Julio Antequera Galiano

I’m a backend engineer with 15+ years of experience, focused on Ruby on Rails, high-scale systems, platform engineering and developer experience.

For nearly ten years (2016–2026) I worked at RubiconMD, a US healthcare platform connecting doctors with specialists. I worked fully remote from Seville and grew from Backend Engineer to Principal Engineer, as an individual contributor reporting to the VP of Engineering.

Backend and scale

• Built the rules engine that routes around 300,000 medical consults a year.

• Kept the Rails monolith healthy for almost a decade: upgraded it from Rails 4.2 to 8.1 and Ruby 2.4 to 4.0, with 99.99%+ uptime.

• Designed the migration for a platform merger, moving about 12 clients to the new platform.

• Delivered integrations with large healthcare partners such as CVS/Oak Street, in a HIPAA and HITRUST regulated environment.

Platform and developer experience

• Co-founded our Platform Engineering team.

• Cut CI build times to a third of the original 30–35 minutes.

• Cut disaster recovery time from about 90 to about 20 minutes.

• Built a Dependabot process that resolved 84% of production CVEs within 4 hours.

• Automated a weekly task that took three people in a meeting, down to 5 minutes for one person.

Technical direction and people

• Introduced and ran our RFC and ADR process, so any engineer could propose a change, get feedback and see it implemented.

• Mentored engineers across the team; 3–4 of them were promoted.

• Ran onboarding for new hires and gave internal talks.

Outside work, I’ve maintained Injectable, an open source dependency injection gem for Ruby, since 2018.

Before RubiconMD, I worked as a Rails developer at CookiesHQ and as a freelancer on web projects. I started my career in embedded C++ and robotics, which gave me a solid low-level foundation.

What I’m looking for: A Senior IC role on a product team, using Rails, where quality, testing and long-term ownership matter. I prefer stable, product-focused companies over hype. I work in EMEA hours. Spanish native, English C1.
