Taxfix

Jan `22 - Jun `23

1 year

We worked with the engineering team building from scratch the backend part and cloud infrastructure of the application, written in Typescript using NodeJs and Fastify as a framework, MySQL as a database (using google cloud SQL), and GCP as our cloud platform with 3 different projects and instances deployed with Google Kubernetes Engine (integration, staging, and production).

Responsibilities & achievements

Our services communicated with other services using google pub/sub. The credentials were delivered through google secret manager into the different environments, locally we authenticated every user managing their permissions through Google IAM and using google cloud SDK to get the user credentials and use it to connect to our databases with google cloud SQL proxy. Everything was integrated with a CI/CD pipeline in gitlab using a mirror repository connected to our github monorepo that hosted our SDK, migration, API, and some other packages. This pipeline was in charge of building the application, testing it, building the artifact, and ultimately deploying it to every single one of the instances.
