• Worked on sql projection-pushdown optimizations on large scale query optimization.

• Spearheaded the migration of the open-source project Oppia from Python 2 to 3. Project can be found here: github.com/oppia/oppia

• Replaced backend library usage of unsupported Google App Engine Python 2 APIs with third party libraries (i.e data caching, images, ndb storage, WSGI backend framework, etc.) without modifying the developer experience or the user-facing APIs.

• My work can be found under the user kevjumba PRs at github.com/oppia/oppia.

• Developed a recursive program for serialization of nested protobuf objects for use in gRPC job metadata transmission using Java reflection.

• Compared different serialization libraries(i.e protostuff and protobuf-runtime) using Jenkins Stress Testing and Wavefront metrics.

• Optimized serialization speeds and improved stable serialization CPU time by 25%.

• Wrote the file input and errors, warnings, and external messages components for the Turbotax design system library using React.js and Typescript. Virtually all errors and warnings/ file input elements in Turbotax will use my UI components

• Worked with Fuego-Tools to add accessibility and ease-of-use features to the preview nav bar using Java and React.js.

Added a widget to developer chrome extension to track Turbotax web-flows and manage tools accessibility based on flow content.

• Created a modular Typescript component that will be used in all Turbotax error fields. This Typescript component reads json and schema and automatically renders errors and warnings to fit the Turbotax page environment Updated the TurboTax web player asset accordingly so every Turbotax message(errors, warnings, notifications) can auto-update with changes to the component.

• Worked with Fuego-Tools and Interview/Formset Service to add features to the preview nav bar using Java and React.js, the preview nav bar displays certain preview elements for the topic parameters, processes it in the backend, and renders the preview in the nav bar

Interfaced with Java backend and React.js front end to add to the Fuego Tools GUI that generates json elements. These elements tell Fuego player how to render a Turbotax topic page.

• Worked on the Fuego Dev-Tools chrome web extension using Vue.js and React.js to add a widget to track Turbotax web flows(a DFA graph). The extension displays transitions to states that are not Fuego team specific and also hides Fuego-specific tools in that event.
