Wordpress Developer to Customize the Events Calendar Plugin

We run a community arts centre and use WordPress with The Events Calendar (StellarWP) and Event Tickets Plus to list about 30-40 events a month. Need someone who has actually worked with this plugin before. Please don't apply if you haven't. Tasks: a) Custom single-event template matching our current theme (Astra Pro) b) Add 3 custom fields: speaker name, venue map link, ticket tier c) Filter bar on the events archive page by category + month d) Fix the timezone bug: since the last plugin update, events show 1 hour off on the front end e) Recurring events should display as one grouped listing instead of 12 separate entries f) Make sure Event Tickets Plus checkout still works after all changes Use a child theme and template overrides only, with no core plugin edits. All work happens on staging first, and we push to live after approval. Please leave short handover notes so our in-house person can maintain it. Staging and admin access will be given once we start. If you've solved this timezone issue before, mention it in your proposal.
