  I am a member of the Runtime team. A non-exhaustive list of the work I've done during my time at Airkit: • Designed and implemented a log-based, eventually consistent, state-store using Redis and Postgres to process concurrent updates to the state of an Airkit application. Wrote Lua scripts to guarantee operation atomicity on Redis. • Worked on Airscript – the language used to develop distributed apps on the Airkit platform. For instance, I introduced LET...IN syntax to Airscript which allows users to declare local variables (associated Airkit documentation about the syntax is attached)• Developed a type-inference system for Airscript functions to accurately predict argument and return types using a constraint-based algorithm. This gives static-analysis warnings during development, preventing runtime errors due to incompatible types.• Revamped the implementation of AirValue -- an immutable JS library used by Airscript at runtime -- to store metadata along with values.

  • Created a notification service using AWS technologies such as SNS, DynamoDB and Lambda at Amazon Advertising. • Introduced a secondary index on the DynamoDB table used by the service, which lead to a 74% reduction in querying times for non-key attributes, allowing the Lambda to achieve a runtime of 13s. • Used Java 11 to write the core logic of the service and TypeScript to create the infrastructure through the AWS CDK • Created a notification service using AWS technologies such as SNS, DynamoDB and Lambda at Amazon Advertising. • Introduced a secondary index on the DynamoDB table used by the service, which lead to a 74% reduction in querying times for non-key attributes, allowing the Lambda to achieve a runtime of 13s. • Used Java 11 to write the core logic of the service and TypeScript to create the infrastructure through the AWS CDK

  • Effectively collaborated with people from 3 different teams to create a troubleshooting app for an internal Amazon portal to help employees resolve issues regarding the availability of an item on the Amazon retail website. • Made the app interactive by using a question tree to narrow down the possible issues based on user’s responses to ensure their pain-point is addressed as fast as possible • Used React to develop UI for the tool and the Spring MVC Framework for the backend. Extensively tested the application using Java testing libraries such as JUnit and Mockito Show less
