Sebastian in a few words
Seasoned Frontend Developer with a proven track record of designing and implementing responsive, user-friendly web and mobile applications. Specializing in Angular, Ionic, and JavaScript frameworks, I have contributed to diverse projects across sectors such as healthcare, government, and hospitality. My expertise lies in developing custom UI components, optimizing application performance, and integrating complex systems to deliver seamless digital experiences.
I excel in creating maintainable, efficient code structures using tools like SCSS, ensuring consistent and scalable UI designs. With hands-on experience in consuming and optimizing RESTful APIs, I have successfully integrated real-time data features and external services, including advanced functionalities like speech-to-text processing. A strong advocate for Agile practices, I collaborate closely with cross-functional teams and emphasize continuous learning and adherence to coding best practices through code reviews and unit testing with Jasmine and Karma.
