Technical Leader I (2017 - 2019)
Technical Leader II (2019 - 2021)
Summary: After Cisco acquired Observable Networks, I became the lead engineer for a team of 10 software developers and advanced support engineers working on all aspects of Stealthwatch Cloud, Security Analytics and Logging, and related services.
Designed and implemented large-scale data processing pipelines (primarily in AWS) for network security monitoring applications (primarily written in Python)
Developed integrations with AWS, Azure, GCP, Kubernetes, and various Cisco products
Worked with product management and sales teams to scope business requirements and develop product roadmaps
Acted as engineering liaison to customer support, writing up enhancement requests and prioritizing user-reported bugs
Mentored junior engineers and interns and managed outside contractors
Sample project: Cloud-scale event ingestion pipeline.
Worked with product management from the project’s inception to understand business requirements and customer use cases, develop a scope of work and schedule, and create proof-of-concept solutions.
Designed and implemented a data pipeline that supports: live streaming of incoming events, flexible querying of previously collected data, and multiple front ends (command line, API, web browser)
Technical highlights: 100% serverless. Uses AWS Kinesis, Firehose, Lambda, API Gateway, DynamoDB, CloudWatch Metrics, SQS, and S3.
Operational highlights: Inexpensive to operate (no permanently-running servers), scales up and down automatically with system load (using standard AWS primitives)
