  • reaMIXed Mixing Contest

    I designed this site as a new place for audio mixing engineers to hone their skills and share their methods. The application is built with a React front end, Node.js back end with a MongoDB Atlas database, and Redux for state management. Serverless hosting is handled via Google Cloud Run using Docker for deployment.

  • SofaWorks Review/Product Info Sections

    I worked as part of an agile remote team to develop an online furniture retailer's product page. I created the review and product details sections and developed a proxy to deploy the other microservices. I used Styled Components for the animations and MySQL to handle the data. Micro-services and proxy were deployed to Amazon Web Services Elastic Containers.

  • Craftworkery: Micro-service Deployment

    For this project, I deployed a photo carousel micro-service for the product page of an online store selling bespoke products as part of a distributed remote team using Agile practices with daily stand-ups.

    The PostgreSQL photo database contained over ten million products with 22 million product images. This was deployed to AWS Elastic Containers with round-robin load balancing to improve the response times under heavier loads.
