Send the rough version.
I will find the shape.

Tell me what you are trying to ship, automate, or untangle. It might be a $99 Technical Advisory Call, a $490 landing page, a $990 AI Pilot, a $1,990 AI Inbox Bot, or the $6,500 Sprint. If it needs Fractional CTO or Bitcoin work, I will say that too.

What you can book me for

Three kinds of work I will actually take on.

Every engagement type has real shipped work behind it. Pick the closest shape, then we will scope the specifics without turning it into a long sales process.

  1. 01

    Start small · primary

    Technical clarity from $99

    Five small starting points: $99 Technical Advisory Call, $490 landing page, $990 AI Pilot, $1,990 AI Inbox Bot, and $6,500 Sprint. The point is to get clarity or ship something concrete first, then decide from evidence whether it deserves more budget.

  2. 02

    Fractional CTO

    Embedded technical leadership

    One to two days a week for pre-Series A founders. Architecture, hiring calls, review, delivery rhythm, and the decisions that get expensive if nobody owns them.

  3. 03

    Bitcoin & Web3 · selective

    Senior BTC engineering

    Pizza Ninjas, Pizza Pets, Project Spartacus, and OrdinalsBot are the background here. I still take Bitcoin work when the team is building something that has to survive mainnet, not just a launch thread.

Small asks I can turn around this week.

Start here

A rough sentence is enough.

Pick the shape closest to what you need and send one line about what you are building. I reply within 24 hours on weekdays; WhatsApp is usually faster.

If we are a fit, I will come back with an honest take, a fixed price, and the next slot I can start. No deck, no funnel, no pitch.

FAQ

Before you ask.

Can I book a call before choosing an offer?
Yes. The Technical Advisory Call is a 90-minute working call for scoping, architecture choices, stack questions, or deciding what to build first. Launch price is $99 USD and includes a short written recap. Book the call on Calendly first; I send the payment link after booking to confirm your slot.
Which offer should I choose?
Start with the smallest shape that proves the work. Technical Advisory Call is for scope and answers. Live in a Day is for one decisive landing page. The AI Pilot is for one small automation in three days. AI Inbox Bot is for repeat customer conversations in the channel you already use. The Sprint is for one full production workflow in 14 days.
What do you need from me before we start?
One clear outcome, access to the stack we are touching, and one person who can answer questions quickly. For AI workflows, useful examples beat long briefs: tickets, leads, messages, product events, docs, or the manual process your team runs today.
Can the $990 Pilot become the $6,500 Sprint?
Yes. If the Pilot shows the workflow is worth expanding, the $990 credits toward the Sprint when you book it within 30 days. The point is to de-risk the larger build with something live, not sell you a throwaway prototype.
Do you still take custom CTO, SEO, or Bitcoin work?
Selectively. The fixed-scope menu is the default because it is faster to scope and easier to buy. Fractional CTO, SEO and AI consulting, and Bitcoin engineering still fit when the problem needs senior judgment rather than a fixed package.
How quickly will you reply?
Within 24 hours on weekdays, usually faster on WhatsApp. If it is not a fit, I will say so directly and point you toward the closest useful next step.
