Experience
Internet Of Things Data Management
https://github.com/opendaylight/iotdmCisco has open-source, Internet Of Things Data Management project. While working at Cisco, I managed to solve it's performance problems.
As a back-end database, Cisco's proprietary database was replaced with Cassandra.
Changed project architecture so that everyone could easily plug their preferred database. Even though project was never intended to run in more then one thread, managed to run it on cluster, for that he had to solve problems like tree sharing and appropriate locking mechanisms.
Replaced HTTP protocol, with high performance, fault tolerance framework Kafka.

Object Tracking, Route Authentication, Alerting and Movement Predictive System
http://priorart.ip.com/IPCOM/000245729Researched and created movement prediction system for multiple, distinguishable targets using sparsely distributed sensors. This paper was published on ip.com by Cisco.
Object tracking was occurring in Africa. IOT devices have been connected to the intermediate server using MQTT. Through the low bandwidth internet intermediate server has been uploading the data using Kafka. Finally, data was stored in the cluster of MongoDB.
