Codex & OpenAI
GPT-5.3-Codex for extensive software engineering tasks, GPT-5.2 and the Responses API for AI agents and automated workflows. I also use the Agents SDK, MCP, structured outputs, purpose-built tools and clearly defined human approvals.
KI Consulting Swiss
AI that works.
In real operations.
I combine leading AI models with reliable software architecture — from coding agents and multimodal applications through to stable operations.
From model to solution.
A powerful model is only the beginning. I select the right model for each task, develop the product logic and bring the solution into reliable operation.
AI models / 2026
The right model for every task.
Not every task needs the same model. Architecture, quality, cost, data protection and usability determine the choice.
Anthropic Claude
Claude Sonnet 5 for fast, multi-step agent tasks and Claude Opus 4.8 for demanding analysis, architecture decisions and code reviews. I use both with clear context boundaries, quality checks and MCP tools.
Google Gemini
Gemini 3.1 Pro for complex multimodal tasks, Gemini 3.6 Flash for responsive applications, and Nano Banana 2/Pro and Veo 3.1 for image and video production.
Higgsfield
A platform for visual production: Soul ID and Cinema Studio use models including Seedance 2.0, Kling 3.0 and Wan 2.7 for video, plus Flux.2 Pro, Nano Banana and GPT Image for still images.
Selected work
Practice over promises.
In these products, I combine AI with proven software engineering, reliable data and a clear task for the people using it.
Rabattli
A Swiss mobile application for promotions and prices, bringing data collection, semantic search and a production-ready application into one system.

How I work
From idea to operation.
My work does not end with a recommendation. I develop the solution together with the team — technically sound, commercially clear and through to reliable operations.
- 01
Clarify the task
We clarify the need, available data, risks, quality target and measurable value before selecting a model.
- 02
Develop the solution
I combine models, knowledge retrieval, tools, safeguards, the user interface and existing software into a solution that can be verified.
- 03
Operate reliably
Quality measurement, cost, response time, monitoring and human control are set up so the solution works in everyday operations.
