Hammer is an app I've been building as a personal project to help people learn a foreign language in a more efficient and fun way. Try it at https://hammer.app

• Developed a Single-Page Application using JavaScript/TypeScript with a custom VanillaJS React-like framework, packaged into an app for Android and iOS with Apache Cordova

• Created the backend with Node.JS with Express and a Postgres database running on Google Cloud Platform, and Firebase Authentication/Hosting

• Invented a unique system for managing flashcards, designed the UI, and created feature specifications and mockups to direct another engineer

• Released the Hammer app, which has helped more than 1000 users learn a language

• Led technical teams that developed core applications including Bellus3D FaceApp, which captured 3D face geometry for more than 100,000 users (Java, JavaScript, Swift)

• Created and securely managed a cloud service containing more than 250,000 face scans

• Directly recruited, trained, and supported multiple software engineers

• Built prototype apps to demonstrate Bellus3D technology at trade shows including CES

• Drove initiatives to improve customer messaging with copywriting, UX, and website redesigns
