Onwhyon

Applications Architect • Nov, 2014 — Jun, 2015

Java Architect, Indicex Project Bankia Indicex. Development of a self-assessment tool of web pages that analyses the level of digitalization through 8 behaviour areas. The final aim is the generation of a report which details the digitalization level of a web page taking areas as SEO Positioning, Usability Contents, Digital Marketing, Social Networking, Web Analytics, E-Commerce and Mobility.

This project was developed using spring-framework 4.1, spring-data, JPA, spring-mvc, restful services, AngularJS 1.3, bootstrap, maven 3.0, MySQL, etc. The project was divided into three distinct phases, On phase 1 was implemented with the API crawler4j to obtain and download the web page code. This API obtains the links and depth level of a web page and through regular expressions, it is possible to filter and get relevant information about social networks, contacts, usability level, speed load, headers, W3C validation, server location, sitemaps, robots, backlinks, analytics integration, AdWords, mobile subdomain, HTML tags, contents length, keywords, CSS content, etc.

On phase 2 was developed several APIs of social network and other functionalities, Facebook Google plus, Google Translate, Instagram, Klout, PageRank, Page Speed, SEMrush, Twitter, W3C, YouTube. At this stage and with the information obtained on Phase 1 we proceed through a pool of threads to obtain the relevant information with parallel tasks.

On phase 3 a web form is presented to the end-user to complete the analysis and it is presented a report. In this report you can get the notes of each measurement area. Working over Scrum methodology, doing daily sprint, sprint reviews, sprint and product backlog, user stories and methods of measurement of priority and importance of each user story.
