This site features cloud infrastructure design for all web properties of the group. The project's scope was migrating from classic hosting to a multi-zone cloud environment. 这个新环境必须具有弹性, able to manage 3Mpv/month, 并且能够在5米(e)内对交通高峰做出反应.g., during F1 events, traffic increases 10 times, and in case of an accident 40 times).

We chose AWS and redesigned apps to take advantage of all AWS components like computational instances, dedicated databases, load balancers, Memcached servers, CDN, and PHP optimizations. Load tests demonstrated good results, with >80% savings on starting costs. Nowadays, the infrastructure is composed of several Amazon EC2 instances and several RDS instances in multi-zone + multi-read replicas. 我们将实例总数增加到200. 该基础设施还利用了Amazon S3和CloudFront.

Android平台多平台移动应用开发成功, iOS, Windows, BlackBerry, and Symbian devices, 为用户提供无缝体验，节省排队时间. 您可以在选定的大学使用Qurami, hospitals, or public offices to get a virtual queue ticket and monitor the queue directly from your smartphone.

Server architecture is based on Silex and communicates with remote Java agents through the XMPP protocol. 服务器提供与移动设备交互的API. We implemented a robust solution on the AWS stack to handle a large number of remote agents (potentially thousands), ensuring scalability, stability, and privacy. Also, we addressed critical management points to support distributed operations across various locations in Italy for Qurami.

这家初创公司从2010年成立到上市，都是我一手促成的, firstly as the CEO and CTO and later delegating the CEO role in order to focus on tech matters. During that time, 我对界面进行了可用性测试, 为应用中使用的技术申请了专利, 并与欧洲主要信用卡处理商达成协议. 该团队研究了市场策略, managed the business budget, 并向许多节目展示了这个想法, contests, investors, etc. As CTO, I coordinated the development of four different apps descending from the various product evolutions. 我们面向Android、iOS和网页开发游戏.

Punctis是一款社交网络应用. Its main purpose is to collect user actions on several websites and assign prizes for those actions. 我来这里是为了创建一个生产基础设施来服务大客户, 比如新闻网站和大品牌.

我设计了他们的基础设施, handling development, testing, 以及具有自动迁移和可伸缩性的生产环境. 这一切都是使用EC2和RDS在AWS上实现的. Since the main load is not the website but the REST API, we decided not to use CloudFront.

Beatpick是一个使用Symphony2开发的web应用程序, 使用Adobe的媒体服务器和媒体播放器. My work consists of three main tasks: changing the app to manage Japanese market differences, 保持原始应用程序的运行, 以及管理到不同版本的自动迁移.

I replaced all proprietary technology from Amazon with open source products (provided and configured by other team members), 确保平台不发生中断. 我还使用EC2将整个应用程序和媒体库迁移到AWS, RDS, S3, 和CloudFront(包括压力测试和故障恢复自动化).

我为电视节目做过几个不同的项目, 包括目前在线使用的付款表格. 我使用Drupal(集成PayPal API)处理用户体验和CMS开发. Some other modules to track referrals and enable external inclusion of the form are also used. 电子卡模块是基于99design上的一个众包竞赛. The registration form is for a national initiative in multiple locations called Walk of Life. 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.

音乐会和活动的票务市场. It's a Symfony 1.4 project that features many external APIs for shipping (UPS), payments (PayPal), and SMS (PROmemo). 它以It - enes -ru的多语言门户为特色. The project is long-term and employs developers from many countries with a very short turnover. 最重要的管理问题是知识转移. 最近我负责基础设施的更新, 将应用从Ubuntu 8迁移到Ubuntu 14, automating deployment, 以及将版本从SVN迁移到Git. 服务器基础设施部分在阿姆斯特丹，部分在巴塞罗那. 它非常小，因为它是由一个web服务器和一个数据库组成的.
