Work Terms

Availability:
I am available for both short-term and long-term projects. My working hours are flexible and can be adjusted to align with your time zone or project needs. I’m typically available Monday to Saturday, with prompt communication guaranteed.

Communication:
I prefer to communicate via Guru’s messaging system, email, or Zoom/Google Meet for project updates and meetings. I respond quickly and keep clients regularly updated on progress.

Payment Terms:
For hourly projects, I require the use of Guru's WorkRoom and time-tracking tools.
For fixed-price projects, I request milestone-based payments and an initial deposit into SafePay before work begins.

Turnaround Time:
Turnaround depends on the complexity and scope of the project. I always strive to meet agreed deadlines without compromising quality.

Revisions:
I offer reasonable revisions to ensure the final result meets your expectations. I believe in clear communication upfront to avoid misunderstandings later.

Client data and intellectual property are treated with the highest confidentiality. I’m happy to sign NDAs upon request.
