Introduction

One Market Calendar (OMC) is a centralized marketing hub designed to help 900+ users seamlessly plan, execute, and scale high-impact campaigns.

I led this project end-to-end across research, design, and implementation, collaborating closely with 10+ partners across product, engineering, and delivery.

"Looks much more aligned with other Google tools and the side navigation is great."

"I love the look of it though. I really do. I think it's a huge improvement from what we currently have — it's such an improvement from a visual perspective."

Key features

Feature 01

Dynamic input fields

Provides a guided experience by adapting the interface to user selections, progressively revealing only relevant input fields.

Feature 02

Gemini as a copilot

Integrated Gemini into the workflow to answer questions, explain fields, and suggest correct inputs.

Feature 03

AI auto-population

Integrated Gemini so users can upload a document to auto-fill the form, eliminating manual typing.

Feature 04

Missing field highlights and real-time guidance

Highlights missing fields inline to reduce errors and prevent workflow interruptions.

Measuring success

A side-by-side look at the workflow before and the UX impact after launch.

Before

  • Disconnected tools

    6+ disconnected tools to plan and manage campaigns.

  • Lack of automation

    Re-entering duplicate details across multiple systems.

  • Complex workflows

    10–20 minutes lost per session navigating tools.

After

  • Centralized platform

    Unified everything into a single campaign hub.

  • AI automation

    Auto-fills forms from briefs with 80% accuracy.

  • Guided experience

    Inline guidance and progressive fields reduce steps by 92%.

My role

I led end-to-end product design from discovery to delivery, focusing on several core areas of responsibility:

  • Product Design: Led end-to-end research, prototyping, and handoff.
  • UX Research: Identified core workflow inefficiencies.
  • AI Chatbot: Designed AI-driven chatbot interfaces.
  • Usability Testing: Validated designs through iterative user testing.
  • Collaboration: Partnered across product, engineering, and delivery.

The problem

Managing a campaign required navigating 6+ disconnected platforms. Without workflow integration, constant data duplication cost teams 10 to 20 minutes per session in context switching.

Why AI made sense

Rather than optimizing manual data entry, I redesigned the workflow so AI extracts information from uploaded briefs and pre-populates the form.

Marketers shift from entering data to reviewing AI-generated content, reducing effort while maintaining control.

Design tradeoffs

Automation vs. control

Fully automating campaign creation saved time but reduced trust. I introduced AI as an optional side panel that generated a starting point, allowing marketers to review and refine campaign details before submission.

Flexibility vs. reliability

Campaign briefs varied in structure, so I prioritized extracting the most common fields first to improve reliability while supporting future expansion.

Innovation vs. familiarity

Rather than introducing an entirely new workflow, I embedded AI into the existing campaign creation experience using Google Docs as a familiar interaction model. This reduced context switching and lowered the learning curve for marketers.

From fragmentation to focus

To understand where time was going, I mapped out the full campaign workflow and identified three consistent patterns:

01

Disconnected tools

Users switched between multiple systems.

02

Lack of automation

Manual data re-entry across platforms.

03

Complex workflows

The system lacked intuitive usability.

How Might We

How might we help marketers complete campaign workflows faster, without manual data entry and tool switching?

The Old Experience: Built for Systems, Not Marketers

It was complex and hard to use, creating a fragmented workflow with severe data overload.

Designing the future workflow

To address the issues I uncovered, I focused on three key areas of improvement:

01

Centralized platform

Unified essential features into a single hub.

02

AI automation

Integrated Gemini to eliminate manual setup steps.

03

Guided experience

Refreshed the UI to ensure an intuitive workflow.

Reflection

Owning this project end-to-end taught me that meaningful product improvements come from understanding the entire ecosystem, not just individual interactions.

By aligning user needs, business objectives, and AI-powered capabilities into a cohesive workflow, I was able to create a more intuitive and scalable experience.
