Offline Compliance App: Excel-to-App Conversion

I am seeking a skilled software developer to help me build a local compliance desktop application that replicates the logic and functionality of Excel workbooks. This application will be used for performing Risk and Maturity Assessments and scoring.

The project will be divided into two phases:

Phase 1 Goals:

- Convert Excel logic, dropdowns, scores, and formulas into a working application
- Use form-based UI with backend logic engine
- Match Excel score outputs exactly (color codes, conditional formatting, calculated fields)
- Export executive summaries and POA&M reports to PDF and Excel
- Save session data locally (JSON or SQLite)

Phase 2 Ready:

- Codebase must be modular and cloud-portable for future deployment as SaaS
- Logic must be reusable in web API (e.g. FastAPI or Django)
- UI eventually upgraded to React (or compatible stack)

I have already identified all the specific Excel functionalities which need to be replicated in the application including dropdown menus, conditional formatting, calculated fields, and links.

The ideal candidate for this job will have:
Area Skills Needed
Frontend (Local) Streamlit (Python), OR Electron + React for UI
Backend Logic Python (Pandas), Formula-to-function conversion
Data Handling JSON, SQLite (read/write, validation, modular schema)
Report Export PDF and XLS generation (xlsxwriter, reportlab, pdfkit)
Testing / Validation Unit testing, input/output parity with Excel logic

I look forward to seeing your proposals.
