  Google Summer of Code

  May 2019 - Aug 2019

  Software Engineer

  Developing an automated code generation system for TensorFlow implementations of RNN and ML algorithms in Python, enhancing its functionality by integrating preprocessing options and generating the corresponding code and designing a user-friendly dashboard for ‘Tensormap’, enabling users to visually construct machine learning algorithms, thus empowering users to reverse engineer a visual layout into a TensorFlow implementation with minimal background knowledge.

  Software Engineer

  Integrating the 'group by' clause into the Ballerina language by crafting efficient syntax tree node structures and parser error handling sequences, along with the integration of essential semantic and type checking logic up to the desugaring phase with comprehensive parser and compiler testing enabling programmers to organize input data using 'grouping-keys' within Ballerina's 'query expressions'.Devoting considerable effort to align XML behavior with the Ballerina language specification, exemplified by the introduction of the 'XML sequence' concept which involved refining parser syntax trees, error handling sequences, semantic logic, and desugaring, as well as leveraging the ASM library for BIR generation, facilitating the resolution of inconsistencies in 'XML subtype' behavior within the language. Successfully addressing a range of such XML-related issues led to assuming ownership of the XML domain within the Ballerina ecosystem and providing active support to colleagues facing XML-related challenges.Rectifying discrepancies in integer behaviour by strategic repositioning of specific logic into better suited compiler phases and resolving challenges concerning union type checking of integer subtypes which consequently resolved a substantial number of integer-related issues within Ballerina ensuring overall smoothness of integer operations.
