20 years at the intersection of engineering, product and knowledge management

With strong technical foundations (Linux, networking, security, coding and AI), I've built and shipped software in very different business domains: e-commerce, mobile secure messaging, banking and tax compliance, civic and gov tech, and SaaS.

I care about UX, CX and DX. That's why shared ownership is key to me. I'm a documentarian at heart, good at explaining and redesigning complex technical systems (including sociotechnical). Lately, I've been speaking about AX (Agent eXperience) too, specifically from a docs perspective.

Known for advocating #NoMeetings: healthier remote work, with fewer meetings and better async collaboration. Because the most effective way to change how people behave is to change the system they are in, turning better ways of working into the path of least resistance.

Teaching is my second vocation. I've been doing it at university, in mentoring initiatives and tech communities, as well as coaching engineering teams and speaking at conferences.

• Event organizer, AOS 2023 · National Agile Open Space event in Jaca (agile-spain.org/aos-2023-jaca).
• Community lead, Agile Aragón (2015 to 2023) · Local agile community in Aragón, Spain. Organized the "Friday Dojos" and facilitated the GDCR 2018 (Global Day of Code Retreat), hosted by Vueling.
• Speaker mentor, Women TechMakers Zaragoza 2017 · First edition of the conference.
• Crew member, QCon London 2016 · Volunteer organizer.
• Mentor and co-founder, Senpai Devs (2015) · Mentoring program for developers (XP, Software Craft, DevOps, TDD).
• Collaborator, Zagales Hacklab (2013 to 2017) · Introducing technology to kids through hands-on workshops.
• Regional lead, Hispalinux Aragón (2013 to 2016) · Ran the association's venue in Aragón, with open source courses and talks for local communities.

Here's a selection of talks, for a full list check javirubio.net.

• Spanish national radio (Onda Cero, "La Rosa de los Vientos"): segments explaining Telegram vs WhatsApp security (2014) and the new "Cookie Law" (2013) to a general audience.

I use agentic coding on my own harness, deciding what the agent can own, what needs deterministic scripts, and what still needs my judgment. Some of what I've built that way is public:

• Transparencia ES: AI agent explaining public procurement open data in plain language, with a Claude Agent Skill as its brain. Ship for Good hackathon, 2026.
• wallapop-to-vinted: Python tool to scrape and migrate listings between marketplaces, built with Claude Code, 2026.
• jrub-web: my personal site for talks and public interventions, javirubio.net.
