Part Time Full Stack developer

I am the founder/director of a long-running boutique tour operator and I need an experienced UK-based full-stack developer to work with on a long-term basis. Work would be on an hourly basis according to business needs and would be a mix of bug fixing and small feature development.

You would need to be available to work on issues 5 days a week, ideally, but there is some flexibility. Total hours per week would probably average 3-5 hours, but there'd be periods where the workload may be higher. You would be working alongside another part-time/freelance developer and would be expected to coordinate codebase updates via GitHub.

Our tech stack is as follows:

MySQL 5.7
PHP 7.4
Laravel 8.7.5
Vue 2.6

Experience working with the Stripe API is a distinct advantage and experience of the Xero API would be helpful.
I'm looking to forge a good working relationship with a developer who has extensive experience of working on a similar tech stack for a small company and dealing with non-technical POCs.

Communication would be via Trello, and we'd expect monthly billing (although weekly billing could be arranged if required).

Please don't apply for this project if you live outside the UK, as we need someone in the same timezone as our office.
