I currently work on many of Centivo's software ecosystem of apps - from the member-facing health insurance plan app (my.centivo.com) to the Centivo Care doctor-patient virtual care app to several other internal tools. The tech stack is generally JavaScript/TypeScript/React/Node/SQL/NoSQL/React Native and an extensive range of AWS services in addition to interfacing with several 3rd party healthcare and medical claim management services.

I worked on Mailchimp's SMS marketing campaigns part of the app as a fullstack engineer. The tech stack I contributed to was JavaScript/React/Jest/React Testing Library/Playwright and GCP/Go/PHP/SQL/Twirp/gRPC. Even though I was strongest on the frontend and had never used Go, Google Cloud, or gRPC before, I quickly mastered these and independently managed Mailchimp's entire stack including adding more gRPC services and endpoints in Go that were covered with unit tests.

I am the creator of LingoMap, a map app for foreigners who cannot read Chinese to use in China. It is a translation of Alibaba Maps (known as AMap and 高德地图). It shows place, transit route, and street names in the original Chinese, Mandarin Pinyin, and English.

Previously called Lost Laowai, LingoMap grew from a simple single page application JavaScript web app started in 2016 to a modern and capable TypeScript React Native Android and iOS app. The app has an established following and user base among foreigners who are interested in traveling in China.

I was mainly a JavaScript/TypeScript/React/Node frontend developer for Binance.com, the international version of the crypto exchange, as well as also had experience developing their backend systems. I was part of 3 major teams working on new user registration KYC (know your customer), KYB (know your business), and integrating web and Android/iOS Binance app end-to-end tests triggered via CICD pipelines.

My role has expanded to help work on more of the company's fullstack projects, mainly working with TypeScript, JavaScript, React, Vue, Node.js (Next.js), PHP and MySQL. Working hard to maintain code quality through merge request reviews, increasing unit test coverage, and as always continuing to learn more about what can go in the many layers of the stack!
