To be able to meet creative needs of your project and finalize/fullfill your project in the best possible way, i would like to be involved in the project from earliest possible stage, preferably pre-production.
That is a good starting point to allow me to understand the goals of the project and with that to avoid unwanted surprises.

During the editing process, i keep in touch with the editor and director and eventually i could provide sounds that would help clarify and enhance the directors vision.

When the picture is locked, the last part of the filmmaking process starts, post production.
