AI Automation, Web and Mobile Development

AI Automation for Businesses

My current main venture: at nowa.dk I install AI automation in businesses at fixed prices — an AI automation audit, single-workflow installs (mail triage, content pipelines, autonomous task agents) and ongoing operation. The daily articles on this very site are written and illustrated by one of those automations, and you can watch an autonomous kanban agent work a real task at cases.grn.dk. The site is in Danish — English version at nowa.dk/en; web and marketing agencies have a dedicated page at nowa.dk/bureauer.

Freelance

I help companies solve IT problems with automated workflows and AI-assisted solutions — from one-off scripts to full web and mobile applications. Recent work is written up as case studies, and the mobile side lives as interactive Flutter case studies with source code at flutter.grn.dk.

The toolbox behind it: Laravel and Drupal, Flutter, Python and Bash on Linux servers (LiteSpeed, Nginx, Apache), and APIs from Cloudflare to Binance. Explore my services and my CV to learn more.

Selected Projects

  • Technical management of SEO sites — DNS, Linux server management and optimization — at seo-butler.com.
  • My mother's veterinary clinic in Silkeborg, Denmark: BalleDyreklinik.dk, including a journaling system for veterinarians.
  • Ideahunters — crowdsourced idea platform: you have a problem, we give you ideas. Rebuilt and running on Drupal 11.
  • Vegan Camp Thailand — grow-your-own-food permaculture project in Thailand, plus the vegan YouTube channel Plant Sugar.
  • Crypto and stock trading robots — low-risk strategies, built and backtested in Python.
  • Joined forces with my brothers at NowaTech — check out the portfolio.

Short Intro

My name is Grzegorz Nowak (Greg) and I live in Li, Lamphun, Thailand. I am specialized in IT architecture and in solving small and large IT challenges, with a master's degree in logistics (cand.merc.logistik) and a soft spot for the space between business and IT — business needs can often be met with standard solutions, which reduces the cost of complex systems and configurations. I have been building online projects since 1997, and grn.dk has been registered and active since 2004.

P.S. Find useful information at logistikforum.grn.dk and at the Dried Fruit and Chaya organic farm in Thailand, InLi Kasat Farm — sites run on Drupal, one of my favorite web platforms.
