Four steps, no surprises
Every project runs the same way, so you always know what happens next and what you get at the end of it.
Scope
1–2 daysYou message me the problem, the constraints, and the budget, and we work through it in a short back-and-forth. You leave with a clear view of what is buildable now and what should wait.
Written scope + fixed quote
System design
2–4 daysBefore any code, you get the plan: screens, data model, integrations, and a milestone list. This is where the expensive mistakes get caught.
Architecture doc + milestones
Build
1–3 weeksShipped in tight iterations with a working demo every week. No month-long silences, no surprise scope creep.
Weekly demo you can click
Handover
1–2 daysDeployed, documented, and fully yours. Source access, database guide, and a walkthrough so your team can take it forward without me.
Live system + full ownership
Tell me what you're stuck on.
Get a clear plan, fast execution, and a working outcome without turning the build into months of uncertainty.
