Hello everyone, I’m PoYu Chao (趙博宇), and I am currently seeking opportunities as a Full Stack Developer or Frontend Developer. I graduated from Northern Arizona University with a background in Software Engineering, and I bring with me one full-time development experience and two internship experiences.

Since Sep 2024, I’ve been working as a Full Stack Developer on a startup project called ArtBridge – an artist commission platform. Collaborating with a four-person team, I helped build the entire system from scratch. Key features I implemented include multi-step registration, real-time chat with milestone tracking, NewebPay payment integration, and backend API routes. I also developed responsive UI components such as user settings, a message board, and modals for image preview/upload. To handle growth, I optimized Firestore structure, improved Firebase listener logic, and applied centralized caching using Redux. I also used Next.js Middleware for session-based route protection

I previously interned as a Software Engineer Intern at Wonder AI, where I improved UI/UX and developed internal tools to support ##AI## model optimization using technologies like React.js, Next.js, Tailwind CSS, and Amazon S3. Before that, I worked as a Quality Assurance Intern at Phase Software (Taipei Office), where I wrote unit tests using Jest, documented bugs, and later contributed remotely to resolving React.js UI issues through Jira collaboration.

Wander-Internal-Tool

This full-stack project utilizes Next.js, React, and TypeScript for the frontend and interacts with AwsS3 for data storage. It implements RESTful-APIs to retrieve CSV data from S3, store user responses, and allow users to download their results from S3. The core functionality includes testing user preferences for responses from different AI models (ChatGPT, ChatGPT-4, Gemini) to ensure alignment with human feedback. The goal is to optimize machine learning models for better self-learning efficiency based on user feedback.
