[en] In this End-of-Degree Project it is analyzed with detail the entire process of development of a web application which is custom made for a real client. The process ranges from the very first meeting with the clients - where they expose the necessities they have for they business and when the process starts to be routed-, going through the different phases of design and codification, finalizing with the tests and closing the contract. The client owns a real estate business, focused on the sale of luxury homes. Their business model was the traditional. They had not jumped into the ICTs until the moment, or at least not the way they desired. They came to our enterprise with an idea which was simple although not easy: creating a luxury real estate portal. This portal would be the last step in the path initiated with this project. The initial phase, which is treated in this project, consists on creating a platform for the clients' enterprise to both advertise and sell their properties. The idea of creating a luxury real estate portal has proven to be, a priori, very feasible. The preexistent luxury real estate platforms were analyzed, and it turned out that there existed quite a powerful market niche. The strategy established to reach the creation of this portal is divided into three phases: The initial phase consists on developing the basis application for our clients -where they can upload their own houses- plus accomplishing their design, efficiency and user experience standards. In the following phase, which extends to more than a year, we will focus on the SEO and the SEM, their social networks and the dissemination. Once the website starts giving benefits by increasing the number of properties our client sells, and once the positioning is noticeable, it is possible to initiate the final phase. Once the application has reached a positioning enough to stand out from the rest of platforms, at least at a national level, the possibility of advertising on the website in exchange of a little percentage of the benefit will be given to third-party firms. A good development is crucial to create some powerful foundations above which start building the rest of the project. The SEO and the SEM are another fundamental factor to reach the final goal, and although it is not an object of analysis in this project, some basic related notions are addressed given that they affect the development of the first phase. Having said all this, this End-of-Degree project also has an utility beyond the success of a business project. The concepts and ideas here exposed could be useful for anyone who is willing to start a web project, without the availability of resources that a big enterprise can offer, being then able to compete with them. The chosen technology to develop this project reduces to the maximum the loads in terms of time, economic resources and working personal, allowing the creation of applications of equal or better quality than those developed by using traditional technology.

[es] En este Trabajo Fin de Grado se analiza detalladamente el proceso íntegro del desarrollo de una aplicación web a medida para un cliente real. El proceso abarca desde la primera reunión con el cliente, donde estos exponen las necesidades que tiene para su negocio y donde se comienza a encaminar el proyecto, pasando por las fases de diseño y codificación, para finalizar con las pruebas finales por parte del cliente e inicio del mantenimiento. El cliente tiene un negocio inmobiliario, centrado en la venta de casas de lujo. Su modelo de negocio era el tradicional. No habían dado el salto a las TIC. Acudieron a nuestra empresa con una idea sencilla, pero nada fácil de llevar a cabo, crear un portal inmobiliario de casas de lujo. Pero éste se conseguirá en la fase final del proyecto. La fase inicial, la cual se aborda en este TFG, consiste en crear una plataforma que sirva a la empresa del cliente para anunciar y vender sus propias casas. La idea final de crear un portal de venta de casa de lujo resultó ser muy factible. Se han analizado las paginas ya existentes de venta de inmuebles de lujo y resulta que hay un nicho de mercado bastante potente. La estrategia que se ha establecido para llegar a crear dicho por tal se divide en tres fases. La fase inicial consiste en desarrollar la aplicación base para nuestro cliente, donde ellos puedan subir sus propias casas y que cumpla con los estándares de diseño, eficiencia y user experience actuales. En la siguiente fase, que se prolongara más de un año, nos centraremos en el SEO y el SEM, así como en las redes sociales y la difusión. Una vez el sitio web comience a dar beneficios aumentando el número de inmuebles que vende el cliente, y el posicionamiento sea notable, se podrá iniciar la fase final. Una vez demostrado el rendimiento y el posicionamiento de la aplicación, se comenzarán a anunciar inmuebles de terceros, garantizando la venta de estos a cambio de un porcentaje del beneficio. La fase de desarrollo es crucial para crear unos cimientos fuertes sobre los que empezar a construir el resto del proyecto. El SEO y el SEM son otro factor crucial para alcanzar la meta final, y aunque no es objeto de análisis en este TFG, si se abordaran ciertas cosas básicas que afectan al desarrollo de la primera fase.
