)
rea-casebook
Claude Code mod that shows, live in a panel, the evidence rea gives the agent: the Ghidra wait, findings, open questions and the evidence timeline. Findings are recorded through a tool that rejects any evidence_id rea did not deliver, and the session exports to Markdown or to an artifact. TypeScript, 43 tests and CI on Windows, macOS and Ubuntu. Submitted to the Claude plugin directory.
- TypeScript
- Claude Code (mod)
- Model Context Protocol
- Vitest
- GitHub Actions (3 OSes)
impact-radius
Claude Code mod that holds risky shell commands before they run (rm -rf, git reset --hard, force pushes, migrations, global installs, curl | sh), shows what they would change and waits for you to press Run or Cancel. Works with Bash and PowerShell on Windows, macOS and Linux, in English and Spanish, with AAA contrast and CI on three operating systems.
- TypeScript
- Claude Code (mod)
- Bash and PowerShell
- AAA accessibility
- i18n EN/ES
Candle AI
Professional-grade candlestick charting and technical analysis dashboard that runs entirely in the browser: no accounts, no subscriptions, no data leaving your machine. Combines a deterministic Bayesian confluence engine (scoring 15+ candlestick and chart patterns across 7 signal hierarchies) with an optional AI narrative layer that explains the analysis in natural language. The LLM never overrides the quantitative engine; it narrates the results. Built with Angular 22 (Zoneless + Signals), Lightweight Charts v5, Web Workers for non-blocking computation, IndexedDB caching, Pine Script v5 export, and 160 Vitest + 5 Playwright E2E tests. Developed using prompt-forge agentic infrastructure across 9 epics as a solo developer.

prompt-forge
Shared, reviewed memory for a team's AI coding agents. When one developer's agent trips over something in the repository, it records a lesson; when the same lesson shows up for two or more people, a curation step turns it into a short rule that every teammate's agent reads, whether that is Claude Code, GitHub Copilot, Codex, Cursor or Gemini CLI. Promotion goes through an ordinary pull request, so a person always reviews it, and follows a ladder: fix the code, then add a check, then write memory, and only then create a skill. Just Markdown and git: an AGENTS.md block, four Agent Skills and a knowledge/ directory, with Bash and PowerShell installers that merge without overwriting anything and CI on Linux, macOS and Windows. Its 1.0 version was the infrastructure Candle AI was built on.
