I was part of CSP (Cyber Security Practice) team. I directly reported to Global Head of CSP to research the ongoing data engineering project. My goal was to test feasibility of creating our own SIEM (Security Incident and Event Management) tool by creating PoC (Proof of Concept), prototypes and MVPs.

Led the development of an in-house SIEM tool, working directly with the global head of cybersecurity and utilizing big-data tools such as Apache Kafka, Storm, and Metron.

Deployed a Hadoop cluster on AWS, including tools such as ZooKeeper, Ambari, Elasticsearch, Kibana, and HBase. Benchmarked this environment with various configurations.

Utilized Java to deploy a Storm topology to filter, enrich, and index logs on an AWS cluster.

Created demo dashboards in Kibana to demonstrate an organization's security health.

Designed a problem for a global coding contest for students (CodeVita) and received multiple special achievement awards for top performance in internal coding competitions.

Earned a Google Certified Data Engineer certification and gained in-depth knowledge of Google Cloud.

Developed a system for delivering and validating high-volume one-time passwords (OTPs).

Researched and benchmarked commercial SIEM tool DNIF, collaborating with their engineering team to better understand the product.

TCS landed some clients due to my PoC efforts.

CSP team gained confidence on their ability to develop in-house SIEM tool and market it.
