Profile bio
About Matthew Kao
Hello, My name is Matthew Kao, I am a fresh graduate who majored in Computer Science at the University of California, Berkeley. With a year of experience in mobile app development and a deep passion for technology, I have had the privilege of leading innovative projects that push the boundaries of user experience and engagement. As a Lead App Developer at DBRIEF.AI, I spearheaded the creation of the Dbrief.AI mobile app, leveraging my expertise in Dart and Flutter. My role encompassed not only development but also UI design, where I employed Figma to craft visually captivating interfaces while incorporating user feedback to enhance usability. My architectural skills shine through in the synchronization between the application and backend API, driving dynamic content updates and a 15% growth in daily active users. Leveraging Firebase's real-time database capabilities, I ensured the application's responsiveness and real-time information delivery. One of my proudest achievements was engineering 'Tinder-style' swiping features, boosting user engagement by 20%. Additionally, I guided and mentored a team of 4, fostering agile methodologies and cross-functional collaboration to ensure on-time project delivery. As the Founder of Cryptok, I co-founded a web3-based Video Platform that tokenizes user engagement, resulting in a 10% decrease in app crashes. I implemented Solidity for backend smart contracts, achieving seamless and tamper-proof transactions and a 15% reduction in processing time. I also conducted successful MVP testing with 200+ students, with over 70% expressing willingness to switch platforms. In my highlighted projects, I've tackled complex technical challenges, from optimizing political candidate visualization in Action Map to developing advanced AI algorithms in Pacman and architecting a highly efficient Scheme interpreter. I am passionate about pushing the boundaries of technology and delivering impactful solutions.
