Open to new opportunities

Hi, I'm
Nico Rimmele.

Technical Architect & De-facto Head of AI, virtual7 GmbH. Technical architect for a 60-person customer project and, separately, entrusted with an informal but company-wide mandate as virtual7's go-to person for AI. I drive AI transformation hands-on — with an 80% win rate on technical presales, multiple AI workshops across the company, and a clear eye for where AI genuinely moves the needle.

"I test what's actually possible with AI myself before I ask a team to bet on it. I find the best solution together with smart people, not the most comfortable one."

About Me

You're reading an AI system. This portfolio parses job postings, matches them against my real experience, and rebuilds itself into a tailored profile per application — most recently for a role at Orcrist Technologies. Same agentic workflow I use to ship production RAG systems.

Most organizations either bolt AI onto old workflows or wait for the perfect strategy before starting. I test what's actually possible myself first — including on my own AI server at home (RTX 4070 Ti, locally hosted Qwen models, autonomous Hermes agents via LiteLLM) — before I ask a team to bet on it.

As Principal Technical Consultant at virtual7 GmbH, I'm the technical architect for a ~60-person customer project — and, separately, hold an informal but company-wide mandate as virtual7's go-to person for AI. Virtually every company-wide AI question ends up on my desk: from RAG rollout to AI workshops to technical presales (80% win rate on public-sector tenders).

The best solutions rarely come from one person alone; I work them out with the team. That's also why I share what I learn publicly, including on my YouTube channel KImitOtterKiesel, which explains AI topics comic-style for beginners and kids. If I can explain agentic AI to an eight-year-old with a comic otter, I can explain it to your board.
