  • CAD Handwheel Generator

    It is a naval challenge project: it is too costly for a naval craft to carry extra handwheels, and each naval craft may have many different-sized handwheels.

    As an alternative solution, vehicles will have a computer and a 3D printer. An operator can enter the handwheel dimensions and output a procedurally generated CAD file for 3D print to replace any broken handwheels.

  • Conference Attendance Web App

    A Node.js-based CMS that allows users to register for interesting talks and pay through PayPal. Added administrative functionality to organize attendees, batch email attendee assignments, and export attendance as CSV. The web application is re-run by the client yearly.

  • EE Lessons

    Empowering Education (EE) is a nonprofit that provides mindfulness content for educators to bring to the classroom. Users will log in to the online service to access lessons, download content, and see usage examples.

    The chosen solution to the project was to build a custom post type in WordPress that integrates with pre-existing functionality. This allows the EE editors to manage the lessons entirely by themselves. Including managing content, the template, additional data, and user access.

    This project allowed me to work with WordPress and extend its feature base. I was able to create a custom post type. I integrated with advanced custom fields to build the form. EE already chose Divi as their templating engine, and I was able to create a custom template. Lastly, they use Memberful for user role access. By utilizing each of the integrations already present, EE can manage this feature on their own.

  • WordPress Page Speed Optimization

    Candle Inc was looking to improve its Core Web Vitals to support better SEO. With only access to WordPress, I configured several plugins to speed up the site. As a result, the company's Core Web Vitals went from 25 to 65.

  • Power Automate Flow for Non-technical Users

    The project served as a business process intermediary and proof-of-concept. We used Microsoft Forms as a front end, Microsoft Excel as a database, Power Automate as a business layer, and Power BI as an administrative tool. Internal users could look clients up in the Power BI system and enter a unique ID in the Microsoft Forms to allow updates. Several Power Automate flows were built from Microsoft Form triggers. One Microsoft Form was a 100+ questionnaire. The Power Automate design chosen was the ease of maintenance for a non-technical user. For example, conditional branches were never more than a single layer deep—the management from the block editor would be complex.
