Chief Architect, VP and Head of Architecture

• Lead an Architecture Office and/or Competency Center, to bring much needed cultural change, cross-departmental collaboration and engineering discipline in the organization. Responsible for 3-year Technical Roadmap and Quarterly Architectural Runway.As an IBM Watson Executive Architect, work as a founding member of Architecture Guild responsible for guiding the development of IBM’s next generation Watson Cloud, Data and AI/Cognitive platforms; that will replace Classic Bluemix/SoftLayer/Watson platforms.
• Re-architecting TWC Web Platform to be CMS Agnostic and composable as a set of configurable blocks of Isomorphic Micro Services; using React and Angular 2.0 on node.js. This will help TWC address global markets in places with constrained networks (2G and below) and devices with limited compute. In addition, this will also setup TWC to address IOT devices and Home/Automobile Automation.
• Developed TWC’s Engineering Handbook including Guiding Principles, Key Reference Architecture Patterns, Common Rules and Standards for entire technical organization including both B2B and B2C. Evangelized the engineering handbook extensively with all technology and product teams to build consensus and help build a disciplined but fast moving engineering culture with minimal bureaucracy. Used this process to build consensus around the concept of Architecture Competency Center.
• Oversaw the architecture of second generation 100% Cloud based but vendor agnostic data platform (SUN v2.0); capable of ingesting 400+ TB of raw compressed data daily from 800 or more partners and serving 50+ Billion API requests/day; with multi region support and 99.99% up time. The average response time for APIs is 15ms not including Internet network latency; and cache hit rate of ~93%. The architecture includes following component layers:
• API Gateway/Router/Controller including API Key driven auth., security, metering and throttling.
• Micro Services Polyglot serving Restful API for both Ingest (IAPI) and Output (OAPI).
• AWS Implementation of 4 Region (3 Availability Zones each) AWS deployment with 6000+ instances and/or Kubernetes Docker Containers.
• Petabyte Scale (>5 PB) Storage Polyglot including Cassandra, Hadoop, S3 Data Lake, Redis, Mongo and Riak.
• Active Queue Exchange including Rabbit MQ, Apache Kafka and Amazon SQS.
• Multi-Tier Caching at Edge (Akamai), Origin (Varnish) and App instances (Redis / AWS ElastiCache). Also, incorporates Edge Computing via Akamai ESI (Edge Side Includes). Total Edge hits exceed Trillions per month.
• Network Architecture using Akamai GTM, NS1, DynDNS and Route53; with support for multiple CDN providers.
• Data Lake and Analytics utilizing Raw and Parquet storage on S3, AWS EMR, Cassandra, Hadoop, Apache Spark, IBM Streams, Informatica, Redshift, Qlik Sense and Qlik View.
• Data Ingest Polyglot including creation of custom ingestion pipelines utilizing patterns like IBM Streams, Functional Ingest (Lambda/Whisk), Micro DPE (Data Processing Engine) and ISO (Input / Output Micro Services).
• Evangelized SUN architecture blueprint both internally and externally including presentation at IBM Watson Blueprint Talks and AWS Re/invent. Was also featured in Computer World article and interview on TWC Cloud Migration journey.
