Xavier Serrano

Senior engineer focused on high-availability platforms, practical user experiences, and developer tooling that actually ships.

  • Proactive, Product and Platform.
  • I am the Kubernetes guy for product engineers and the React guy for platform engineers.
  • I'm just as comfortable fixing a DNS issue or tweaking website styles as I am improving UX or tackling a world-class problem.
  • I speak to the agents with philosophy and discipline.
  • I'm building up my hardware skills for what's coming next.

Talks & Presentations

Conference talks and meetup presentations on frontend engineering, observability, and engineering culture.

  1. CĂłmo casarse con Next.js

    Alicante FrontendMeetupSpanish
    April 2025

    A candid, behind-the-scenes account of building a full wedding RSVP system with Next.js and Airtable. Goes well beyond a tutorial by showing how a modern full-stack app can tackle real logistics—RSVPs, dietary restrictions, seating charts, companion tracking, and last-minute changes—without any dedicated backend infrastructure. Demonstrates Next.js API routes, server-side rendering, and Airtable as a human-friendly, schema-flexible database that non-engineers can operate. A story of pragmatic tech choices under deadline pressure and genuine emotional stakes.

  2. Believe in Ops | DevOps 101

    Alicante FrontendMeetupSpanish
    June 2023

    A ground-up introduction to DevOps culture and what genuinely separates high-performing engineering teams from struggling ones. Examines the full engineering feedback loop from commit to production and dissects common dysfunction: alert fatigue, broken on-call rotations, fragile deployments, and diffuse ownership. Argues for a culture of awareness, accountability, and shared responsibility—where testing in production is a deliberate practice, not a mistake. Closes with a practical overview of observability foundations, incident response workflows, and disaster recovery thinking as first-class engineering disciplines.

  3. Observability in Frontend: React ❤️ OpenTelemetry

    React AlicanteConferenceEnglish
    September 2022

    A deep dive into bringing production-grade observability to the frontend. Introduces OpenTelemetry—the emerging open standard for distributed tracing, metrics, and logs—and walks through integrating its JavaScript SDK into a React application from scratch. Shows how to instrument user interactions, capture HTTP request spans across service boundaries, and wire the React app into the same observability pipelines used by backend services, enabling genuine end-to-end distributed tracing. Challenges the assumption that observability is a backend concern and makes the case for treating the browser as a first-class node in the trace graph.

  4. React Hooked on a Feeling

    Alicante FrontendMeetupSpanish
    June 2019

    An exploration of React Hooks at the moment they were reshaping the entire ecosystem. Unpacks why hooks were introduced, what fundamental problems they solve over class components, and how to build the right mental model for useState, useEffect, useRef, and custom hooks. Goes beyond the API surface to examine the design philosophy: colocation of logic, composability over inheritance, and the end of lifecycle-driven thinking. Discusses how hooks would—and did—define the future of component-driven development, and why the shift matters even for developers coming from other frameworks.
