Michael Ninh

AI Engineer · Applied AI · Product Builder

I build AI systems that turn complicated workflows into clear, useful tools. My background combines hands-on engineering with founder, product and operations experience. I am strongest when I can go from a messy problem to a working product, test where it fails, and improve it with real users.

01 · Selected work

Live research tool

GitLaw

Find and inspect relevant German federal law with traceable sources. The current Mietrecht pilot turns user-found retrieval failures into permanent regression cases; broader lawyer task-success validation is still pending.

Working closed beta

SafeVoice

Turn online-harassment text or screenshots into a structured, reviewable evidence package. The end-to-end flow works; important classifier failures are documented and broad real-user validation is still next.

Engineering prototype

Digital Worker Factory

A reusable pattern for AI workers that must show evidence, expose failure and ask a human before consequential action. Public scenarios and the current reliability suite are synthetic; a real shadow workflow is the next proof.

GovTech prototype

PrüfPilot

Review documents against versioned rules and show what is missing before a human decision. The PDF intake/extraction core works; the public reviewer cases are synthetic and the system is not deployed in an authority.

03 · Experience

Founder & E-Commerce Manager · RYUS UGSep 2018 – Mar 2025 · Berlin

Built and operated an Amazon business end to end across sourcing, logistics, fulfilment, listings and customer support; turned repeatable operational work into clearer processes.

Service & Operations Manager · Transit RestaurantsAug 2021 – Sep 2024 · Berlin

Coordinated daily operations for 8+ staff, up to 150 covers per day and delivery workflows; resolved bottlenecks under peak-service pressure.

Product Manager / Business Development · everphone GmbHJul 2019 – Sep 2020 · Berlin

Scaled omnichannel e-commerce across marketplaces, website and B2B partners; managed acquisition channels and used customer feedback to improve positioning.

AI Engineering & Software Engineering · MasterschoolOct 2025 – Jun 2026

Full-stack software engineering, extended through hands-on work in LLM applications, RAG and agent systems.

The next proof
Real users. Real corrections. Measurable outcomes.

I have built quickly across several domains. The next step I care about most is putting the strongest systems in front of target users, learning from their corrections and turning those failures into better products.
