Soft Skills Developed:

• Mentored interns and onboarded new staff members.
• Spearheaded the tool development team.
• Collaborated with the team to elevate:
  • Workflow efficiency.
  • Code quality, readability, maintainability, performance, security, scalability, testability, reusability, extensibility, modularity, and portability.
• Actively communicated ideas, progress, challenges, and solutions to team members, ensuring feedback was timely, constructive, and delivered in a positive manner.

Technical Accomplishments:

• Developed an Angular/Ionic fitness app with Capacitor for iOS/Android (you can see it in this LinkedIn post), showcasing a custom design for swift exercise retrieval and ASENSEI SDK - (the SDK to capture, correct and coach human movement). Notable features include:
  • Implementation of the Figma design within 2 weeks, encompassing app architecture and ASENSEI SDK integration.
  • Video, image, and file streaming from Dropbox.
  • Served as a foundation for the second iteration of the ASENSEI SDK.
  • Acts as a daily-use demo for company employees to build and test content and a testament to potential clients, such as Powerblock (press release here), AMP (press release here) and many more (full list here).
• Engineered a subsequent Angular/Ionic fitness app highlighting the second iteration of the ASENSEI SDK. Angular/Ionic app fitness app which you can see it in these LinkedIn posts: here, here, here, here)
• Crafted a StencilJS web component that melds Three.js graphics, quaternion math, and RxJS, and is automatically shipped as an npm package via semantic release.
• Constructed an Angular/Ionic content-building tool that employs the aforementioned web component. This tool is a daily essential for two full-time employees.
• Innovated a new version of the proprietary markup language and its accompanying content-building tool, built with TypeScript and Node.js. This innovation led to a development time savings of approximately 10 to 12 months to date.
• Designed a VS Code extension enhancing intelli-sense capabilities for the in-house markup language.
• Transitioned projects to an Nx workspace and introduced reusable GitHub workflows. These encompass tasks such as Docker image building for Angular apps, testing, linting, and more. For an in-depth look, see my Medium article: Optimize Your Angular Application Deployment with Multi-Stage Dockerfiles in an Nx Workspace.
• Augmented the team’s productivity through the implementation of tailored bash aliases and functions. Explore some of the git bash aliases and functions I use daily.
