About

/Overview

GREENBAY is an AI-driven platform for mixed-fleet depot management, helping transit operators coordinate electric buses, chargers, and maintenance from a single interface.

Project GREENBAY Solutions

Category Enterprise B2B SaaS

Focus AI Mobility / Fleet Ops

Execution Year 2025-2026

01 · Context

I joined as the only designer at an early stage, working directly with the CEO to design the product from scratch, owning everything from information architecture to individual component states.

02 · Why GREENBAY?

Electrification has broken traditional depot logic. GREENBAY connects high-level service plans with real-time execution, so operations stay on track.

The Problem

50% Higher Costs

Mixed-fleet operators face massive overhead when using legacy diesel tools to manage EV complexity.

Financial Penalties

Charger failures and battery constraints lead to cancelled trips and heavy contract penalties.

The Visibility Void

A critical gap exists between high-level service plans and real-time depot execution.

The Solution

AI-Driven Loops

A single platform that synchronizes real-time energy data with operational schedules.

Smart Allocation

Automatically assigns vehicles, chargers, and parking spots based on real-time constraints.

Continuous Adaptation

Instant re-planning based on Live SoC tracking, delays, or infrastructure health.

03 · Brand Beyond the Product

Carrying the System Outward

The design system extended past the dashboard.

I led GREENBAY's full visual language, from the logo and color system to the materials used in sales conversations: the website, business cards for the founding team, and one-pagers used in client meetings.

04 · Sidebar redesign

Optimizing for Operational Speed

The sidebar is the primary interaction point within the Operational Timeline.

The sidebar is the primary interaction point on the Operational Timeline, where managers make real-time adjustments to keep the fleet on schedule. After the pilot, V1 carried too much cognitive load. Raw data without hierarchy made fast decisions hard under pressure.

The redesign was guided by three principles: Show, don't tell (progress bars instead of SoC numbers), Make absence meaningful (visible counts for blocked events), and Severity hierarchy (warnings clearly separated from errors).

What changed

›

Visual SoC

Static numbers → visual progress bars

›

Dependencies

Hidden labels → expandable counts

›

Hierarchy

Priority-based Warning/Error cards

›

Next Event

Proactive turnaround context

Before

Manual Logic - State of Charge (SoC) shown as percentages, requiring managers to perform "mental math" to estimate range.

Input Clutter - Redundant navigation arrows on date/time fields created visual noise without adding functional value.

Ambiguity - Undifferentiated alerts made it difficult to distinguish between minor warnings and service-breaking errors.

After

Instant Readability - SoC visualized as a progress bar (60% → 100%) for zero-effort comprehension of vehicle readiness.

Zero Visual Noise - Simplified date and time inputs designed for fast editing, removing unnecessary navigation iconography.

Severity Hierarchy - Clear separation between Warnings and Errors, ensuring critical operational issues are addressed first.

Predictive Context - Added a "Next Event" slot to help operators proactively plan the vehicle's turnaround after the current mission.

05 · Results

Measurable Operational Growth

Moving from manual monitoring to an AI-driven dashboard led to clear efficiency gains across pilot depots. Putting speed of comprehension first in the UI helped operators keep service running and avoid lost revenue in real time.

+21%

On-time performance

Reduction in missed or delayed trips by closing the gap between planning and depot execution.

+13%

Revenue growth

Protected long-term contracts through better automated KPI management and penalty avoidance.

54m

Earlier awareness

Average time gained on detecting operational issues, shifting from reactive to proactive management.

06 · Key Takeaways

Efficiency Over Aesthetics

In operations, speed of comprehension is the metric. Clarity isn't a design choice; it's a safety requirement.

Designing For Uncertainty

Missing data isn't a zero: it's a risk. "Unknown" states must be designed as rigorously as active ones.

Ownership & Speed

As a sole designer, working directly with the CEO taught me to align visual logic with business KPIs.

Iterate, Then Refine

The Sidebar V1 was built for speed; V2 was built for the user. Acknowledge tech debt, then solve it.
