Handover complete ✓The ugly truths
Can one person really carry this?
Ten years in product and trading systems, plus AI collapsing what used to take a team — architecture, code, tests, deploys — into one person's pipeline. What you save is coordination overhead, not the work itself. Don't take my word for it: every case's domain can be opened and checked right now, and each one links to a full write-up.
What if you disappear halfway?
Real engagements are covered by a signed contract — deliverables, acceptance criteria, and payment milestones are written down, not promised verbally. The build is paid by milestone, and every milestone ships a version that runs and deploys on its own, not a half-built fragment. Stop at any stage and what you have doesn't disappear.
Who maintains it after handover?
Handover means full code, deploy access, docs, and a walkthrough — enough for you or your team to run it independently. Need ongoing support? It becomes a monthly embedded engagement you can pause or end anytime.
What if you don't like the prototype?
Before development starts, the prototype gets revised until you're happy — at no extra cost, since the diagnostic fee already covers everything from requirements to a finished prototype. Paid, milestone-based development only begins once you sign off on it.
Come with a problem. Forty minutes later, you'll have a judgment.
Whether it's worth building, how long it takes, and roughly what it costs. Even if we don't work together, the judgment is still yours.
