Experience
Monash Vacation Research Scholarship Program
I am responsible for the design and development of an AI-driven generative system for 3D-printed footwear. The core modules include high-precision foot scanning utilizing iPhone LiDAR and binocular cameras, an AI engine for parameter-driven shoe last generation based on foot morphology, an automated CAD workflow for upper and sole optimization, and an integrated algorithm for the automatic generation of lattice structures from CAD models. I plan to submit a research paper on this work in the first half of next year.
Full-stack Software Developer
Founded a personal software company, Oiy AI, and independently delivered multiple enterprise-level AI Agent projects, such as the voice custom services agent Ringbot, the open source learning agent Learnify, and a customized fire safety report drafting agent, among others.
Senior Software Engineer
Led a technical team of 22 people at the Nanjing R&D Center, reporting directly to the CTO. Directed the restructuring of the team into project-based units, adopted agile methodologies, and introduced AI-assisted programming to all teams, resulting in a 60% increase in development efficiency. Implemented stand-up meetings, code reviews, automated DevOps workflows and containerized deployment, achieving an 85% reduction in customer-reported issues.
Software Engineer
I contributed to the development of a B/S architecture PLM system, where I played a key role in the development of many core functions.
Software Developer
Developed many Siemens Teamcenter projects with more than 100 complex functional modules. Developed several B/S projects.
Project
Learnify Alpha Version: https://learnify.oiy.ai
An AI-powered learning tool that can help users learn everything faster and better.
User can upload files in different formats (PDF, Word, Excel, PPT, Images, Youtube Links, etc) and Learnify will generate syllabus, mind maps, summary notes, flashcards, quizzes, podcasts and more.
What's even better is user can get 1v1 teaching experience by rasing inline AI chats in Notes, asking for detailed explanation in Quizzes, joining podcast as a guest then starting a real-time chat with the host.
My Contribution
It's an open-source project (https://github.com/oiy-ai/learnify). I founded it by myself and contributed everything. Besides feature development, I also:
- designed the technical architecture
- conducted research on the technical selection of every modules
- built the github actions pipeline for all services
- deployed the services to GCP, Cloudflare and a bunch of other cloud native services.
