In my role as a proficient full-stack developer, I successfully constructed a React Redux web application alongside a Progressive Web App (PWA) leveraging Node.js/Koa middleware. This comprehensive platform catered to the reservation of movie and concert tickets, encompassing elements such as reviews, trailers, and events. Additionally, I implemented an innovative configuration-based workflow that seamlessly integrated pre-existing booking processes while proficiently managing the legacy PHP and jQuery-based system. Emphasis was placed on optimizing the web pages for expedient schedule access and facilitating seamless bookings, all achieved through a streamlined and concise user journey.

I possess extensive experience in seamlessly integrating React front end with payment service providers (PSPs) across diverse countries. In addition, I have successfully developed self-service upgrade functionalities allowing current customers to seamlessly transition to premium packages. Moreover, my expertise lies in crafting customized monthly subscription flows, optimizing conversion rates. Furthermore, I have spearheaded the creation of an exclusive add-on marketplace, enabling customers to purchase additional features without necessitating an upgrade to their existing packages.

I spearheaded the development of a cutting-edge microlending and maintenance web application employing the React framework. By devising a shared architecture capable of serving numerous projects, I facilitated seamless loan management for clients across diverse geographical regions. At the helm of a proficient team of five, I oversaw the design of the client-side application utilizing both React and Node.js middleware. Alongside, I successfully integrated structured logging mechanisms and adaptable lambda functions for proactive alerting, driven by meticulous monitoring of microservice logging metrics.
