该站点为集团的所有web属性提供云基础设施设计. 该项目的范围是从传统的托管迁移到多区域云环境. This new environment had to be resilient, able to manage 3Mpv/month, and able to react to traffic peaks in less than 5m (e.g.在F1赛事期间，交通流量增加10倍，在发生事故时，交通流量增加40倍)。.

我们选择了AWS，并重新设计了应用程序，以利用AWS的所有组件，如计算实例, dedicated databases, load balancers, Memcached servers, CDN, and PHP optimizations. Load tests demonstrated good results, with >80% savings on starting costs. Nowadays, 基础设施由多个Amazon EC2实例和多个RDS实例组成，这些实例位于多区域+多读副本中. We increased the total number of instances to 200. The infrastructure also takes advantage of Amazon S3 and CloudFront.

The multi-platform mobile app was successfully developed for Android, iOS, Windows, BlackBerry, and Symbian devices, providing users with a seamless experience to save queuing time. You can use Qurami in selected universities, hospitals, 或者在公共办公室买一张虚拟排队票，直接用智能手机监控排队情况.

服务器架构基于Silex，并通过XMPP协议与远程Java代理进行通信. The server provides an API to interact with mobile devices. 我们在AWS堆栈上实现了一个健壮的解决方案来处理大量的远程代理(可能有数千个), ensuring scalability, stability, and privacy. Also, 我们解决了关键的管理点，以支持Qurami在意大利不同地点的分布式运营.

I grew this startup from its 2010 inception until its market launch, 首先担任首席执行官和首席技术官，后来委派首席执行官的角色，以便专注于技术事务. During that time, I performed usability tests on the interface, filed a patent for a technology used in the app, and struck deals with major European credit card processors. The team studied market strategies, managed the business budget, and presented the idea to many shows, contests, investors, etc. As CTO, 我协调了四个不同的应用程序的开发，这些应用程序来自不同的产品演变. We developed for Android, iOS, and the web.

Punctis is a web app for social engagement. 它的主要目的是收集用户在几个网站上的行为，并为这些行为分配奖励. I came in to create a production infrastructure to serve big customers, such as news websites and big brands.

I designed their infrastructure, handling development, testing, and production environments with automated migrations and scalability. It was all implemented on AWS using EC2 and RDS. 因为主要的负载不是网站而是REST API，所以我们决定不使用CloudFront.

Beatpick is a web app developed in Symphony2, making use of a media server and media player from Adobe. 我的工作包括三个主要任务:修改应用程序以管理日本市场的差异, keeping the original app working, and managing automated migrations to different versions.

我用开源产品取代了亚马逊的所有专有技术(由其他团队成员提供和配置), ensuring no disruption happened in the platform. I also migrated the whole application and media library to AWS using EC2, RDS, S3, and CloudFront (including stress test and automation for fail recovery).

I worked on several different projects for Telethon, including the payment form currently in use online. I handled UX and CMS development using Drupal, the integrating PayPal API. 还使用了其他一些模块来跟踪引用并启用表单的外部包含. The electronic card module was based on a crowdsourced contest on 99design. 这张登记表是为在多个地点开展的一项名为“生活之路”的全国性倡议而准备的. The project was simple, but the timeframe was very short; I had five days in total and managed it while working with an offshore development team.

A ticket marketplace for concerts and events. It's a Symfony 1.4个具有许多外部api的项目，用于运输(UPS)、支付(PayPal)和短信(PROmemo). It features a multilingual portal in it-en-es-ru. 该项目是长期的，雇用了来自许多国家的开发人员，周转时间很短. The most important issue to manage is the knowledge transfer. Recently I managed the infrastructure renewal, migrating the app from Ubuntu 8 to Ubuntu 14, automating deployment, and migrating versioning from SVN to Git. The server infrastructure is partly in Amsterdam and partly in Barcelona. It's pretty small as it is composed of one web server and one database.
