The Challenge

Enterprise data teams were drowning in fragmented tools with zero visibility into their cloud warehouse performance. I needed to create a solution that worked for both technical data engineers and business stakeholders.

No Real-Time Visibility

Teams couldn't see query performance or resource utilization in real-time, leading to reactive problem-solving.

Fragmented Workflows

Multiple disconnected tools created context switching and inefficient collaboration across teams.

Rising Costs

Without proper optimization insights, cloud computing costs were spiraling out of control.

Competing Platforms Analyzed

Deep research revealed that teams needed a unified platform that could serve both technical data engineers and business stakeholders, with progressive disclosure of complexity based on user roles and context.

The Solution

I designed a unified analytics platform with adaptive complexity—sophisticated capabilities for data engineers, accessible insights for business users, all through progressive disclosure and context-aware navigation.

Comprehensive Design System

Intermix design system documentation showing navigation states, filter icons, button variations, and interactive component specifications with hover, active, and disabled states

Material Design Foundation

Built upon Google's Material Design system to leverage established usability patterns while customizing components for data-heavy enterprise workflows. This provided immediate familiarity for users while ensuring accessibility compliance.

Custom Component Library

Developed specialized components for data visualization, filtering, and analytics workflows that weren't available in standard design systems. Each component included comprehensive state documentation and interaction specifications.

Scalable Architecture

Created a modular system that could grow with the platform's needs, including detailed specifications for navigation states, button variations, icon treatments, and interactive feedback patterns.

Developer Handoff

Provided comprehensive documentation with hover states, active states, disabled states, and interaction specifications that enabled seamless implementation by the engineering team.

Before & After: Interface Evolution

Before
Original Intermix interface showing cluttered layout with dark sidebar navigation, multiple sections, and complex query details view with recommendations and execution information

Complex interface with cluttered navigation and overwhelming information density

After
Redesigned Intermix interface featuring clean, streamlined layout with simplified sidebar navigation, organized content sections, and improved visual hierarchy for better user experience

Streamlined design with clear hierarchy and focused information architecture

Advanced Filtering & Personalization

I designed a sophisticated filtering system that allows users to create complex, personalized reports with multiple conditions and logical operators, enabling precise data analysis across different warehouse sources.

Advanced filtering interface showing expandable filter options with source selection, job properties, operators, values, logical connectors (AND/OR), table operations, and customizable report parameters

Dynamic Filter Building

Users can build complex queries by combining multiple filter conditions with AND/OR logic, allowing for precise data segmentation across different warehouse sources like Redshift, Snowflake, and BigQuery.

Expandable Conditions

The interface supports unlimited filter additions with intuitive "Add Filter" buttons, enabling users to create increasingly sophisticated queries without overwhelming the interface.

Contextual Operations

Separate sections for job properties and table operations provide contextual filtering options, allowing users to focus on specific aspects of their data warehouse performance.

Key Design Decisions

Unified Dashboard Approach

Instead of separate interfaces for different user types, I designed a unified dashboard that adapts its complexity and focus based on user roles and current tasks. This reduces training overhead and enables better cross-team collaboration.

Impact
-45% Training Time
Result
+89% Feature Discovery

Context-Aware Navigation

Implemented a navigation system that maintains context across different views and workflows. Users can drill down into specific queries or workloads without losing their place in the broader analysis.

Progressive Disclosure

Designed layered information architecture that presents high-level insights first, with the ability to progressively reveal more detailed data and technical information as needed.

Outcome
-68% Time to Insight

Comprehensive Workload Management

The final design integrates workload selection, job management, and real-time analytics into a cohesive interface that enables data teams to efficiently monitor and optimize their cloud warehouse operations.

Workload Organization

Intuitive sidebar navigation allows users to quickly switch between different workloads and maintain context across complex data warehouse environments.

Real-Time Analytics

Live query count visualization and trend analysis provide immediate insights into workload performance and resource utilization patterns.

Grouped Analysis

Smart query grouping with visual indicators helps users identify patterns and optimize similar operations across their data warehouse infrastructure.

Integrated Workflow

The final interface seamlessly combines workload selection, source filtering, and real-time analytics into a unified experience. Users can navigate between different Redshift, Snowflake, or BigQuery workloads while maintaining their analysis context, enabling efficient cross-platform optimization and monitoring workflows.

Conclusions and Reflections

The Intermix.io platform redesign taught me valuable lessons about designing for complex enterprise data environments as the sole designer on the project. Working with data engineers and business stakeholders required deep understanding of their workflows and the critical nature of real-time data insights.

What Worked Well

Progressive Disclosure Strategy
Creating adaptive complexity that served both technical and business users without overwhelming either group
Advanced Filtering System
The expandable filter interface enabled users to create sophisticated queries while maintaining simplicity for basic use cases
Cross-Team Collaboration
Regular sessions with engineering and customer success teams provided crucial insights that shaped key design decisions

Key Learnings

Enterprise Data Complexity
Data professionals need both high-level insights and granular details accessible within the same workflow
Personalization is Critical
Advanced filtering and customization capabilities became essential for user adoption in enterprise environments
Context Preservation
Maintaining user context across complex data exploration workflows was critical for user success

Looking Forward

This project reinforced my belief that successful enterprise design requires balancing user needs with technical constraints while maintaining focus on the critical nature of data-driven decision making. The unified platform approach I created became a foundation for Intermix.io's continued growth, demonstrating the long-term value of thoughtful design systems in complex data environments. As the sole designer, I learned to effectively collaborate across multiple stakeholder groups while maintaining design consistency and user-centered principles.
