• RAPID DEPLOYMENT: Launched a full-scale CRM & Sales system for Droplet (Netherlands) in a record 10 days, enabling immediate lead tracking and automated follow-ups.
• INTERNATIONAL COMPLIANCE: Implemented Odoo 17 for Lviv Croissants (France), ensuring 100% compliance with strict EU/French fiscal regulations and complex POS hardware integration.
• DATA-DRIVEN GROWTH: Developed custom integrations for Exxentric (Sweden), syncing Odoo with WooCommerce, BigQuery, and Stripe for advanced predictive sales forecasting.

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.

At A Glance: XML-RPC
Whether you are developing a personal website or blog to share ideas and information with audiences worldwide, or opening an online storefront to share your product or service with prospective new customers, a dynamic and original web presence is essential. Consumers today expect much more than just a quality product or service; they expect easy, quick accessibility, and an appealing presentation. This applies across industries, from news media to entertainment, and food and beverages to apparel. A qualified XML-RPC expert and web developer can assist you in ensuring your web presence is one that will entice online visitors and keep regular web patrons coming back for more. One of the most common sites in which XML-RPC is used is WordPress. WordPress is used by everyone from photographers and craftspeople to media outlets due to its great deal of versatility and intuitive, customizable user interface. The XML-RPC functionality on WordPress operates as an API that gives developers who make apps or other services a method by which to write customized applications that can do a variety of tasks you’d typically do manually while logged in. These include publishing a post, editing a post, uploading a new file, deleting a post, and managing comments.
On Upwork, you will have access to numerous XML-RPC experts and web developers who can assist you in installing, implementing, managing, and troubleshooting any site using XML-RPC. These highly-qualified freelance professionals are knowledgeable in various aspects of web design and programming, and will ensure that your site accurately conveys the originality and ingenuity of your ideas, products, or services.
