context

Nitsa AI is AVANA Companies’ deal-management platform for commercial lending. Its document manager handles the flow of borrower documents every deal depends on — tax returns, financial statements, debt schedules — with AI-assisted classification. 

I’m the sole designer on the team, working end-to-end with a PM, engineers, and the lending team — processors, underwriters, and portfolio managers. What started as document management is now growing into a full deal-management system.

problem

Every document arrived by email. Processors downloaded attachments, renamed them to a naming convention, filed them into Box folders by hand, tracked completeness in Excel checklists, and emailed “docs due” lists to borrowers.

Hours of skilled analyst time went to filing, misfiled or missed documents stalled deals, and there was no single source of truth for what was outstanding.

RESULTS & impact

7 min → 30–60 sec

to review and confirm a document now — with 100–150+ documents per deal

70%

of documents are confirmed without a single edit to the AI’s suggestion

Solution overview

Action

Designed an AI-assisted classification workflow with a human in the loop: the AI suggests the document type, owner, period, and deal — an analyst confirms or corrects in one action. One workflow replaced four manual tools: email triage, the Excel checklist, hand-filing in Box, and status emails.

what was built (high level)

Classification workspace

PDF preview beside the AI suggestion with a confidence badge — confirm, or reject with a reason, then jump to the next document in the queue

Incoming files hub

Every uploaded document across deals with its AI classification status, document type, linked deal, and assignee

Document checklist

Required vs optional documents per borrower and guarantor, auto-updated as files are confirmed

The classification workspace

problem

This one screen had to solve two hard problems at once: earning trust in AI on financial documents — where a misclassified tax return isn’t tolerable — and staying fast across the 100–150+ documents a single deal can carry.

I designed it so the AI proposes and the analyst decides: every suggestion ships with a confidence level, every decision feeds the learning loop, and the whole thing runs as a queue instead of a file browser.

what I Designed

  • Confidence badge on every suggestion → analysts see at a glance how much to trust each classification

  • One-action confirm, then next → the common case is a single click across a deal’s 100+ documents

  • Structured rejection reasons → incorrect details, poor quality, duplicate, not relevant — data that feeds the AI learning loop

  • Per-deal queue + edge cases → a “1 of 3 in this deal, 10 remaining” sidebar, plus exact-duplicate detection and multi-type files

Validation
(usability testing & release stats)

Trust grew with transparency

Visible confidence levels made it easier for analysts to accept the AI’s suggestions

The common case is one click

70% of documents are confirmed without any edits to the AI classification

Review became a flow

Handling a document dropped from 5–7 minutes to about one

Tested with the real team

Moderated usability tests with processors and portfolio managers shaped the flow

The checklist that replaced the spreadsheet

problem

Completeness used to live in an Excel sheet, with “docs due” lists emailed out by hand. Nobody had a live view of what a deal still needed or who owed it — and requirements shift with each deal’s configuration.

I designed a checklist tied to each deal: required vs optional documents per borrower and guarantor, updating itself as files are confirmed in review.

what I Designed

  • Required vs optional per role → each borrower and guarantor gets its own document set, matching how deals are structured

  • Auto-updating status → items complete themselves as documents are confirmed, so the list is always current

  • Single source of truth → replaces the Excel sheet, so everyone sees what’s pending and who owns it

  • Powers borrower requests → the same checklist drives what’s asked for through the Obligor portal, not manual emails

Validation
(usability testing & release stats)

Completeness at a glance

Anyone can see what a deal still needs without opening a spreadsheet

Ownership is clear

Required-vs-optional per borrower and guarantor makes it obvious who owes what

Fewer status emails

Auto-updating status cut the manual “docs due” follow-ups

Ready for the portal

The same checklist will drive document requests in the borrower-facing Obligor portal

Results & what’s next

iteration

Not everything survived the first version. Deals move through stages, and v1 gave every stage the same document-management design — but after closing, a deal enters Portfolio and lives for years, collecting documents annually until the loan is paid off.

A stage-based structure couldn’t express that yearly rhythm — so I redesigned Portfolio as structurally different: documents grouped by year until the loan is paid off, with the same confirm-and-reject review motion carried over.

Shipped and used daily

The lending team runs every active deal’s documents through the manager

Still improving after release

Ongoing stats and behaviour analysis keep feeding design updates
