  • Company description: SR Enables public companies to track their investors’ behaviors and trends and use those insights to engage investors across marketing channels.
  • Period:November 2015 - August 2017
  • Activities: Working on SR was both fun a challenging. When I started, the company’s Ad exchange backend was the typical LAMP stack with a lot of legacy code on stored procedures and PHP/CodeIgniter code. Deployment process was completely manual and error prone.

    My first assignment was to streamline their somehow complex onboarding process, I wrote the backend using stored procedures and tested them using PHPUnit and a MySQL server running on a ramdisk.

    Their Real Time Bidding system relied on a proprietary algorithm written in C++. The developer had never worked on Linux before, so I helped him by configuring a proper sandbox server and wrote a tool that would pull the latest changes from SVN/Git, compile the code and restart the web server with a webhook or with the click of a button.

    At the end of my time on SR/SRAX the new onboarding process was finished, we had already integrated several ad exchanges into our backend (a huge milestone), the team migrated from SVN to Git, we started to write tests with PHPUnit and Selenium and the developer’s development enviroment was now semi automated using a customized version of Puphpet, (code named Arale) and the whole team was already using Agile methodologies. Besides the developer role, I also enjoyed administering some of Linux servers with Puppet and staring to New Relics graphs.

I was in charge of monitoring all the changes pushed by the developers; Our Database load had high concurrency and I had to look for naive queries that otherwise would trash the DB server. Also since database sizes typically exceeded Terabytes, we had to be a bit extra careful for backups. Some of the SQL Servers had HA configurations like replicas and Always On. Also, I had the chance to work on internal tools using ASP .NET MVC., AWS S3, VMWare, Python and RabbitMQ.
