Operations Manager turned Developer

Automating Business with
Intelligent Software

I build proprietary desktop applications that bridge the gap between complex operations and efficient automation. Specializing in Python, GUI development, and Hardware Integration.

Technical Proficiency

Python

Multi-threading (QThread), dynamic module loading (importlib), context managers, and complex subprocess management.

PySide6 / Qt

Complex widgets (QTableView), custom signals/slots, QSS styling, and non-blocking UI patterns.

SQL & Databases

Complex raw SQL queries (PostgreSQL/SQLite) for transactions. Deep understanding of DB fundamentals without ORMs.

System Automation

Automating OS-level tasks (screen capture via mss, SSH tunneling) and interacting with cloud CLIs (Google Cloud SDK).

Technical Services

Solving operational bottlenecks with code.

Custom ERP & CRM

Building "sidecar" applications that extend QuickBooks and standard ERPs with custom manufacturing logic and inventory tracking.

Workflow Automation

Eliminating manual data entry using Local AI, OCR pipelines, and intelligent document processing agents.

Desktop GUIs

Developing modern, cross-platform desktop applications (Windows/Mac/Linux) using Python & PySide6/Qt.

Hardware Integration

Bridging the gap between software and industrial machines (Laser Engravers, Printers) via TCP/IP and Serial protocols.

Featured Projects

A selection of proprietary tools built for clients.

FabLogic HG Demo

FabLogic HG

Hose & Gasket Edition

The specialized Hose & Gasket edition of the FabLogic suite. A standalone desktop bridge for QuickBooks that solves complex inventory challenges by implementing custom "nesting" algorithms to optimize material yield and minimize scrap.

AiInvoiceRecon Demo

AI Invoice Recon

Local AI / Fintech

An on-premise pipeline using Local Vision Language Models (VLMs) to extract structured financial data from PDF invoices. Features a "Self-Correcting" Pydantic validation layer that mathematically verifies AI output to prevent hallucinations in financial records.

PDF Suite Demo

PDF Suite

Operations Tool

A "Swiss Army Knife" for document operations. Integrates OpenCV for automatic scan cleanup (deskewing/thresholding) and features a bidirectional OCR interface where clicking text on the PDF highlights the raw text for rapid correction.

Smart Image Editor Demo

Smart Image Editor

Architecture

A scalable desktop application built with a strict Plugin-Based Architecture. Allows for "hot-extending" functionality (like AI Background Removal) by dynamically loading Python modules at runtime. Handles heavy batch processing via threaded workers.

CertCreator Demo

CertCreator

Industrial Automation

Hardware-integrated automation tool that bridges digital orders with physical Epilog Laser Engravers. It programmatically generates SVGs for metal tags and streams printer-specific commands (PRN) directly to hardware IPs via TCP/IP sockets.
