SpendWise AI ā Executive Financial Audit Dashboard
š Project Overview
SpendWise AI is an executive-grade financial intelligence dashboard designed to ingest multi-currency transactional logs and deliver automated data auditing, dynamic runway projections, and algorithmic risk flags. Built with a responsive dark-themed corporate UI, this application transforms raw transaction histories into an interactive compliance and financial health management portal.
š Key Engineering & Analytics Features
Multi-Currency Vectorized Financial Metrics: Separates and aggregates transaction lists based on sign conventions using vectorized arrays. It computes real-time total income, total expenses, and net balance under flexible, user-selected global currencies (including PKR, USD, and GBP).
Predictive Financial Runway Engine: Dynamically calculates an individual or business's average daily burn rate by calculating the elapsed delta between the earliest and latest transaction timestamps. If a dataset lacks chronological entries, a robust safety fallback algorithm takes over, shifting to an adaptive 30-day timeline simulation to maintain zero application runtime failures.
Algorithmic Outlier & Anomalous Spending Audit: Employs a dynamic rule-based statistical thresholding mechanism ($3\times$ the calculated mean expense value). Any transaction breaching this boundary is caught by an automated inspection pipeline, which marks the record with an operational warning (š© RED FLAG: High Spend) and isolates it in a standalone high-risk ledger for immediate review.
Production-Grade Data Resiliency: Engineered with an assertive preprocessing pipeline including automatic column trim operations (df.columns.str.strip()) and strict numeric enforcement (pd.to (http://pd.to)_numeric with errors='coerce'). This ensures the app safely processes poorly formatted, manually generated, or commercial banking files without crashing.
š ļø Technology Stack
User Interface: Streamlit (Python-powered, data-reactive framework)
Data Processing Layer: Pandas & NumPy (Vector mathematics, database filtering, and string normalization)
Custom Styling: Embedded custom CSS styling overrides for deep-tint metric elements

TruePKR ā The Freelancer's Reality Check
Overview
TruePKR is a web-based financial utility application built to bring absolute transparency to Pakistani freelancers, independent contractors, and remote teams receiving foreign remittances. It strips away the mystery of hidden local digital wallet conversions and mandatory fiscal policies, providing an honest, real-time assessment of actual net income before execution.
The Core Problem
Most global currency conversion tools display standard, unencumbered interbank rates. This causes unexpected friction for remote workers who realize their actual bank deposits are noticeably lower due to hidden intermediary bank spreads and mandatory local regulatory tax slicing.
The Implemented Solution
Custom Spread Analysis Engine: Calculates dynamic transactional losses based on the selected local fintech payment processor (e.g., SadaPay, NayaPay).
FBR Compliance Selector: Built-in dynamic calculation logic mapping legal withholding tax rules down to the 0.25% export tier if PSEB registered or falling back to the standard 1% baseline.
The Clarity Threshold Banner: Surfaces an instant, high-contrast digital invoice receipt summarizing the exact total leakages, proving exactly how much of their hard work went to processing fees.
