I engineer modular Python utilities, command-line pipelines, and desktop GUI applications with a strong focus on safety, responsiveness, and observability—using background worker threads (QThread), pre-execution dry-run validation, defensive error handling, and multi-channel logging (GUI, FileHandler, and StreamHandler).

• 🐍 Core Stack: Python, PySide6 (Qt), pathlib, csv, json, argparse, logging, NumPy
• 🖥️ Desktop GUI Engineering: Non-blocking QThread background workers, custom Qt Stylesheets (QSS), and live Signal(str) log consoles
• ⚙️ Workflow Automation: Recursive directory auditing, bulk file renaming & sanitization, media asset organization, and high-volume JSON/CSV batch pipelines
• 🧠 Machine Learning & Data: Vectorized numerical computing with NumPy, regression modeling from first principles, feature scaling, leak-free train/test workflows, and evaluation metrics

Responsive PySide6 Desktop File-System Auditing & CSV Inventory Tool

• Recursively audits directory trees using pathlib and extracts structured OS metadata (Filename, Extension, Parent_Folder, Size_MB, Last_Modified, Full_Path).
• Executes scans inside a background QThread worker (ScanWorker) with real-time progress signals and mid-scan cancellation so the GUI never freezes.
• Routes runtime diagnostics simultaneously to the PySide6 log panel, console, and logs/app.log, and exports clean reports via csv.DictWriter.

Safe Desktop Bulk File Renaming & Sanitization Utility with CI/CD Packaging

• Implements a strict Scan → Plan → Validate → Preview → Execute workflow for bulk file renaming with 3-digit zero-padded indexing (<prefix>_001.ext).
• Includes regex filename sanitization (cleaner.py), dry-run GUI console previews, and pre-execution collision checks (validator.py) to prevent accidental overwrites.
• Packaged as a standalone Windows executable via an automated GitHub Actions + PyInstaller workflow.

Python Automation Pipeline Scripts (day_01–day_30), 10k+ CLI Batch Auditor & QSS-Styled Desktop Organizer

• Progresses through 30 root automation scripts (day_01_basics.py to day_30_gui_basics.py), a modular scanner package (day_29_modular/), and the Pro Media Asset Manager (media_organizer/).
• Pro Media Asset Manager (media_organizer/) is a dark QSS-styled PySide6 desktop app that audits directories and automatically organizes files into category folders (Images, Videos, Audio, Documents, Archives, Code) without overwriting existing assets.
• Includes a CLI batch JSON verification and telemetry engine (day_27_pipeline_summary.py) with --dry-run simulation and automated JSON summary reports.

Code-First Machine Learning & Numerical Computing Implementations

• Implements univariate and multivariate linear regression, analytical gradient descent, and vectorized forward/backward passes from scratch in Python and NumPy (Days 1–17).
• Covers Min-Max feature and target scaling, leak-free train/validation/test split pipelines, overfitting vs. underfitting diagnostics, validation-based model selection, and regression evaluation metrics (MAE, MSE, and RMSE implemented from scratch in NumPy on Day 16 and evaluated with scikit-learn's sklearn.metrics on Day 18).
