Responsibilities & achievements
I developed reusable and scalable components using React, ensuring consistent code quality and adherence to project requirements. Additionally, I implemented efficient state management solutions using Redux, Redux Saga/Thunk, or Context API, optimizing data flow and application performance. Collaboration with UI/UX designers and product managers was a key aspect of my role, as I worked closely with them to translate requirements into high-quality user interfaces, with a strong focus on usability and accessibility. In terms of integration, I seamlessly integrated frontend applications with backend services through RESTful APIs, GraphQL, or Apollo Client, ensuring smooth data communication. To ensure the robustness and reliability of our applications, I conducted extensive unit, integration, and end-to-end testing using Jest, Enzyme, React Testing Library, and Cypress. A notable aspect of my responsibilities involved spearheading A/B testing initiatives using Google Optimize, aimed at enhancing website performance and boosting user engagement. This involved close collaboration with product managers and designers to conceptualize test hypotheses and establish clear success metrics. I then implemented a variety of A/B tests through Google Optimize, crafting diverse variations of web pages, features, and content to effectively evaluate user responses. Post-implementation, I conducted comprehensive analysis of test outcomes, extracting valuable insights to optimize conversion rates and elevate the overall user experience. Furthermore, I played a pivotal role in cross-functional teamwork, facilitating the prioritization and seamless integration of test findings into actionable strategies aligned with organizational goals.
