Since February 2014, I am a PhD student at the Systems Group at ETH Zurich under the supervision of Prof. Dr. Donald Kossmann.

My field of research is in real-time data warehouseing. I am currently working on the READY project which goal is to explore trade-offs between satisfying multiple users data requirements in a cost effective way but with a reasonable time to market. My interests are around distributed systems, stream processing and databases.

I also contribute to different open source projects, specifically in the Apache Software Foundation.

• Apache Gora: It is an in-memory processing framework which abstract different NoSQL data model into a simple key-value one.

• Apache Samza: It is the streaming transformation platform using Apache Kafka as its main transportation layer.

• Apache Nutch: It is a distributed web crawler leveraring Hadoop for spawning tasks. It mainly does wide crawls but it is being enhanced to provide more vertical crawls.

• Apache Giraph: It is an iterative graph processing system built for high scalability.
