The Arc

Building a mobile app is easy to talk about and brutally hard to do well. Everyone has opinions about what the screens should look like. Nobody wants to do the actual work of translating business requirements into pixel-perfect designs that developers can build, users can understand, and stakeholders will approve. Hayley Zimmermann did that work.

At At Large, Hayley led the mobile app design process for Mobilization Funding's “Maximus” product — a native iOS and Android app that lets construction borrowers manage their loans, request disbursements, upload project photos, track progress, and communicate directly with the MF team. She managed the UX pipeline from the earliest Figma prototypes through to the shipped screens that borrowers actually tap on their phones.

What made Hayley exceptional wasn't just the design quality — it was the translation. She took the vision of what a construction lending mobile app should look like and turned it into something buildable. She coordinated the handoff between At Large's design team and Cloud Nimbus's Salesforce development team, making sure nothing got lost between a Figma artboard and the code that renders on a borrower's phone. That gap — between design and development — is where most products fall apart. Hayley made sure this one didn't.

What Hayley Brings

UX Design Leadership

Hayley owned the design pipeline for a fintech mobile app from concept to delivery. Not wireframes-in-a-vacuum design leadership — the real kind, where your decisions show up in production and actual borrowers tap the buttons you placed.

Mobile App Design

iOS and Android. Loan portfolio views, disbursement request flows, photo upload interfaces, project status tracking. Hayley designed screens that construction borrowers use in the field — on job sites, in trucks, on scaffolding. That requires a different kind of thinking than designing for someone at a desk.

Product Design Pipeline

From Figma prototypes to shipped screens, Hayley managed the full UX pipeline. She didn’t just hand off a PDF of mockups and disappear. She iterated, revised, and stayed engaged through the entire build cycle until what was on the screen matched what was in the prototype.

Design-Development Handoff

The gap between design and development is where most products die. Hayley coordinated the handoff between At Large’s design team and Cloud Nimbus’s Salesforce development team — making sure nothing got lost in translation between a Figma artboard and a React Native component.

Brand-to-Product Translation

At Large builds brands. Mobilization Funding needed a product. Hayley bridged that gap — translating At Large’s brand sensibility into a functional, usable mobile app experience that felt like it belonged to MF while actually working for real users with real money on the line.

From Figma to Field

Designing a construction lending app that works on a job site

Most mobile app design happens in a vacuum. A designer sits at a desk, opens Figma, and creates beautiful screens that look stunning on a 27-inch monitor. Then the app ships and it turns out nobody thought about what it's like to request a $50,000 disbursement while standing on a construction site with dust on your hands and the sun making your screen unreadable.

The Maximus app had to work for construction borrowers — people managing real money on real projects. Hayley designed the loan portfolio views so borrowers could see their entire relationship with Mobilization Funding at a glance. She designed the disbursement request flow with photo uploads so borrowers could document their progress and request funds from the field. She designed the project status tracking so everyone — borrowers, MF's team, inspectors — could see where things stood without playing phone tag.

She also designed the direct communication interface — a way for borrowers to talk to the MF team right from the app instead of bouncing between email, phone calls, and text messages. Every one of these flows had to work on both iOS and Android, had to feel native to each platform, and had to survive the handoff from Figma prototype to React Native code. Hayley made that happen.

How I Know Hayley

Through the Mobilization Funding / At Large / Cloud Nimbus ecosystem

When you're building a mobile app, you need someone on the design side who understands what developers need. Not just pretty mockups — actual specifications. Screen states. Error flows. Edge cases. What happens when the user has no loans yet. What happens when a disbursement request gets rejected. What does the loading state look like. That's the kind of thinking that separates a designer from a design leader.

Hayley was that person for Maximus. She managed the design pipeline at At Large and coordinated the handoff to our development team at Cloud Nimbus. Every Figma prototype came with enough context that our developers could build without guessing. When questions came up — and they always come up — Hayley had answers, or she'd get them fast.

Working with Danny on the product vision side and Hayley on the design execution side meant At Large brought both the “what” and the “how.” Danny drove the roadmap. Hayley turned the roadmap into screens. Cloud Nimbus turned the screens into code. That three-part chain only works when every link is strong, and Hayley's link never broke.

Why She Matters

Every app you've ever used that felt intuitive — where you didn't have to think about what to tap next, where the flow just made sense — someone designed that. Someone sat with the requirements, understood the users, mapped the flows, iterated on the prototypes, coordinated with the developers, and made sure what shipped matched what was designed. For Maximus, that someone was Hayley.

In a world where everyone wants to talk about AI and automation and the future of fintech, the thing that actually makes a product work is the UX. The screens. The flows. The buttons in the right place at the right time. Hayley did that work for a construction lending mobile app that real borrowers use to manage real money — and she did it with the kind of quiet professionalism that makes everything around her look effortless. It wasn't. It never is. That's the point.
