Hi there, I'm Javier.

Building reliable, scalable infrastructure for fast-moving teams — so shipping is the default and ops is never the bottleneck.

I Am a

Over a decade designing, building, and operating cloud-native platforms. I work at the intersection of infrastructure, reliability, and developer experience — the systems and pipelines that let product teams ship fast without breaking things.

The mindset.

Good engineering is as much about how you think as what you ship. These are the principles that guide how I approach reliability, delivery, and collaboration.

Automate to eliminate toil

Manual, repetitive work compounds quietly until it owns your week. Every process that can be codified should be — provisioning, testing, deployment, remediation. The goal of automation isn't efficiency. It's preserving engineering judgment for problems that actually require it.

Deployment frequency is a health metric

How often a team deploys tells you more about its culture than any post-mortem. Small, frequent releases compress feedback loops, reduce blast radius, and make rollbacks trivial. CI/CD isn't a tooling choice — it's a signal that a team owns what it ships end to end.

The desired state lives in Git

Infrastructure defined as code is infrastructure you can review, reproduce, and audit. GitOps extends this further: the system converges to what's in the repository, not to what someone ran last Tuesday. Version control becomes the change log; pull requests become the approval process.

You build it, you run it

The handoff between development and operations is where accountability goes to die. When the team that ships is also the team on-call, the incentives align. DevOps isn't a set of tools — it's the decision to own the full lifecycle of what you build.

Failure is data, not shame

Distributed systems fail. The question is what you learn. Error budgets make the reliability contract explicit — a formal agreement between velocity and stability. Blameless postmortems turn incidents into institutional memory. Every failure should make the next one cheaper.

You can't improve what you don't observe

Monitoring tells you something is broken. Observability tells you why. SLIs and SLOs aren't dashboard metrics — they're commitments. DORA metrics measure whether delivery is actually improving over time. Without data, improvement is just opinion.

Work Experience

These are the roles and tasks that I have performed in my years of experience.

DevOps Engineer

Quadrant Travel Technologies 2022 -

As part of the SRE team, we built the cloud platform from scratch — full IaC with Terraform, GitOps via ArgoCD, and centralized CI/CD pipelines on GitLab. Reliable infrastructure that runs smooth in the background: teams own their full delivery lifecycle and deploy independently, with no gatekeepers in the way.

Site Reliability Engineer

2gether 2021 - 2022

As SRE at a regulated crypto exchange, I owned cloud infrastructure, observability, and CI/CD end to end — high availability for real-time financial operations, and infrastructure costs consistently moving down.

R&D Consultant

Yogabot 2020 - 2021

R&D engagement exploring blockchain architecture and tokenomics to support a decentralized wellness ecosystem.

Personal development

2020

Completed a long-pending university degree while deepening knowledge in investments, financial markets, and distributed ledger technologies.

DevOps Engineer

Fintonic 2017 - 2020

As part of the DevOps team at a personal finance platform operating across Spain and Latin America, we drove a three-year infrastructure overhaul — migrating from IaaS to Kubernetes, building CI/CD pipelines and IaC tooling, and wiring up observability across the full stack. Production stayed up throughout.

Junior Systems Architect

Kimia 2015 - 2017

First IT role, at a global digital advertising company. Provisioned and managed bare metal Linux servers and AWS cloud infrastructure, built CI/CD pipelines, and wired up monitoring across the platform. The foundation that everything else was built on.
