About

SAIGU Monitoreo is a B2B platform used by medium and large industries in Mexico and Colombia to monitor real-time data on water, air, and grease consumption. After 10+ years as a successful desktop platform, the business saw an opportunity to expand into mobile and improve customer experience in the field.

I led product design for SAIGU’s first mobile app, built natively for Android. I also supported front-end implementation, ensuring the final experience stayed faithful to the design and performance requirements.

Goal

Launch a mobile-friendly experience for SAIGU customers working on-site or away from desktop environments — with a focus on real-time data access, ease of use, and future scalability.

Understand Business Needs

The leadership team wanted to:

• Maintain strong client relationships
• Extend platform reach via mobile
• Improve accessibility for users working in the field

Given that the majority of users in the target markets used Android phones, we decided to prioritize Android for the initial release.

Scoping & Information Architecture

We reviewed the desktop platform’s features and collaboratively prioritized which would bring the most value on mobile, without overwhelming users or overcomplicating the MVP.

I led the creation of the information architecture, advocating for:

• Real-time data prioritized at the top
• Features that supported quick decision-making in the field
• A clean, minimal structure that could evolve over time

This architecture became the shared foundation for design and development discussions.

Wireframes & User Validation

I started with hand-drawn user flows, then moved into mid-fidelity wireframes using Adobe XD.

Before finalizing designs, I interviewed and tested concepts with field technicians — the primary mobile users. Their feedback directly influenced how we structured navigation, surfaced data, and designed notification triggers.

Usability Testing & Iteration

I ran remote usability tests with existing clients using clickable prototypes.

Key findings:

• Users strongly preferred a clean, minimalist interface
• Data hierarchy was initially unclear; we restructured key screens for better scannability
• 80% of testers requested real-time notifications, which we then prioritized for the MVP
• A newly released desktop feature (“Today’s Water Consumption”) was flagged by the PO as essential and was scoped into the mobile version with dev team approval

Design system & Branding

The app followed SAIGU’s branding, adapted for mobile. I emphasized a lightweight, breathable UI to support fast, distraction-free use in industrial settings.

To humanize the experience, I integrated Mizu, the company’s mascot (also designed by me), into onboarding — giving the app a friendly, branded tone without compromising usability.
