FAQ

Frequently Asked

Answers to the questions you ask yourself before reaching out.

What's your day rate?
My day rate depends on project complexity, duration, and commitment level. Contact me for a custom quote.
How do you handle the timezone difference?
GMT+4 from Mauritius - I'm online 9 AM–1 PM CET for syncs, then deep work in the afternoon. Most clients find this is an advantage: their evening requests are handled during my morning.
What type of contract do you offer?
Freelance via Prismyq Ltd (Mauritian company). Monthly invoicing, framework agreement. I can also work through Malt for companies that prefer an intermediary platform.
How fast can you onboard?
48h for repo access and onboarding. First PR within the week. I'm autonomous by day 2 - no hand-holding required.
Do you work time & materials or fixed price?
Both. Time & materials is ideal for long-term or evolving missions. Fixed price works for well-scoped projects with clear specs. We discuss what's best together.

Have another question?

I reply within 24 hours, often much sooner.
