Loan Documentation System

  • Client project
  • Desktop application
  • Solo built

A Windows desktop application that produces a member's full loan document set — application, promissory note, disclosure statement, and contract — from a single loan record, with the computed figures and member details merged into each form and ready to print. Designed and delivered solo in C# / .NET.

Under NDA

Client project — implementation details confidential

Internal workflows, data models, and system-specific flows are omitted out of respect for client confidentiality. Happy to walk through the architecture and approach on a call.

What I built

The capabilities behind the platform

  • One-step document set

    Generates the whole loan packet — application, promissory note, disclosure statement, and contract — from one member loan record.

  • Loan computation

    Amortization, interest, service charges, and net proceeds computed once and merged consistently into every form.

  • Template-driven forms

    Official form layouts kept as editable templates so a wording or rate change updates every future document without touching code.

  • Print & export

    Print-preview, batch printing, and PDF export with correct pagination for pre-printed cooperative letterheads.

  • Member & loan lookup

    Pulls member data and loan terms directly from the cooperative database, so forms can't drift from the system of record.

Skills demonstrated

What this build exercised end to end

  • Windows desktop development (C# / .NET, WinForms)
  • Database access & data binding (SQL Server, ADO.NET)
  • Financial computation — amortization, interest, charges
  • Document/report generation and print pipeline
  • Template-based document automation
  • Solo delivery — requirements, build, and rollout
