Looking for full/ stack developer or front end developer. London/UK based be better but open to outside UK

Hi. I’m looking for someone who is looking to potentially get involved in a project either on sweat equity or paid for a reasonable sum to help particularly with front end of my start up. In short I’m looking to build a management tool like that of open table for making reservations etc but for the building industry. The management tool will be provided to relevant businesses and will allow them to make listings update availability create invoices etc. If you can help with this please get in touch and I will be happy to discuss further. The management tool is part of a much bigger idea that currently does not exist with a huge demand and gap in the market. Happy to discuss further with the appropriate person. Let’s connect and chat further if this is something that sounds of interest to you.
