The most amazing...
...project I've taken on was rewriting an internal, back-end app at WillowTree in TypeScript from Vanilla JS with Babel.
Work Experience
Staff Software Engineer
WillowTree
- Joined a new team and quickly noticed that the team was writing E2E tests that should have been unit tests. Helped restructure the automation test suite to rely more on unit testing rather than the more fragile and flaky E2E tests.
- Developed several patterns and/or helper functions for the development team at large to use to make their lives quicker and easier.
- Debugged several production issues, one of which was blocking a big push. Solved this particular bug in time for a big push.
- Ensured best practices were being followed throughout the app at large.
- Managed the CI/CD pipeline for the website for a large timeshare company.
- Assisted in creating new processes for a large timeshare company that allowed their customers to sign up for vacations and stays that were only possible over the phone previously.
- Mentored younger developers. Helped take one from being put onto a performance plan to getting them back on track. Taught another component-based frameworks as they only had previous experience with jQuery.
- Rewrote an internal server app from the ground up. Initially written in JavaScript and Babel, I figured out types as I went and converted it to a TypeScript Express.js server. Reworked the entire CI/CD pipeline to properly deploy the new app.
- Expanded on a number of machine learning professional development projects using TensorFlow to train various models.
- Spun up and deployed several web apps from scratch for professional development projects, including one that implemented a homegrown, secure sign-up/login process that utilized passport and Express.js.
Web Developer
Contract work
- Worked with a financial advisor to build them a web app to help with their business.
- Spun up a front-end with React, TypeScript, and Redux. Deployed it via GCP's App Engine.
- Spun up an Express.js API with TypeScript. Deployed it via GCP's App Engine.
- GCP's Datastore was used as the API's NoSQL solution.
Web Developer
Dude Solutions
- Worked with my team and our PO to design and then implement the structure of several website components using JavaScript on an AngularJS framework. Karma was used for unit tests.
- Worked with the QA Engineers on the squad to build out UI/E2E testing for each story.
- Helped train several developers. Most were junior devs, but one was a senior dev who hadn't used AngularJS before.
- Focused on the entire technology group (6 other teams) by attending Front-End Chapter meetings and helping flesh out the Front-End Chapter's backlog.
- Helped out people on other squads when they posted in group chat for help. Contributed to code quality by reviewing others' code and making comments or suggestions where necessary.
- Heavily involved in and passionate about recruiting efforts and the interview process. Ran technical interviews with other developers, attended a career fair, and evaluated interviewees' code.
Web Developer
ReverbNation
- Worked with Ruby on Rails, Foundation, jQuery, and Angular on a number of web services offered by ReverbNation.
- Helped rewrite our artist profiles in AngularJS (from jQuery) with a new, responsive UI.
- Took on tickets as an individual contributor to help complete our two-week sprints.
Manual QA
ReverbNation
- Performed manual web testing in a weekly scrum environment, with some automation thrown in using Ruby and Selenium.
- Tested Musician Pages, a brand new account type on reverbnation.com for their release.
- Worked on updating a process by which ReverbNation users could add a personalized mobile app to the App Store, which included fully automating some work on Apple's iTunes Connect site using Ruby and Watir.
