CI/CD Optimization for a Multi-Tenant SaaS Lending Platform

A US-focused B2B SaaS company is building a cloud-based Loan Management System (LMS) for banks and brokers.

The platform replaces outdated desktop lending tools with a modern alternative, built for scalability, collaboration, and ease of use.

As the platform matured, the team faced challenges managing code deployments across multiple environments. The codebase used a monorepo architecture with three active projects: Pricers, Borrower, and LMS, each handled by separate teams.

They needed:

• Isolated deployments to prevent cross-app disruptions

• More control over what goes live in each environment

• A clean, efficient release process for dev and QA

The engineering team aimed to:

• Eliminate unintended cross-project deployments

• Enable app-specific deployments tied to verified changes

• Speed up QA and release workflows

• Reduce coordination overhead across dev, test, and staging

• Increase confidence and control in the CI/CD pipeline

The shared pipeline created deployment headaches:

Pushing a small update to one app triggered builds for all, causing unintended side effects.

Unverified code from one team would interfere with others’ test cycles.

Leads couldn’t easily choose which changes were ready for deployment, slowing velocity and increasing risk.

To resolve these issues, we redesigned the CI/CD workflow for project-level deployment isolation.

We explored two options:

• Tag-Based Deployment – Each project used unique version tags to trigger builds

• Label-Based Deployment – GitHub labels defined which app to deploy, per pull request

The team selected Label-Based Deployment for its flexibility and minimal overhead.

We rebuilt the GitHub Actions workflows to:

• Deploy only the selected app, based on applied labels

• Avoid unnecessary rebuilds for unrelated projects

• Create environment-specific jobs for staging, demo, and production

QA and tech leads gained clear control through:

• Label-driven triggers tied to specific branches

• Verified code paths and automatic logging

• Faster cycles with fewer coordination dependencies

We leveraged a clean tech stack focused on speed and clarity:

Next.js with TypeScript – Monorepo architecture across all three apps

GitHub Actions – Custom pipelines with label-specific triggers

Environment-Specific Workflows – Controlled builds for staging, demo, and production

The restructured CI/CD system delivered clear and measurable outcomes:

Changes to one app no longer affected the others, reducing production issues.

No more wasted time testing unrelated updates; each release was targeted and clean.

Engineers deployed faster, with fewer blockers or manual reviews.

Clear logs, structured flows, and lead-controlled deployments made releases smoother and more predictable.

The client gained:

• Fully isolated deployments across a shared monorepo

• A lean, label-driven CI/CD pipeline tailored to multi-project teams

• Fewer errors, faster cycles, and better coordination between dev and QA

• A scalable foundation to support future growth and product complexity
