Questions before we start

Anything else, ask on WhatsApp or by email.

Do I need to get on a call?
No. Most projects run entirely over email or WhatsApp with written updates. If you prefer a call, we can do one.
How do you price projects?
Every project gets a fixed quote after I understand the scope. You know the full cost and timeline before anything starts.
Do you work with clients outside India?
Yes. I work with businesses in India and abroad, and adjust working hours for overlap where needed.
Can you work with my existing website?
Yes. I can fix, speed up, or extend an existing React, Next.js, WordPress or PHP site, or plan a migration if that makes more sense.
Do you offer support after launch?
Yes. Monthly care plans cover monitoring, tracking checks, fixes and small changes.

Have a website or lead problem to fix?

Tell me what you are working on. You will get a clear written plan and a fixed quote, no sales call required.
