Senior software& DevOps engineer

A decade building web, mobile and desktop applications — and the cloud-native infrastructure they run on. I take products from an empty repository to production, and I keep them there.

Valencia, Spain

I build products end to end — React and Rust clients, Node and NestJS services on PostgreSQL and MongoDB, and the Kubernetes, Terraform and CI/CD they run on. Four of them went from an empty repository to production, one of those solo as co-founder. Another was a 268k-line legacy platform I moved onto a micro-frontend architecture without stopping delivery.

02 · Capabilities

Four practices

01

Product frontends

React, React Router 7 and Remix applications with server-side rendering, complex state in Redux and XState, realtime updates over WebSockets and Server-Sent Events.

02

Mobile & desktop apps

Shared codebases rather than one per platform — React Native for iOS and Android, Rust and Dioxus for desktop and mobile from a single source tree, Qt and QML for native desktop.

03

APIs & platforms from scratch

Node.js, NestJS and Express services over PostgreSQL, MongoDB, Redis and Elasticsearch — CQRS where it earns its keep, built test-first and documented for handover.

04

DevOps & infrastructure

GitOps pipelines and CI/CD, Docker Swarm and Kubernetes with Kustomize, Terraform on AWS and Proxmox, observability on Grafana, Loki, Tempo and Prometheus.

Jan 2024 — Apr 2026

Qollabi

Senior Software Developer & DevOps Engineer

Built Qollabi 2.0, the ground-up TypeScript rewrite of the platform — Remix and Bun workspaces, CQRS and PostgreSQL row-level security for multi-tenancy across seven deployables.
Introduced a micro-frontend architecture into the legacy platform — a React 18 Module Federation remote consumed at runtime by the React 16 host, so both codebases could ship independently.
Maintained and extended the legacy platform: 268k lines of PHP behind a GraphQL API, with a React 16 SPA on top.
Built a Server-Sent Events client on PostgreSQL's LISTEN/NOTIFY, so the apps push updates without adding a broker.
Built the Docker-based development environment and the UAT and production deployment pipelines, including per-branch ephemeral environments with their own database and Keycloak realm.
Maintained the Terraform codebase and the Docker Swarm cluster, owned the AWS footprint — Route 53, RDS, Amazon MQ, S3 and IAM — and set up the VPN and reverse tunnel used for development access.
Developed AWS Lambda functions and Activepieces automation infrastructure, and wrote the Salesforce data migration scripts used to onboard clients.

Jun 2020 — Dec 2023

HolaPlace

Senior Software Developer

Built holaplace.com from scratch with a six-person team — 399 REST endpoints on NestJS and MongoDB, seven Socket.IO gateways and three AWS environments in Terraform.
Developed the React SPA — Redux and XState for the booking and checkout flows, TanStack Query for server state, Socket.IO for chat, notifications and calendar sync.
Implemented the Stripe Connect money flow end to end: deposits, holds, split charges, transfers, payouts, claims and refunds, with separate platform and connect webhook processors.
Built the backend services on NestJS and Express over MongoDB, Elasticsearch, Redis and AWS S3.
Containerized the stack with Docker and Docker Compose, with LocalStack standing in for AWS locally.
Worked test-first with Jest across unit, integration and end-to-end suites.
Automated deployments with Terraform across dev, stage and production, and reviewed code across the team.

Nov 2019 — Jun 2020
