Internal operations platform

Nanopay’s Back Office supported Customer Support, Onboarding, and Payment Operations across accounts, transactions, and customer records.

As the platform grew, information became harder to find and workflows increasingly fragmented. I led the redesign across research, information architecture, interaction design, and phased delivery.

Nanopay’s Back Office was the operational hub for customer support, onboarding, and payment operations. As the platform grew, critical information became increasingly difficult to find, workflows became fragmented, and teams relied on manual searching to complete everyday tasks.

I led the redesign across research, information architecture, interaction design, and phased delivery—improving how operations teams navigated accounts, transactions, and onboarding work while working within limited engineering capacity.

01 — The problem

Finding a transaction took longer than fixing it

Back Office had grown alongside the business, but its information architecture had not.

Different operations teams needed different information at different moments, yet the platform exposed dense screens and fragmented data without a clear hierarchy. Finding the right context often required manual searching and interpretation.

Design priorities

  • Make critical information easier to find and act on

  • Create a clearer hierarchy across operational records

  • Improve the system incrementally without requiring a full rebuild

02 — the Constraints

Improving a live system without rebuilding it

A full redesign wasn’t realistic. Back Office was already supporting active operations, while engineering capacity was limited.

I worked with the team to sequence improvements around the highest-friction workflows—allowing us to deliver value incrementally while moving toward a more coherent system.

Interviews with Customer Support, Onboarding, and Payment Operations revealed that the issue wasn’t simply UI complexity. The platform exposed plenty of data, but gave users little help understanding what mattered for the task at hand.

03 — Key decisions

Three decisions shaped the redesign

Sequence by operational friction, not screen/module

WHY

A full rebuild wasn’t realistic, and active operations couldn’t stop.

TRADE-OFF

Accept temporary inconsistency between phases to deliver useful improvements sooner.

Organize around shared records and operational tasks

WHY

Different teams needed different views of the same users, accounts, transactions, and onboarding records.

TRADE-OFF

Use a shared model with progressive disclosure rather than creating separate experiences for every team.

Bring onboarding documents into Back Office

WHY

External document handling created unnecessary searching and context switching.

TRADE-OFF

Increase the scope of the phase to remove a fragmented workflow and make documents part of the customer record.

PHASED DESIGN

01

Transaction & account views

The highest-traffic surface. Shipped first.

02

Transaction detail

Full visibility on a single record.

03

Documents & upload

Repository plus dedicated workflows.

04 — what changed

Mapping the redesigned workflow
Early user flows and concepts used to define relationships between key operational views.

Making operational information easier to scan and act on.

Transaction investigation was one of the highest-friction workflows.

I introduced a more scannable transaction view with flexible filtering and clearer account, status, and activity context—giving teams enough information to investigate quickly, with deeper detail available when needed.

Accounts & transaction views
Redesigned views brought status, account context, and related activity into a clearer operational hierarchy.

Bringing onboarding documents into the operational workflow

Onboarding specialists were managing customer documents outside Back Office, creating extra searching and context switching.

I designed a document repository and reusable uploader that brought categorization and document management directly into the customer record.

Onboarding document repository
Document upload, categorization, and management brought directly into the customer record.

05 — Impact

A stronger foundation without disrupting active operations.

The redesign created clearer navigation across accounts, transactions, and onboarding while allowing the platform to evolve without disrupting active operations.

More importantly, it established a shared information model that could support future operational workflows.

The project reinforced that internal tools are systems problems, and sequencing matters under engineering constraints.

Open to complex systems, ambitious
products, and thoughtful teams.
