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.

If your data is stuck in the wrong system, in messy files, or behind an awkward API, I can help. I turn complex data problems into working systems and usable deliverables. I help clients move data between platforms, automate manual work, clean up unreliable exports, and build workflows that save time and reduce errors. Whether the deliverable is a program they can keep using, or a clean CSV, Excel file, report, or database, I can make it happen. Most of my work is API integrations, ETL pipelines, backend automation, data processing, and data migrations. I'm at my best when the problem is not clean or perfectly defined. I'll solve that problem first. I build data workflows that are meant to hold up in real use. I work with complex APIs, big JSON or XML data files, elaborate schema, folders full of CSV and Excel files, and large datasets where correctness matters. The result is a cleaner dataset, a dependable program, or a responsive and well-designed workflow. If you need a dependable program, a solid new system, or a clean final dataset, I can help.
