Built the proof. Changed the roadmap.

Our digital ecosystem ran on a legacy Java monolith with an outdated WCMS. Publishing a simple news article took five manual steps. I built a composable proof of concept, benchmarked it against the existing platform, and the measured results informed the platform roadmap.

Context

Key challenges with the existing platform:

  • Deployments every 6–8 weeks
  • Strong dependency on developers for marketing pages
  • No drag-and-drop or modular editing
  • Large text fields misused for inline HTML
  • Manual asset resizing in Photoshop
  • Re-uploading multiple image sizes into the DAM
  • No dynamic media transformation
  • Limited performance optimization (static JPG/PNG)

Publishing a simple news article in the legacy setup: five manual hand-offs.

The workflow was slow, rigid, and operationally expensive.

Trigger

As Web Designer & Developer, I was directly exposed to these inefficiencies daily. At the same time, technological benchmarking showed how far modern headless CMS and media platforms had evolved.

What started as frustration became a structured initiative: I proposed building a proof of concept to validate whether a composable architecture could significantly improve speed, autonomy, and performance.

Strategic Vision

We needed:

  • A composable architecture (replace tools independently)
  • A flexible headless CMS
  • Greater marketing autonomy
  • Dynamic media transformation
  • CDN-based optimized delivery
  • Measurable performance improvements

After auditing multiple solutions, I selected:

  • Contentful for flexible content modeling
  • Cloudinary for on-the-fly media transformation and CDN delivery

I built a POC aligned with our existing e-commerce content model to ensure structural compatibility.

Experiment Design

To validate impact, I ran a controlled test. Six pages were each published once in the current system and once in the POC, and I measured publishing time end to end using a stopwatch.

Result

Publishing time was reduced by approximately 60%.

Legacy100POC≈ 40 (−60%)
End-to-end publishing time, legacy platform indexed to 100. Relative values from the internal benchmark.

This meant:

  • Same team could publish significantly more content
  • Or free capacity for higher-value initiatives
  • Reduced manual resizing and upload work
  • Increased clarity and consistency in workflow

Additionally

  • Dynamic media delivery improved Lighthouse scores
  • Eliminated manual generation of multiple image sizes
  • Reduced dependency on frontend developers for marketing execution

Trade-offs & Resistance

Main resistance: budget. Tool licensing costs were visible. Time savings and long-term scalability were not.

A deliberate constraint

We avoided testing directly with marketing teams to prevent frustration in case the initiative was paused. Validation was therefore conducted internally within the web team.

Strategic Insight

This project was not just a tooling upgrade. It revealed that:

  • Editorial workflows can be fundamentally restructured
  • Marketing autonomy can scale
  • Performance and flexibility are directly linked
  • Platform architecture directly impacts organizational speed

It shifted the conversation from “which CMS?” to “how do we design systems that enable velocity?”

Validated · informed the platform roadmap

The measured results were presented to stakeholders, and the composable architecture informed the platform roadmap.

Publishing times were measured end to end with a stopwatch on six pages, each published once in each system. The ~60% reduction is an internal benchmark run by the web team, not a study with the marketing teams.
