Developed an internal CRM interface for managing nationwide online deliveries using React.js and Vue.js. This robust system handled daily active usage by thousands of employees and processed up to a million orders each day without issues- Utilized TanStack Query and RTK Query to reduce server requests and introduce additional data caching, resulting in a 70% decrease in unnecessary calls- Applied my expertise in TypeScript, JavaScript, HTML, and CSS to devise more efficient solutions—routinely removing redundant libraries and improving performance. Recently, I optimized a map-based feature by cutting the page load time for hundreds of polygons from 2 minutes to 30 seconds- Leveraged my understanding of Node.js server-side code to identify and resolve issues on both the front end and back end, significantly accelerating error localization- Drew on my UI/UX design background to take on designer tasks when needed. I was responsible for creating the design of the internal chatbot builder tool- Cultivated a strong and supportive internal community at the company. This positive environment even enabled us to rehire an employee who had previously left- Actively participate in our Agile testing process by writing unit tests, which helped boost the project’s effective coverage by 20%- Contributed to the development of a one-hour online delivery system in Brazil for Dia supermarkets.
