# Albert Fan > Software Engineer at Opera Event Location: San Leandro, California, United States Profile: https://flows.cv/albertfan I'm a backend/full-stack software engineer who loves to write MongoDB queries, which helped me achieve a 60% load time reduction by transforming a slow, data-heavy page into a responsive interface. I have multiple years of working experience at a startup with a small engineering team, where I developed a strong sense of code ownership, fast-paced development, and an ability to quickly learn on the job. My career goal is to join and contribute to a mission-driven organization making a positive social impact. I would also like to work as a backend developer for education, health or finance tech.
