02 — Method
Method
Four principlesBusiness first
I understand your domain before talking technology.
Hybrid AI
Business rules do most of the work; an orchestration layer decides when to call a model.
You stay in control
The code and data belong to you.
Tools under control
AI helps with repetitive work, code review, and bug finding; architecture and validation stay in my hands.
Interactive demo — illustrative simulation
Hybrid AI in practice.
Pick a scenario. Items flow through the system; the AI model is invoked only when business rules are not enough.

Client reviews
VerbatimSimon far exceeded our expectations, both in the quality of his work and his commitment to the project. As a result, we decided to start a new engagement with him right away.
He is a professional who adapts well and explains things—not in developer jargon, but in language a user at their screen can understand.
Strong understanding of our needs, good communication, and results delivered. The app runs flawlessly. Our clients and we are completely satisfied.
Very happy with the work and proactive suggestions […] Excellent follow-up with app improvements after delivery.
Despite the challenges, he built the plugin I needed, plus practical integrations that were not in the spec.
Simon built our website, understood our needs perfectly, and is very responsive. For us it is essential to have an expert who understands us and guides us.
