Experience

Hewlett Packard

Information Systems Architect • Jun, 2017 — Present

Led the move of the organization into adopting a cloud-first approach that earned top billing for being Well-Architected. Led the design, implementation, and production run of a greenfield manufacturing data pipeline on the cloud – a first in the organization. This led to near real-time acquisition of manufacturing data to analytical insights using a serverless, scalable architecture. This was recognized across the company as a success and featured in AWS’s This is my Architecture series as well as the World Economic Forum’s Manufacturing Lighthouse Network.

Core Skills:

  • Overall AWS architecture specs, Lambda, DynamoDB, Kinesis, EC2, RDS, ElasticSearch, CDK etc.
More Details..

Worked with the business in understanding needs and helping formulate relevant Business Architecture artifacts the that led to establishing clear design goals and targets. In the initial phases, I led the development in working out patterns the teams would need to implement; small proof-of-concepts. Laid down overall principles to be followed in developing such a pipeline and the DevOps model to be followed. In doing so, I had to write some of the core parts of the pipeline and therefore am intimately familiar with said architecture.

Have hands-on experience in AWS Lambda, DynamoDB, Kinesis, IAM, AWS Batch, Glue, ElasticSearch, RDS, EC2, DMS, ECS, CodeDeploy etc.
