Upgrade custom text input format from Drupal 6 to Drupal 8

For upgrading a Drupal 6 application into Drupal 8 I need a developer, who is able to upgrade custom text input format from Drupal 6 to Drupal 7. The input format consists of several Filters: Filters which already have Drupal 8 equivalents • Footnotes Filters which need to be upgraded • Pearwiki filter with (customised) Mediawiki format. • Wikilinks with wikitools • DruTeX • Pathologic • Table of contents • Simple custom filter (Drupal 6 module) What I need -------------------- Feature + custom module(s), which will after enabling offer the exact equivalent of the text input format functionality presented in legacy Drupal 6 application. What you get to start with -------------------------------------------- Working Dockerised Drupal 6 application, containing that text input format. What you Do NOT get ------------------------------------ The Dockerised application does not contain LaTeX for Drutex. It is your task to actually enable Docker LaTeX container and make it work with your module as the Remote Latex Renderer as defined in legacy Drutex module.
