Master Module — eliminating a 3-month release cycle
A dynamic template engine inside Contentstack that consolidated 50+ marketing content modules into one configurable interface — giving business users direct control over template creation.
Problem
Under Oracle WCS, marketing messages on AEO's site were locked to a fixed library of content templates. Anything new — a layout the existing templates couldn't express — took months to ship: design → WCS development → UI development → QE → deploy. The library had grown past 50 modules, and every variation request that didn't fit one of them became its own multi-month project.
Moving to Contentstack was the chance to fix this. The headless platform handled content authoring well, but template flexibility wasn't going to come from the platform — it had to be designed.
Approach
I made two bets:
- Stop delivering fully formed HTML templates. Deliver data-driven templates instead — the front-end consumes structured content and decides how to render it.
- Build a dynamic template engine inside Contentstack that lets business users compose templates themselves.
The result was the Master Module: a single, configurable Contentstack module that consolidated the 50+ legacy modules into one engine. Business users compose layouts from a responsive 12-column grid (with push/pull adjustments for centering), then place lockups — combinations of copy, media, and CTAs — into the grid slots. The same module can produce countless layouts; engineering never has to ship a new "module" again.
Outcome
- ~3 months saved per template request — what used to be a coordinated effort across UX, design, engineering, and QE is now an authoring task
- Business users can produce unique modules on demand or build template libraries for repeated use
- The 50+ legacy modules collapsed into one engine, simplifying the platform significantly
What this says about how I work
The legacy library wasn't 50 modules — it was 50 stalled requests. Recognizing that pattern is what unlocked the design. Once you see "every new module is a re-skin of the same five layouts with different content," the right system writes itself: a grid, a lockup primitive, and a config surface.
The demo is the live Master Module — try composing a layout and watch the JSON output update in the console.
