# Kieron Ong > Software Engineer @ Headway Location: Brooklyn, New York, United States Profile: https://flows.cv/kieron As a Computer Science senior at the University of California, Berkeley, I have honed my skills in full-stack development through rigorous academic challenges and hands-on internship experiences. My journey so far has been a blend of technical growth, team leadership, and a relentless pursuit of innovation, particularly in the realms of React development, automated testing, and cloud services with a focus on Amazon Web Services. Core Skills & Technologies: Languages & Frameworks — Extensive experience with Javascript, Typescript and Python, complemented by practical knowledge of Go, C and Java. Frontend Development — Proficient in React and Redux with track record of rapid development of responsive user interfaces, with strong command of HTML/CSS and design frameworks. Testing & Observability — Developed robust testing frameworks using Jest and Appium, and implemented observability solutions with Amplitude and Looker. Cloud Computing & DevOps — Expertise in AWS for building scalable serverless architectures, alongside proficiency in MongoDB and BigQuery for robust data management and performance optimization. Academic Pursuits & Projects: Through my coursework, I have gained a solid foundation in database design, AI, and efficient algorithms, which has translated directly into my project work and internships. My project, Explr.ai, a prize winner at CalHacks 10.0, demonstrates my ability to leverage AI for practical solutions, while my full-stack development roles via UC Berkeley Codebase showcase my commitment to real-world applications. As I approach the completion of my degree, I am eager to continue growing in early career SWE roles that allow me to contribute to transformative projects while also expanding my expertise in emerging technologies.
