Tailored AI Efficiency

About Me

Meet Your AI Consultant

My fascination with AI is not driven by hype, but by scientific rigor. During my M.Sc. in Data Science at TU Wien, I specialized in RAG architectures and NLP, realizing early on that true efficiency requires deep technical engineering, not just standard tools.

My background in Credit Risk Modeling (Banking) and Big 4 Consulting taught me that precision is non-negotiable. Today, I combine this technical excellence with a lean, iterative approach, delivering robust, research-backed systems with startup speed.

I believe in radical transparency. Whether it’s regarding data privacy (GDPR), system architecture, or pricing models: You should always know exactly how your investment works. My goal is to turn AI from a buzzword into a secure, transparent, and measurably efficient asset for your company.

How RAG Delivers Precision

A RAG system, engineered with LangChain

01 Indexing

We load your documents, clean the text, and split it into small pieces. Each piece is turned into a numeric vector so the system can understand its meaning. All vectors are stored safely in a vector database.

02 Query Embedding

When you ask a question, your query is also converted into a vector. This allows the system to compare your question with the meaning of your documents.

03 Similarity Search

The system searches the vector database and finds the most relevant document pieces. These are the chunks that best match the meaning of your question.

04 (Optional) Re-Ranking

A deeper AI model reviews the top results and sorts them by real semantic quality. This improves accuracy, especially when you have many documents.

05 Augmented Prompt & LLM Answer

The best-matching text pieces are added to your question. The LLM uses this combined context to generate a precise, grounded answer.

IT-Infrastrucute

GDPR-Compliant Infrastructure

The Starter Package

01 Secure Connection

Your browser connects via a high-security encrypted tunnel (TLS 1.3). This ensures your request is fully protected while traveling to our servers in Germany.

02 Isolated Routing

Our security gateway identifies you and directs the traffic straight to your personal, isolated container. This strict separation guarantees that your system is completely cut off from other clients.

03 App & Logic

Your dedicated application processes the request exclusively within your private environment. It acts as the secure "brain" that manages your data access and search logic.

04 Private Vector Storage

Your documents are stored in a dedicated database (Chroma) directly on the server disk in Germany. This "data vault" is encrypted and accessible only by your application instance.

05 Anonymous AI Inference

To generate the answer, we send only relevant, anonymized text snippets to the enterprise AI model. The provider is contractually bound to delete this data immediately after processing (Zero-Retention Policy).

The Professional Package

01 Corporate Single Sign-On

Employees access the system using their existing company credentials (e.g., Microsoft 365 or Google Workspace). This ensures seamless integration into your IT security policies without needing new passwords.

02 Dedicated Private Server

Your entire infrastructure runs on a dedicated Virtual Private Server (VPS) reserved exclusively for your company. Unlike shared hosting, this guarantees maximum performance and total physical isolation of your data.

03 Advanced Logic & History

A powerful backend (FastAPI) orchestrates complex workflows and connects to your internal tools. An integrated database (PostgreSQL) securely saves your chat history, allowing you to revisit past conversations anytime.

04 High-Performance Cloud

To handle large document archives, we utilize a specialized enterprise vector database (Pinecone EU). This hybrid-cloud setup allows the system to search through thousands of documents in milliseconds with pinpoint accuracy.

05 Smart Privacy Filter

Before any text leaves your private server, our active privacy shield automatically detects and masks sensitive personal data (like names or IBANs). The AI provider receives only anonymized context to generate the answer.

FAQ

Frequently Asked Questions

How do you handle data privacy and GDPR compliance?

We ensure security through a tiered privacy model: By default (Starter), we guarantee GDPR compliance via encrypted hosting in Germany and strict zero-retention agreements with enterprise API providers. The Professional tier adds an active Privacy Filter (PII Masking) that automatically anonymizes personal data before it leaves the server. For strict sovereignty requirements, we can also deploy fully isolated Local LLMs that run entirely on your own infrastructure.

Are there any ongoing costs or licenses required?

How does this differ from using ChatGPT directly?

Can multiple employees use the same assistant?

Can we safely include customer or internal data in prompts?

Do we always get the newest GPT version?

How are data updates handled?

How do I access my private assistant?
