How we work

Fixed-scope project

Milestone contract: scope doc → 50% kickoff → build demos → 30% at beta → 20% on handover. You own the repo and docs from day one.

FAQ

Do you do hourly work?

No — fixed scopes and retainers only. Hourly penalizes efficiency. You get a written scope, fixed price and dates before we start.

Who owns the code?

You do, on final payment. MIT-licensed starter included where relevant; secrets and keys never leave your vault.

Payment terms?

50% kickoff, 30% beta, 20% handover via bank transfer or stablecoin (USDC/SOL/SUI). All prices are in naira with dollar equivalents shown; NGN invoices available for Nigerian entities.

How fast can we start?

Usually 1–2 weeks out. Rescue sprints can start faster if the repo and credentials are ready.

Do you maintain after launch?

Yes — 2-week bugfix window is included. After that, a monthly retainer covers fixes, deps, small features and monitoring.

NDA / contracts?

Happy to sign your NDA or use a simple milestone SOW. Everything (scope, price, dates, IP) is in writing before kickoff.
