Developer Builds Cloud-Native Portfolio Using Terraform, AWS Lambda, and GitHub Actions

A developer with an IT Operations background completed the Cloud Resume Challenge, hosting a personal portfolio website using cloud-native infrastructure on AWS. Rather than using website builders like Wix or Squarespace, they built the project using Terraform for infrastructure-as-code, which they found more instructive than studying for their Terraform Associate certification. They leveraged an on-premises HashiCorp Vault running on a Kubernetes cluster to manage secrets and JWT authentication, keeping sensitive credentials off the cloud and behind a VPN. CI/CD was handled through GitHub Actions across two repositories — one for the frontend and one for the backend — each with separate testing and production branches. The project also incorporated an AWS Lambda-powered visitor counter with localStorage to prevent duplicate counts on page refresh.

Developer builds Spotify desktop pet controller using Godot 4 in first engine project

A developer transitioning from Unity created BelPet, a desktop pet application built with Godot 4 and C# that also functions as a Spotify playback controller. The draggable character sits above the Windows taskbar and lets users play, pause, skip tracks, seek, and adjust volume without opening the Spotify app. Because Spotify's Web Playback SDK is browser-only, the developer embedded a WebView inside Godot using the godot_wry library to run the required JavaScript. BelPet also uses a transparent, borderless, always-on-top window with custom mouse passthrough so clicks register on apps beneath it. Spotify's Development Mode restrictions limit full multi-device control for general users, though a workaround exists by creating a personal Spotify developer application.
