With a comprehensive range of skills including an in-depth understanding of React.js and Google Maps API, I bring to the table a track record of success in designing and implementing custom mapping features. I am well acquainted with your project requirements of displaying specific locations on a map with personalized markers, pulling data from your Prisma database, and calculating trip distances and durations using an autocomplete feature. This is commensurate with my extensive experience in the power couple of React.js and Google Maps API.
Moreover, my proficiency in updating real-time data will ensure that the changes made to user inputs are promptly reflected on the map as well. In addition to providing an excellent integration service, I take great pride in delivering clean, efficient code that is both maintainable and scalable - qualities that are integral for a project like yours. Having worked on similar projects before, I understand the challenges that can arise while integrating third-party APIs into existing projects, but be rest assured, my proactive problem-solving abilities are well-honed to tackle them.
