Experience
Easy-to-use Database Service
An easy-to-use database service I built on AWS to compete with Google Firebase. It uses Amazon DynamoDB as an underlying NoSQL database. The service is recommended for beginner-to-intermediate-level engineers who are unfamiliar with professional databases but prefer to use a database with a web console and API key. Customers can sign up for a free plan with a limited experience and a paid subscription to use the complete services. The service also features multi-tenant and team collaboration.
Cryptocurrency Exchange Application
A cryptocurrency exchange application I built on the Ethereum network with a native token. As a senior front-end developer, I translated the Figma design into a React and Next.js-based web application and integrated the Ethereum network with Web3.js.
Mental Health Screening Application
An AI-powered mental health screening application for healthcare providers. As a full-stack engineer and member of the Agile team, I developed a therapist-patient screening interface with React and Next.js using the Figma design and user stories I was given. I also developed microservices for ingesting recorded screening videos and producing screening result reports for therapists and patients.
Creative Ads Headline Generator
A state-of-the-art advertising headline generator driven by Generative AI.
I have designed and implemented a prototype copywriting tool utilizing TypeScript, React, and MUI (Material UI). This innovative tool can generate highly pertinent advertising headlines based on provided input and an array of customizable parameters.
