### Software Engineer @ Codesmith
Jan 2018 – Jan 2019 | Greater Los Angeles Area
• Integrated Redux Form field-level validation to ensure form values inputted by users are logged and persisted for future authentication pre-population of saved forms
• Populated form value options by fetching data from PostgreSQL backend through Redux Thunk middleware to dynamically render field options
• Utilized data visualization library to create React-based key metric dashboards for business intelligence reporting

### Software Engineer @ Reactide
Jan 2018 – Jan 2019
•  Spawned multiple Node.js processes to create React project boilerplate with shell commands while IDE occupied main thread
•  Utilized Electron for ipcRenderer, ipcMain, and mainWindow Event Emitters to control communication between parallel electron instances to enable manipulation of the IDE, users’ file systems, and node child_processes within a desktop app
•  Used Flow parser to create an abstract syntax tree for each of the user’s files to pinpoint React components and construct an object that represents the parent-child relationship of components
•  Formed Regex expressions to pinpoint key/value pairs of the AST to consolidate syntax variations while parsing and lowering computational needs of our algorithm for constructing the component tree
•  Developed a recursive algorithm to parse through a user’s file tree to extract React components and their associated props in order to display component relationship previews while in development mode
•  Utilized Webpack in conjunction with Node child_processes to run a Node live component simulator living in the IDE to increase React component prototyping speed through fast multi-threaded non-blocking execution
•  Integrated Monaco Editor with JSX, CSS, HTML, and JS syntax highlighting/parsing while optimizing existing Monaco editor implementation to utilize a single view with multiple models to save user memory
•  Made a React-based GUI to send consolidated commands to a Node spawned pseudo-terminal for use with the IDE to allow execution of bash or cmd commands natively
•  Integrated React/Redux devtools into live simulation to provide production and development feedback throughout workflow

### Business Analyst @ UST Global
