01 /How I work

Four phases, clear handover.

  1. Discovery

    Sketch it together: processes, data, risks. Clear go or no-go.

  2. Prototype

    Functional version on synthetic data. Your production system stays untouched.

  3. Validation

    Feedback loops and integration into your system. Honest performance numbers.

  4. Handover

    Code, docs, live training. Your team carries on.

02 /Proven by data

Demonstrated practice, not promises.
