Is your team losing hours to manual data processing, format conversions, or repetitive document tasks? I build the tools and scripts that eliminate that work: reliable, low-maintenance, and built to last. With 20+ years of delivering automation and data solutions across industries, I turn complex requirements into clean, working software. Clients come back because the result actually holds up: no duct tape, no black box — just solid code their team can understand and maintain. I adapt the technology to your project (Python, C#, Java, XSLT, JavaScript), not the other way around. What I deliver: • Data Extraction & Conversion – Pull and transform data from XML, JSON, CSV, Excel, or legacy formats into PDF, HTML, Word/Excel, databases, or plain text — write once, publish everywhere. • Document & Publishing Automation – XSLT transformations, single-source publishing pipelines, automated layout and content placement (including Adobe InDesign scripting). • Workflow Automation – Scripts that eliminate manual steps, schedule processing, and enforce consistency across your data — so nothing falls through the cracks and no one has to babysit the process. • Custom Tools & Utilities – Command-line tools and lightweight desktop apps (Python, C#, Java) for data processing, report generation, or system-specific tasks. • System Integration – Connect disparate systems so data flows between them without manual intervention. I communicate throughout — not just at delivery. You'll always know where things stand, and you'll get documentation so your team isn't dependent on me afterward. If you have a data, automation, or document challenge, let's talk. I'll give you an honest picture of what's feasible and the smartest approach for your situation.
