Growth Strategist, Performance Marketer, Developer, Data Scientist and Unicorn.
Hi, I'm Georg, a London based Growth Hacker, Data Scientist, Developer, and most recently AI Engineer with 14 years of experience and a hands on approach to turning ideas into thriving businesses. I've helped startups, ecommerce stores, and SMEs achieve fast yet sustainable growth through data driven strategy and practical execution. What sets me apart is simple: I don't just talk the talk, I walk the walk. I execute directly, cutting out inefficiencies and delivering measurable results. I primarily offer my services on a commission basis, effectively covering my own cost, because that's how confident I am in what I do.
Everyone is talking about AI agents in 2026, but most people still confuse them with chatbots. The difference is not cosmetic. Agents book flights, purchase groceries, manage inventory, and negotiate with other agents, all without a human clicking a single button. This post explains what actually changed, shows real examples of agents in action, breaks down the protocols making it all work, and explains what it means if you build ecommerce on Rails and Solidus or run a SaaS.
Agentic AI is the biggest shift in ecommerce since the smartphone. AI agents that autonomously manage inventory, handle customer support, route orders, and optimise pricing are already reshaping how online businesses operate. But what does agentic actually mean in plain English? How is it different from a chatbot? And how do you build these systems on Ruby on Rails and Solidus? A practical guide from someone who is building this right now.
A technical but accessible walkthrough of adding ML-powered product recommendations to Solidus, the open-source Ruby on Rails ecommerce framework. Covers three recommendation approaches (collaborative filtering, content-based, and hybrid), complete with Python ML scripts, full Solidus/Rails integration code, event tracking, cold start handling, A/B testing, GDPR compliance, and the honest limitations and pitfalls you'll hit along the way. No black boxes - every piece is explained and every trade-off is named.
A deep dive into Test Driven Development and Behaviour Driven Development in Ruby on Rails. What they are, how they differ, why they exist, and how they prevent the costly bugs that plagued the old way of building software. Includes a detailed comparison of RSpec, Minitest, and Cucumber, practical examples from building Auto-Prammer.at on Solidus and the Regios fintech SaaS powered by GrowCentric.ai, plus a best practice guide for using AI tools like Claude to supercharge your testing without losing control.
Europe depends on US tech for 85% of its cloud infrastructure. With Trump's trade wars and the CLOUD Act threatening data sovereignty, it's time to switch to European alternatives. Here's what I use instead and why you should too.
The NIS2 Directive is now active across the EU, covering SaaS providers, cloud platforms, online marketplaces, and digital service providers. Fines reach up to 10 million euros. If you run a SaaS platform or ecommerce business serving EU customers, here is what you need to know and what you need to do.
