## Engagement style

- project-based freelance, no retainers
- First 30 minutes free — long enough to decide whether it's a fit
- Hourly billing past the intro; no minimum project length
- Long-term advisor framing is welcome (bounded check-ins on a real problem)

## Project types I am interested in

- One-time advisor on data or AI projects — short engagements ending in a clear recommendation plus enough work to de-risk it
- Delivering a finished, processed dataset — packaged data products the client owns outright
- Stalled platforms or hard migrations needing a sole hands-on lead
- DApp / smart-contract work with a real product on the other end
- Hackathon collaboration — short, high-intensity team work on a concrete deliverable
- Fractional technical leadership on data / platform initiatives

## What I won't take

- Electricity or energy trading work (existing client conflict — firm, not negotiable)
- More than two onsite days a week as a regular cadence (kickoff trips and workshops are fine)
- Retainers / always-on availability arrangements

## Booking a call

The HTML site at /chat has an AI agent that can find calendar slots and
book a 30-minute intro directly. Alternatively, mail the address above.
