Location: Greater Chicago Area, United States
Profile: https://flows.cv/cynthial

I am a Front-End Developer with 3+ years of experience and a passion for creating visually appealing and accessible solutions for the web. I am constantly staying on top of current trends such as hooks and Typescript React, styled components, and various testing libraries. 

I have experience in creating reusable component libraries in Adobe Experience Manager, as well as creating single page applications with React and Redux. 

My work has given me a strong aptitude for collaborative design discussion, zeroing in on details, and following through with delivery of ideas and answers. I enjoy 1:1 mentoring, team collaboration, and independent brainstorming to pursue creative solutions and new innovations. I love to learn on my own and from others, and won't hesitate to dive into unknown waters. 

Experience with:
HTML5 / CSS3 (SCSS), Bootstrap, JavaScript / jQuery,  AJAX / JSON, React, Redux, React Native, Git / GitHub, Node.js, Express, Jest/Enzyme, Typescript React, Emotion, TDD, AEM, Adobe Experience Manager
