Gonghui L.

Your Shopify checkout fails on mobile. A migration went sideways. An AI-built site works on localhost and dies in production. Lighthouse looks fine in staging and tanks after go-live. Those are the jobs I take. HOW I WORK: FULLY ASYNC, IN WRITING No calls, no scheduling across timezones. You get a written diagnosis before I touch anything, annotated screenshots, screen recordings with captions, and a written change log when the work is done. Most clients tell me this beats a 30-minute meeting: everything is documented and searchable instead of said once and forgotten. If you do prefer to talk, I take video calls in Chinese (Mandarin). I'm Gonghui Liu, based in Shanghai. Top Rated, 100% Job Success. About 10 years shipping web products: Senior Full-stack Engineer at YOUXIANG Technology Ltd. (2020-present) and Java/Spring Boot at GuangYi Tech (2017-2020). LANGUAGES - Chinese (Mandarin): native. Written and spoken, video calls welcome. - English: fluent in writing. All work, updates and handoffs in text. - Japanese: business-level reading and writing. Text only. If your team, suppliers or vendors are in China, that is where I am hardest to replace. I can read the Chinese-language docs, dashboards and vendor threads your other developers cannot. My largest contract here was exactly that: a 185-hour bilingual website migration for a Chinese-speaking client, finished at 5 stars. WHAT I ACTUALLY FINISH - Production rescue: WordPress / Shopify / WooCommerce / Elementor bugs, theme and custom PHP that will not survive the next deploy, checkout and form failures under real traffic - Speed that sticks: Core Web Vitals, LCP/CLS, technical SEO, with before/after numbers instead of "we installed a cache plugin" - Migrations and rebuilds: move or rebuild without losing rankings, forms or payments - Finish AI-built sites: OpenAI API chat, AI import and workflows, agent-style apps. Stabilize, secure and ship so real users can use them, not demo-only - Cross-border and bilingual builds: CN / EN / JP sites, localization that does not break layout or SEO PROOF - Bilingual real-estate site: Lighthouse Performance 99, SEO 100, about 1.4s mobile LCP, 0 CLS, AI chat plus AI-assisted import - UPSHIFT bilingual learning and collaboration platform - BrightNest Cleaning (WordPress business site) - Internal Business Dashboard MVP (Base44), Shopify theme customization - AI-Powered Short Drama system, AgentRoute Studio - GitHub linked on this profile, active since 2016 HOW I KEEP IT SAFE Staging first. Backups before risky changes. Version control. Written change notes on every step. I fix the root cause instead of stacking plugins on top of it. Day-to-day stack: WordPress, PHP, Shopify, WooCommerce, Elementor, Next.js, React, TypeScript, Node.js, Java/Spring Boot, OpenAI API. TO START Send the live or staging URL plus one or two sentences on what is broken or unfinished. You get back a written plan, a fixed price or an hour estimate, and an honest answer on whether I am the right fit, or who would be. Usually within 4 hours.
