Challenge

The problem we solved

Manual document review created days-long onboarding delays and a poor customer experience.

Existing process

What the client was doing before

Loan applicants uploaded ID documents, payslips and bank statements through a web portal. A compliance team member downloaded each file, opened it, extracted the relevant data by hand into a spreadsheet, cross-referenced it against validation rules and either approved or flagged the application. Processing a single application took 45–90 minutes. A backlog of 3–5 days was normal.

Solution

How we solved it

We built an AI pipeline to extract, validate and route document data with human review only for exceptions.

Lessons learned

What we learned from this engagement

Practical takeaways that inform how we approach similar projects.

  • Document extraction accuracy is not uniform — handwritten documents and low-resolution scans require a separate pre-processing step before LLM extraction.
  • Compliance teams need to own the validation rules — engineers should not define what counts as a valid payslip.
  • Audit logging from day one is not optional in financial services — it is a prerequisite for regulatory sign-off.
"Onboarding went from days to hours. Our team reviews exceptions instead of every single page."
