When a developer works the same hours as your team, a question at 10:00 is answered the same morning. Reviews, kick-off calls and small decisions fit into the day instead of waiting for the next one.
I work Monday to Friday, 9:00 to 17:00 CET, from Verona, Italy. That is the same time zone as the Netherlands, Germany, Austria and Switzerland, and one hour ahead of the UK and Ireland.
The way a project starts is the same for every agency. You send the brief, the design and the staging access. I reply within 24 working hours to say whether I can step in, and the estimate, in hours, usually follows within two or three working days. The scope closes before work starts.
I work inside your tools and under your brand. The end client does not need to know I exist, and I sign an NDA if you or the client ask for one.
