Wurl (Applovin)

Positions:

  • Technical Solutions Architect (2021 - present)

Summary: Wurl provides various services for streaming TV platforms and content publishers. I work on projects in a few different areas, particularly the video delivery pipeline and automation.

  • Designed and implemented (in Python) a VOD-to-linear playout pipeline with several advanced features, including DPI and dynamic overlays. Technologies: AWS Lambda, MediaLive, MediaPackage, GraphQL, HLS and DASH.

  • Designed and implemented (in Python) a service for inserting live events into video streams with support for HLS, DASH, RTMP, and Zixi inputs. Technologies: AWS Lambda, API Gateway, MediaLive, MediaConnect.

  • Wrote a full-featured automation package (in Python) to speed up the channel launch and reduce errors. Technologies: AWS Lambda, S3, and MediaTailor, SpringServe, Serverless Framework.

Cisco Systems

Positions:

  • 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)
