Architected Node.js/Express server, making use of Node’s asynchronous non-blocking IO; designed controllers with middleware design pattern for modularized code and language uniformity between client and server.

Implemented Jest and Enzyme to follow test-driven development to promote code integrity and minimize future costs by ensuring reliable product application functionality.

Utilized Vue Test Utils API to expand client interface with unit-test generators, improving development process of Vue components with the abstraction of clean, semantic, and easily exportable test files.

Updated React components to TypeScript to minimize runtime errors and enhance codebase readability.

Refactored legacy codebase built with Node.js runtime (in Electron) by diagnosing and debugging errors that occurred within the application, reducing total overall issues to achieve better product stability.

Employed non-relational database (MongoDB) to store encrypted user information, incorporating a flexible and dynamic schema; leveraged Mongoose to write code that would retrieve, write, and update the stored data.

Incorporated Passport’s flexible modular design to integrate OAuth capability into product, and allow the user to authentically login via Github, improving UI experience by preventing repeat data entry required from user.

Product developed under tech accelerator OS Labs (opensourcelabs.io)

Employed PostgreSQL to chart a relational database schema, ensuring ACID compliance and enabling the extraction of persisted data for one-to-one and one-to-many relationships among the stored tables.

Incorporated Mapbox API to render an interactive geographical map by enabling custom user location pins to collect precise geotagging metadata, allowing users to report persisted location specific incidents.

Engineered Node.js/Express server backend to create flexible endpoint routes and error handling, improving efficiency and productivity by allowing for knowledge and code sharing within JavaScript centric team.
