About me

About Me

I am a CTO with several years of experience, primarily in e-commerce projects. Previously, I was a consultant and fullstack WordPress and Woocommerce developer, participated in several startups, and founded my own company, which I left when I became a father to have more freedom and spare time :)
With an entrepreneurial gene, I am passionate about the business side, to which I strive to add value with my technical knowledge and experience.

I bring my vision and strategy for e-commerce and digital transformation to companies, based on my extensive experience in business and technology.

I’ve had the pleasure and honor of participating in three startups, from lead developer to technical director / CTO, thanks to my cross-functional vision of the company as an organization.

I love to contribute and share, and I actively participate in the WordPress community as a speaker at meetups, organizer of the WordPress Valencia meetup, organizer of WordCamp Valencia, and translator.

RentalThemes

CTO

Along with Blogestudio, we created the RentalThemes brand, where we developed a WordPress plugin to facilitate online holiday home bookings. This plugin integrated with an external platform that allowed the publication of properties on various marketing portals such as Booking.com, Airbnb, HomeAway, TripAdvisor, among others. My role was to define the scope of the development, select technologies, coordinate the team, and participate in the implementation.

Blogestudio

Colaborador

I’d been collaborating with Blogestudio on implementation and maintenance projects for a long time. They are one of the most renowned companies in the world of WordPress at a national level and have vast experience. Their projects and clients are always significant and technically interesting. Above all, they are great friends.

Stop Murphy S.A.S.

Advisor

StopMurphy is another startup that originated in France. It is a worker training project that solves a significant issue regarding the control and management of the type of training each employee has received. This is vitally important for all aspects related to occupational risks and is highly beneficial for companies with high employee turnover, specialized roles, and seasonality. The project is based on WordPress, and it involved 3D modeling of client facilities and a system for tracking training, control, and statistics.

HipHunters

CTO

I had the pleasure of being part of this startup that emerged from Lanzadera (a Valencian incubator), with a business model of a luxury fashion marketplace. The main technologies we used were NodeJS, MongoDB, and WordPress. We carried out multiple integrations with various systems, and we used scraping techniques with prior consent. Unfortunately, shortly after I left, it had to shut down due to lack of funding. The startup world is not always as glamorous as it is painted.

Ene 2011 - Jun 2014

Chicisimo

Lead developer, UX

Chicisimo was my first startup, a fashion social network, the largest in Europe, where I learned a lot about how this “startup” world works. We were part of it as Onestic, with a relationship as technology partners. It was tough being in a startup while also having an e-commerce services company, but we achieved great things. In addition to a large number of users, visits, and an incredible number of page views, having launched a mobile app that has been recommended by Apple in many countries, the peak moment I experienced at Chicisimo was a collaboration with eBay in which we offered our content in their mobile app, in the fashion inspiration section. I have great memories and experiences from this adventure.

May 2008 - Dec 2013

Onestic

Cofounder

Onestic, an unforgettable experience. A few years ago, several friends and I decided to join together and write our future. We left our jobs and created a web page and application services company. Later, it would become (forgive me for the lack of modesty), the most advanced Magento e-commerce solutions provider company in Spain. It was a pleasure to have been part of the beginning of its history and to have made great friends like my (ex)partners (for me we will always be partners).
