Starting from long-term curiosity in programming and grounded in formal computer-science training, I keep refining system design, engineering abstraction, and delivery discipline.

Capability Source: 10+ Years in High-Standard Technical Roles
I entered service at 18 and spent over a decade in high-standard technical roles, building strong capability in complex-system decomposition, process standardization, and reliability-first execution.
03
Current Focus: AI, Generative AI, and Multi-Agent Product R&D
Since leaving service in 2020, I have transferred my computer-science foundation and engineering execution framework into AI product development, continuously shipping translation, XIKE, DuetCheck, and multi-agent panel products.

TRANSLATE
Yihang Live Translate
Turn foreign-language screens into interfaces you can actually use in Chinese.
Scenario
When reading overseas websites, emails, and software interfaces, you do not want to break flow by copying, pasting, and switching translators.
Usage
It recognizes on-screen text in real time and overlays translated text near the original location. It also supports shortcut-based screenshot translation.
Outcome
It only requests screen recording for local OCR, without microphone or system-audio access, ideal for long-form foreign interface reading on macOS.
An offline calm-audio player plus a fully free sleep dashboard: no network, no account, no subscription, no health-data upload.
Scenario
For calm music, body scan, pre-sleep breathing, or nature sound scenarios, Offline Calm ships with 226 tracks, 12 categories, and 125MB built-in content that works in airplane mode.
Usage
Sleep reads existing Apple Health sleep stages, heart rate, and HRV locally, then renders deep-sleep/REM ratios, seven-night trends, and an intelligent score for free.
Outcome
Offline Calm is a one-time lifetime purchase at ¥29.99, including Solfeggio frequencies, binaural beats, loving-kindness meditation, walking meditation, anxiety rescue, morning wakeup, sleep guidance, yoga background, and bilingual voice guidance.
An all-in-one iOS workbench for freelancers, connecting time tracking, project management, and invoicing in one flow.
Scenario
Freelancers need to manage clients, projects, hours, income, and invoices without jumping between timers, sheets, exchange-rate tools, and PDF utilities.
Usage
Start timing in Today, bind work to client and project, auto-calculate income by hourly rates, then generate multi-currency invoices and export to PDF in Invoices.
Outcome
It turns “Time → Project → Invoice” into a continuous pipeline and is built for commercialization with SwiftUI, SwiftData, private CloudKit, multilingual RTL support, Sentry crash tracking, and Pro IAP flows.
Good topics include live translation, generative AI applications, XIKE offline calm and sleep products, freelancer workbench tools, personal websites, software and game development, and multi-agent dashboards.
Good Fit
Small AI tools, mobile prototypes, desktop productivity tools, multi-agent panels, and showcase sites.
Not Ideal
No clear scenario, feature piling without priorities, or large teams requiring long-term onsite staffing.
