With a decade of experience in Backend Development, I have acquired and honed an array of valuable skills and expertise that make me an ideal fit for your project. Starting from the core backend languages such as Node.js, PHP, and database management through MySQL and MongoDB, I have had exposure in cutting edge frontend technologies as well, including but not limited to React.js and Express.js.
Notably, my familiarity with Google Maps API, Restful API, Payment Gateways and my proclivity for using third-party APIs offers me an edge when it comes to creating functionalities that enhance the user experience - such as the offline access you require for your PWA. My prior familiarity with JSON and Restful API further allows me to ensure that your PWA could deliver timely push notifications.
Moreover, I possess a deep understanding of responsive design principles which makes me well-equipped to develop PWAs for seamless use across different devices, whether it's a desktop or mobile platform. To back up my claims, I encourage you to look at my profile at https://www.freelancer.com/u/anilk829 to see cases where I designed user-friendly applications whilst also using Firebase in ensuring data integrity. For these reasons and more, I believe hiring me would be both a smart and reliable choice.
