Privacy by design
Credentials stay isolated inside the platform. The model only ever sees the question and the answer, and every operation is logged.

I build software that talks to your company's data.
Since 2020 I have been building for the web: ERP-integrated e-commerce, operations dashboards and open source libraries in TypeScript. Today I do AI engineering at Dulyx: agents, RAG and the harness that connects models to company systems without ever exposing credentials.

Founder
Dulyx
A layer between AI and a company's systems. The model asks in natural language, Dulyx queries the ERP, CRM or API at the source and returns only the answer. Credentials never reach the model.
Changes need approval
Queries run straight through. Any change to an order, product or stock level becomes a proposal that a human has to confirm.
Where the company already is
Runs on the company website and in any MCP-compatible assistant, with agents per area: sales, finance, support and logistics.
Less data, lower cost
Records are reduced before they reach the model, billed per conversation with no per-seat pricing.
AI Engineering
Models are the easy part. The work is everything around them.
At Dulyx I build the infrastructure that makes an agent trustworthy inside a company: well-defined tools, data reduced before the model, human approval for every change and a full trace of each operation.

Agents with tools
Agents scoped per area, each seeing only the tools of its domain. Every tool has a clear input and output contract, so the agent never invents data: it queries for it.

Harness with a human in the loop
A runtime that routes calls, applies guardrails and turns every change into a proposal. Nothing moves in the ERP without a person confirming, and all of it is recorded.

RAG and hybrid retrieval
Retrieval over documents and catalogs combining lexical, phonetic and embedding search. CAISS was born here: precision on product names, codes and abbreviations, exactly where vectors alone fall apart.

Context reduction
Records are trimmed and summarised before reaching the model, with metadata that flags when a result set came back truncated. Fewer tokens, lower cost, less hallucination.

Ready-made integrations
Twenty-plus connectors for enterprise systems and channels, exposed as MCP servers for Claude, ChatGPT and other compatible assistants.

Evals and observability
Every conversation leaves a trace: tools called, data returned, decisions taken. That is what makes it possible to measure quality, compare models and improve prompts with evidence.
