Looking for a Code Hero - Property browser extension front & back end

I'm looking for a technical co-founder with experience of development of modern Javascript (think Webpack, NPM, ReactJS etc.) for app development.
PropertyExtra is a platform for house-hunters to get better information about property and neighbourhoods they are looking at, and to be able to better collaborate as couples, families, and business partners.

The product is is delivered via a browser Web Extension front end. Under the hood is a Laravel (PHP) "engine" using AWS infrastructure services (EC2, SQS) and MongoDB for large scale database.

PropertyExtra is currently in MVP state, and not monetising. The aim is to get the product monetising in the next 6 months. The model will be "freemium" subscription-based charging.

I'm looking for someone with some good coding experience who can help me bring some structure and good software architecture to my "MVP" code.
