Contributor to https://github.com/yugabyte/yugabyte-db on cluster management (managed)

IoT & Kubernetes SaaS control plane (Karbon Platform Services) architecture and development. Some of my work.

• Control plane in golang

• Auto k8s cluster provisioner on public cloud

• Upgrade systems for IoT edges (patented)

• Trial signups via OAuth2 to give pre-provisioned IoT system to start playing immediately

• Auto scaler for pre-provisioned IoT system

• Serverless service deployment framework

• Event collection and persistence on MongoDB

Cloud services development https://www.cloudera.com/products/altus.html

• Implemented an AWS lambda based Dynamodb incremental backup tool

• Implemented a generic AWS ASG lifecycle listener hook to gracefully shutdown backend services

• Implemented support bundle collection on cluster shutdown using AWS Simple Workflow.

• Reduced the PAYG Billing and Metering processing time from hours to minutes by figuring out bottlenecks in DB calls and optimizing the processing of S3 objects (custom S3 object iterator)

• Owner of Billing & Metering

FVP cluster management server, cloud data collection (call-home) service with MongoDB as the persistence layer.

• Implemented multithreaded concurrent in-order processing of events from thousands of VMs and various memory and speed optimizations in the existing code.

• Implemented a coordinated support bundle collection from all distributed nodes in a cluster.

• Designed and implemented the cloud data collector (call-home) to collect data from customers.

• Implemented a custom transaction library on MongoDB and additional query syntax (JSON based)

E-commerce services, infrastructure

• Worked on the complex discount calculation of items discounted at item or item groups or total price to arrive at a deterministic price for checkout and return.

• Designed and Implemented a hierarchical policy management framework (PMF) to allow policies to be defined at the intersection of nodes from multiple hierarchy trees.

• Designed and Implemented a custom inverse bloom filter to allow false negative with lazy loading because the general caching layer over the DB did not help for cache miss in the PMF.

• Demonstrated PMF on the Walmart Innovation Day.
