#1 about 1 min

Introduction to the SaaS company and technical team

An overview of the company, its role as a billing software provider, and the mission of its technical services team.

#2 about 2 min

Evolution from manual setups to automated monolith deployments

The engineering team transitioned from manual server setups to deploying a centralized monolith per customer account.

#3 about 2 min

Microservices adoption and the resulting architectural fragmentation

Hypergrowth naturally leads to microservices orchestration, bringing disconnected systems and disjointed authentication experiences.

#4 about 3 min

Customer challenges with decentralized authentication and entry points

Transitioning to multiple services fragments authentication methods and causes friction for customers seeking a unified platform.

#5 about 2 min

Designing a centralized API gateway and identity provider

Deploying an API gateway architecture provides unified endpoints across environments without paralyzing product feature timelines.

#6 about 2 min

Applying an ETL methodology to infrastructure configuration management

Adapting the extract, transform, and load pattern provides a reliable way to manage gateway configurations using Jenkins.

#7 about 1 min

Extracting API schemas automatically during continuous integration builds

Jenkins pipelines act as build engines that extract OpenAPI schemas from individual services and store them centrally in cloud buckets.

#8 about 1 min

Transforming API definitions into functional routing configuration files

Automated templating efficiently converts raw JSON API definitions into deployable routing and authentication configurations.

#9 about 1 min

Loading pre-configured artifacts into targeted customer gateway environments

Retrieving generated configuration files directly enables rapid provisioning of targeted customer infrastructure without manual intervention.

#10 about 2 min

Summarizing the automated deployment pipeline and templating workflow

A full workflow walkthrough reveals how Go templates compile API schemas into deployable gateway routes and static web documentation.

#11 about 3 min

Evaluating the past decision to adopt microservices architecture

A candid retrospective illustrates the operational drag and organizational costs associated with moving to microservices during company scaling events.

#12 about 2 min

Generating API documentation and managing infrastructure as code

Transforming service schemas into markdown supports automated website generation while tools like Terraform handle downstream environment provisioning.
