About
I work at the intersection of product thinking and engineering execution.
What matters most to me is not just understanding a technology, but turning it into a usable system or a real product. That usually means moving from research and experimentation to implementation, iteration, and delivery.
My work spans independent iOS app development, AI-assisted workflows, data analysis, embedded devices, robotics-related experimentation, and applied system design. I tend to approach problems by breaking them into smaller parts, validating assumptions quickly, and pushing toward something that is actually usable.
I am currently interested in full-time opportunities in AI product, technical solutions, and intelligent hardware.
Core Work
ShiguangJi: Building an iOS Product from Zero to One
- Role: independent developer
- Scope: research, product design, frontend and backend implementation, testing, launch preparation
- Stack: Swift / SwiftUI, Supabase, AI food recognition APIs, UI/UX design
Master’s Research: Fatigue Recognition in Robot-Assisted Squat Training
- Role: master’s research designer
- Context: investigated how to recognize fatigue during robot-assisted squat training
- Focus: combined subjective fatigue ratings (RPE), surface EMG signals, and platform-recorded kinematic data to compare how different indicators reflect fatigue
- Why it matters: the work connects to rehabilitation training, intelligent exercise systems, and safer human-robot interaction, while also reflecting hands-on experience in experiment design, data collection, signal analysis, and research writing
