About

Orlando Wong is a highly skilled software engineer with over 5 years of relevant experience in the field. He currently works as a Software Engineer at doc.ai, where he has been instrumental in developing the Biometric Passport, a React Native app with around 1000 DAU from the ground up. He has also developed an edge genomic data analysis SDK, which includes a performant in-house probabilistic algorithm based on allele frequencies in a sample of populations and expectation maximization. He has improved performance ten-fold and reduced battery usage in half by refactoring the file chunker into native code and migrating to Realm. Orlando is also a core developer for an ETL React app for their AI/ML pipelines, where he rewrote a Vue app into React with improvements to page load times by using client-side caching. Orlando has architected and developed a robust background task job queue module for their internal React Native apps, which reduces their lost events to 0 by guaranteeing delivery of an event to their backend regardless of the backgrounding, disconnects, or crashes. He is proficient in React/React Native/Typescript/RxJS, Python, and Docker, and has a deep understanding of AI, ML, ETL, Backend, and test. Prior to working at doc.ai, Orlando worked as a Software Engineer at 10x genomics, where he honed his skills in software development. He has also worked as a Software Engineer Intern at groupmuse, a platform for organizing classical concerts. During his time at groupmuse, Orlando collaborated with a team of six to work on the Android and iOS app. He refactored components across over 20 files to follow reusable design patterns for maintainability, reducing verbose and repeated code. He also fixed various issues and UI bugs and implemented features to improve performance such as lazy page loading. Orlando increased test coverage by 60% by introducing end-to-end testing with detox and set up a robust native error handler and reporting with Raygun, which allowed them to capture and respond to several critical bugs immediately. Orlando holds a B.S. in Environmental Toxicology from the University of California, Davis, and a Certificate in Computer Science from City College of San Francisco. He also completed a Full Stack Software Engineering course from Rithm School and a Molecular Biology course from UC Berkeley Extension. Orlando's tech stack includes Software Engineering, React Native, Typescript, Python, Postgres, AI, Docker, ML, ETL, Backend
