The ABot 5G core is a black box with respect to gNodeB. The 5G lab will facilitate UEs (handsets) to test various applications (like drone, camera etc) via the third party gNodeB and the ABot core black box.ABot will allow standard 3GPP procedures. It has the intelligence to handle any scenarios which might arise due to malfunction of any of the UEs which may send any unwanted and unordered packetsequences via gNodeB to the 5G core. ABot also has the ability to enhance itself for such malfunctions that might appear for a few selected 3GPP procedures such as registration, pdu session etc.• Driving development of ABot 5G core, a black box system for gNodeB, facilitating testing of various applications via third-party gNodeB and the ABot core black box.• Establishing 5G lab for UEs (handsets) to test applications like drones and cameras using third-party gNodeB and ABot core.• Enhancing ABot's ability to self-improve during malfunctions for selected 3GPP procedures such as registration & PDU session.• Implementing ABot with capability to handle standard 3GPP procedures and managing scenarios arising from UE malfunctions, ensuring proper handling of unwanted and unordered packet sequences via gNodeB to the 5G core.• Architecting the co-ordination manager, responsible for managing the flow between gNodeB and NFs (Network Functions).• Design and implement connections to remote nodes using SSH and TELNET.• Designing and implementing log collection and parsing for analytics purposes.Environment: Python, BDD (Behave library), RabbitMQ, and MongoDB, Docker, Kubernetes.

NSI (Network Security Intelligence)Enterprise level network intrusion detection system. It allows real time threat detection against all types of known attacks viz. flood detection, worm detection, host scan, port scan, long lived sessions and others. It captures and analyzes flows from routers to detect threats and provide network visibility. There is an extensive UI and reporting mechanism which allows monitoring and auditing the network. • Architected reporting and the dashboard.• UI development and maintenance of the product.• Architected and implemented Python based daemons.• Developed APIs for delivering intrusion reports for customer consumption.• Worked on customer defects, ensuring a high level of customer satisfaction.Python, PostgreSQL, Flask, JavaScript, jQuery, CherrypyScreensaver ApplicationEnterprise product to offer workplace clients an employee screensaver application that runs on employee computers. This screensaver would run on employee computers so when their computer goes into the screensaver mode, this application would cycle through internal content and other various data-based contents. The client’s IT department could deploy and manage, and their internal team could update the content that would be played by a video player embedded in the screensaver application.• Designed and architected the product.• Development of API services, caching mechanism and queuing of data.• Worked on migration to AWS cloud.
