How It Works

02 / PROCESS
STEP 01
Scope Call (Free)
30-min async or live call. You describe the problem, I confirm whether it's solvable and give a rough estimate on the spot.
STEP 02
Proposal + Fixed Quote
Within 24h I send a written spec with fixed USD price, timeline, and deliverables. No hourly billing surprises.
STEP 03
Build & Review
Weekly async updates with live demos. You review and give feedback. I revise until it's right — revisions are included.
STEP 04
Handover + 30-Day Support
Full code, docs, and deployment walkthrough. 30 days of free bug fixes and questions after delivery. No ghost.

Why Work With Me

04 / WHY
⚡
AI-Accelerated Delivery
I use Claude Code, Cursor, and AI-assisted pipelines in my own workflow. That means the same scope ships 2–3× faster than a traditional freelancer — at the same price point.
$
Fixed Pricing, No Surprises
Every project gets a written proposal with a fixed USD quote. No hourly rates that balloon, no scope creep billed silently. Changes go through a clear approval step.
🌐
Async-First, Global TZ
Based in Nanjing, China (UTC+8). I've structured my workflow for async collaboration — daily update posts, Loom walkthroughs, and responses within 12h. Works well for US/EU clients.
📄
Full Handover, Always
Clean code, architecture docs, deployment instructions, and a recorded walkthrough — every time. You own everything and can run it without me. That's non-negotiable.
