About

I fix and maintain WordPress and WooCommerce sites, including custom plugins and payment integrations. Start with one clear issue or a small improvement, not an unnecessary full rebuild.

I built and still maintain Gringo, a restaurant WooCommerce store with a custom theme, custom plugins and OTP/SimplePay payment integration. Other work includes TapIT, my own hospitality SaaS, and InfinX AI Office, an internal AI-assisted business application running in Docker. CivicAI is a working demo, not a live client deployment.

I have 20+ years across IT, web development and digital marketing, and run InfinX Kft., a Hungarian EU company. I also offer AI API and n8n workflow integration, and manual testing of AI chatbots and apps: prompt checks, output review and reproducible issue reports.

Additional services: graphics with Photoshop, Canva, CorelDRAW and AI image tools; video editing with Wondershare Filmora and CapCut; and AI-assisted English-to-Hungarian localization with native Hungarian review. These are separate services, not part of every web project.

Fully remote, written and asynchronous communication. My English is basic to conversational; I use AI to help with writing. Hungarian is my native language. No live calls or emergency 24/7 support. I reply within one business day. Scope, price and delivery are agreed before work starts.

Role: Web application developer.

InfinX AI Office is an internal AI-assisted office and business management application running in Docker. I developed it for internal use. This case study shows demonstrable functions without confidential data. It is not an external client deployment or proof that n8n is part of the system.

Role: Product owner and web developer.

TapIT is my own SaaS product for the hospitality sector. I work on the product and its web application. This case study presents my own product work, not a paid platform contract. It does not claim customer numbers, revenue or third-party endorsements.
