Beltrán Rengifo — Senior Software Engineer
I build software end to end — with a frontend heart.
A full-stack engineer with 14+ years shipping web products — deep in frontend, clean UI and UX; fluent across the stack, from Node and Java to CI/CD.
Available for new roles worldwide since July 2026 — your timing is impeccable.
Experience
2022 — 2026
Mews
Squad Lead — Experience team, Growth tribe
Feb — Jul 2026
Led a cross-functional squad delivering major user-experience improvements, from an entirely new product navigation to the core PMS, to key upgrades to the main assistant search. Planned the work, ran team ceremonies, and mentored junior engineers while remaining the team's main delivery engineer — and introduced AI-assisted workflows and tooling that cut repetitive work and sped the team up.
Tech Lead — Design System team, DX Platform tribe
Jun 2024 — Feb 2026
Set the technical direction for the design system powering a large product's UI — component APIs, tooling and engineering standards — as a formal code-owner. Led delivery of its DataGrid (filtering, URL-synced state, grouping, accessibility), now the default for data-heavy screens, and drove component adoption across our main product, the PMS, and the Events Management System, among others.
Senior Software Engineer — Design System team, DX Platform tribe
Dec 2022 — Jun 2024
Shipped component libraries and frontend tooling for a large React/TypeScript codebase, and contributed to the multi-brand design-tokens pipeline (Figma → Style Dictionary → web and native) — raising UI quality and consistency at scale. Partnered closely with product engineers, offering hands-on support, and with the Platform Productivity team to improve developer experience across the board.
2021 — 2022
Liferay
Senior Software Engineer, Product
Product engineer on Liferay DXP — the enterprise digital-experience platform — building and shipping rich new features, most notably for the 7.4 release, with React, Clay, portlets and a healthy measure of Java. Beyond the code, I helped shape the roadmap with product owners and improve team workflows with project managers.
2020 — 2021
Docline
Frontend Lead↗
Led the frontend of a telemedicine platform, taking its Vue codebase to the next level — component reusability, best practices, and large-scale refactors, including introducing an app-wide shared store as the single source of truth for application state. Reviewed architecture, standardised code reviews, fostered a strong team culture, and improved the existing design system across Vue, TS and SCSS.
2018 — 2021
Minsait · Indra
Product Owner & Engineer — Onesait platform website↗
2020 — 2021
Owned and delivered the main web app promoting Onesait products, bridging engineering and marketing. Led a team of four engineers and one designer, managing multiple stakeholders.
Senior Software Engineer & Consultant — Onesait Design System↗
2018 — 2020
Main delivery engineer on the Vue.js-based design system, and the go-to reference supporting every product engineering team adopting it.
2018 — 2019
Ironhack
Web Development Instructor
Taught intensive full-stack web development bootcamps. Fast-paced and hands-on — and nothing hones your own fundamentals quite like teaching them to others.
2015 — 2018
Tau Design
Web Development Lead
Led a team of up to six developers at a design-led agency — client-facing work, pitching, and mentoring juniors — delivering marketing and corporate sites, e-commerce stores, and a steady stream of microsites for clients like Edelvives, ECAM, Universidad Autónoma, Mapfre and Telefónica. In a studio that lived and breathed design, the bar was pixel-perfect: high-craft UI, rich interactions, and truly responsive layouts, on a jQuery, PHP and WordPress stack with SCSS and Node tooling.
2012 — 2015
AulaCM
Web Developer & WordPress Instructor
Helped build and maintain the company's main site and the client websites delivered by its agency arm — my first taste of agency work and shipping custom WordPress in PHP. Doubled as the in-house WordPress instructor, teaching plugins, themes, styling and the PHP basics that make it all tick — and learning plenty the honest way myself.
2004 — 2012
A previous life
Film & TV Sound Engineer↗
A parallel life in sound, from around 2004 — production and post for film and TV. Two Goyas for documentaries, a Berlinale run after three weeks filming with orphans in Kenya, and a good showing at festivals besides; behind the desk, a Pro Tools wizard and Final Cut obsessive fluent in Avalon compressors, Neve preamps and a wall of top-notch mics. With my friend Iván I built lacasaestudio — still alive and thriving — and the instincts stuck: precision, grace under live pressure, reading a room, and tight teamwork.
Selected side projects
A web app for musicians: record rehearsals, split them into stems, get MIDI and notation, and build gig playlists — with trimming, EQ and MIDI instruments. In private beta.
TypeScript · Python (audio/MIDI) · Docker
The online cake shop for my sister's bakery — a storefront plus a back office to manage products, attributes and orders.
Astro · React · Supabase · Tailwind · Vercel
A Mapbox map of Carabanchel's cultural landmarks in Madrid, built with IED (Instituto Europeo de Diseño) — a Strapi back office with the business logic in Node middleware.
Mapbox · Strapi · Node
A little portfolio for architect friends — a custom back office and a lot of spare-time care.
My private take on Félix Valluguera's paella app and workshop — a rice calculator, evaporation tests and more, as an installable PWA.
