Now

What I'm building and learning right now. I update it when something changes; the date is below.

Building

  • An AI support channel at Vibetex

    A customer support channel with LLMs, RAG and semantic search, wired into the existing Java, .NET and Angular systems.

  • A legal product of my own

    AI applied to a problem I know from the inside, from my years in law and at the Bar Association. The name stays under wraps until the trademark is registered.

  • This portfolio and Nox

    Nox now has an MCP server, so any AI assistant can query the site, and a dashboard with cost, latency and question topics in production.

Learning

  • Fine-tuning

    For repetitive tasks, instead of stuffing all the knowledge into the prompt like I did on my first AI project.

  • Structured RAG and embeddings

    Chunking, titles and metadata, hybrid search and how to measure whether retrieval brings back the right passage.

  • Multi-agent systems with MCP

    Agents with one job each (classify, summarize, query, audit), talking through a standard protocol.

  • Guardrails and the OWASP Top 10 for LLMs

    Defenses in code and in the prompt, and how to test them automatically.

  • Systems Analysis and Development

    Associate degree, expected to finish in 2027.

Direction

  • From full-stack to AI Engineer

    And, in the long run, AI architect: designing AI systems you can audit, measure and maintain.
