Using Ruby I've had the opportunity to participate in a wide range of projects: from working with the CERN to building a financial calculator for energy related commodities or use Cassandra and Kafka for processing cybersecurity related information.
My latest project: building tools for a global Customer Support.
I joined Klarna in February 2015 to build the customer support web interface. We were a team of three developers plus a designer and grew up to 10 people before the end of the year. Our task was to develop an application to fetch and merge information from several microservices and then present available actions to the Customer Support advisor.
- Elasticsearch: 10M documents, aprox 10Gb of data (by March 2016).
- Test suite: 99,7% coverage, 6 minutes to run.
- Uptime: 100% during working hours.
