How we work together
Four steps with clear timelines. You always know where the project stands.
Intro call
30-60 min
We talk about your company, the problem and what success looks like. No technical jargon.
Proposal and scope
1-2 days
You get in writing what I will build, what it will cost and when it will be ready. No hidden fees, no vague estimates.
Design and build
2-8 weeks
I work in short cycles. You see progress every week and can give feedback at any time.
Launch and handover
1-2 days
We launch the system together and I show your team how to use it. I stay available after launch.
From a client
The company delivered exactly what we described, and more. The system replaced all our paperwork and our managers actually use it every day. We save hours on payroll every month.
