Common Questions
How does a project start?
With a short call or email thread to pin down the problem. Then you get a written scope with a timeline and a price before any work begins.
How do you charge?
A fixed price for well-defined projects, and hourly or a monthly retainer for ongoing work. You know the number before we start.
How long does it take?
Small automations usually take one to two weeks. A full application takes four to eight, depending on scope.
Can you work inside my existing team or codebase?
Yes. Most of my professional work has been in existing codebases, through pull requests and code review.
What hours do you work?
Jakarta time (GMT+7), with overlap for Asia-Pacific and European mornings.
