Experience

Terraform Module for a Google Cloud SQL Database

https://github.com/jeremielate/terraform-gcp-pgsql-module

A Terraform module used to instantiate a Cloud SQL PostgreSQL database with periodic backups enabled, automatic upgrades, and multi-zone replication by default. This module also creates database users and permissions.

SquashFS Rust Library

SquashFS is a revolutionary new file system built for modern needs in storage. It is optimized for read-only systems like content delivery networks. The original code is built in C and embedded in Linux Kernels but is not very practical to use as a library in third-party software.
I built a Rust-based library for working with SquashFS (building images from files and extracting files from images) in a way that is easy to integrate with any project.
