Izan López Seco — SRE, remote across Europe
Nine years shipping software. Self-taught since 2015, in production since 2017. Whatever language, whatever cloud — hand me the service nobody wants to own and I’ll make it boring again.
01
The route
Site Reliability Engineer, USTSenior in a six-person team. Multi-language microservices on Lambda and ECS, shipped under real deadline pressure. I mentor and onboard the engineers who join, sit on the interview side of the table, and own the pager for what we run.
Cloud Engineer, IntelygenzBuilt BBVA’s authorization platform with a team that owned every step — design, code, testing, deployment and security. Java and Python on AWS, shipped continuously.
Software Engineer, atSistemasStress-tested Inditex’s platforms until they fell over, then helped make them hold. Before that, an incident-management system for Mutua Madrileña. Where backend work turned into infrastructure work for good.
Full-stack developerEveris, Atmira, CINTE Iberia and Alvantia. Banking and insurance work, front and back — where I learned what breaks in production.
The first commitNo degree, no bootcamp. Documentation, side projects, and a great many broken builds.

The craft
Production on-call
I own the pager for what I build. Incidents, post-mortems, and the unglamorous fixes that stop the same page arriving twice.
Faster, safer deploys
Cut deploy time and failure rate on a pipeline running under permanent deadline pressure, without asking the team to slow down.
Grew the team
Mentored and onboarded engineers, set the standards we hold each other to, and interviewed the people who joined us.
Would take a production ticket in
Java · Python · TypeScript · Groovy · Bash
AWS, Kubernetes, Docker, Terraform, Jenkins and GitHub Actions day to day; Spring, Kafka, gRPC, MongoDB and SQL underneath; Grafana and OpenSearch to see what’s happening.
Spanish and English, professionally.
03
For fun
Not a portfolio — these aren’t what you’d hire me for. They’re what I build on weekends, and they’re a fair sample of how I think when nobody is paying me.
mc-server-launcher
Groovy
Configuration and launch tooling for the Minecraft server I run for friends. Small-scale ops with a very demanding user base.
mm-project
JavaScript
A live view of the mods running on that server, so nobody has to ask me what’s installed. Built to answer a question once instead of forever.
rps-fe & rps-be
JavaScript & Java
Rock, paper, scissors split properly across a Java backend and a JS frontend. A silly game used as an excuse to get the seam between them right.
