Senior Care Marketplace

2018 – 2021Commercial · React · Marketplace · Testing

My first product at 104: a two-sided marketplace where carers registered their skills and available hours, each got a profile page, and families browsed and booked them. It carried the parts a real marketplace needs — scheduling, a photo-and-timestamp clock-in, map-based discovery, and reminder emails. It was built in React. It was never replaced by the 45+ job platform — they are two different products; this one couldn't be made to pay for itself, so the company had our team build a new one. The change I'm proudest of here wasn't a feature: the team had no automated tests at all, and by the time I left, a passing test suite was a required step in every pull request.

Key features & challenges

Built map-based discovery of nearby carers with Google Maps, including pin clustering at low zoom levels.
Built the availability UI where carers set the hours they can work, at hour granularity, plus the failure states when a booking couldn't be taken.
Introduced automated testing to a team that had none: my manager raised the idea, I researched the options and led it in, wrote the first Jest and Nightwatch suites, and taught the team to write their own.
Worked with the tech lead to make a passing suite a required step in the pull-request process — changing how the team worked was the harder and more valuable half of it.
Honest about where it landed: coverage was still small when I left, but the gate was already catching real regressions before review.

My contributions

Front-end work on both sides of the marketplace, and the person who brought testing into the team.
Preventing double bookings was handled on the back end; my part was the front-end states around it.
