Projects

What I'm building, and why each one exists

Six things, all live, all linked. Some are further along than others; one is a closed alpha. There are no revenue figures on this page. When I publish numbers they go in an article with the date attached.

  1. RotorCards

    PDF quick-reference guides for DJI drone pilots.

    A one-product digital store: PDF quick-reference guides for specific DJI drones. Vercel for hosting, Stripe for checkout, GitHub for source. Blog topics come from Google Search Console queries, so each post answers something people already type into Google.

  2. Stronghold Precision Aerials

    Drone services company I run with my wife.

    The drone services company my wife and I run together. This is the field-work side of the drone business: the flying, the clients, the deliverables.

  3. Flycensed

    FAA Part 107 drone pilot exam prep.

    A study app for the FAA Part 107 remote pilot exam, the certificate required for commercial drone operations in the US. It sits upstream of the drone services business.

  4. AZ Land List

    Vacant-parcel data for Arizona land investors.

    Vacant-parcel data for land investors, starting with the Cochise Land Owner Pack. Rural county records are public but awkward to work with; this packages them into something an investor can actually use.

  5. PlotNode

    Digital twin for rural land.

    Upload drone orthomosaics and meshes of a parcel and place structures on the real 3D terrain. Built for the question every rural owner-builder faces: where on this land does the house, the shed and the solar array go.

  6. IsoKron

    Closed alpha

    AI agent substrate. Closed alpha.

    A typed-graph substrate for running AI agents. It is in closed alpha and is the most speculative thing on this list.

Open-source pieces, when I release them, land on GitHub under rafe-walker.
