The hands: turn the plan into a system that runs.
Shanghai DeltaEcho Network Technology · Est. 2026 · Zhangjiang
We put AIto real use
DeltaEcho was founded in 2026 in Zhangjiang, Shanghai. We go on site, find the steps where AI actually pays off, build the system, and sign it off against numbers agreed up front.
OPC · One-Person Company
A company of one. A delivery team of many.
DeltaEcho is an OPC, a one-person company. AI agents take on the legwork in parallel, I make every call that matters, and when a project needs deep industry knowledge, a domain expert joins in.
- Three months max
- A prototype in week one
- Only measurable promises
AI drafts the code; I set the architecture and review every change
AI digs through sources; I keep what holds up
AI runs the tests; I decide what counts as a pass
AI sketches; I walk you through it
AI drafts; I check every line
AI watches the numbers; I judge anything unusual
First, one term: FDE
Engineers who go where the work is
FDE stands for Forward Deployed Engineer. Instead of building software from a distance, an FDE works on site, wires AI into the real workflow, and stays until people use it every day.

AI won't wire itself in

Hello
I'm Wang Shiyi
I do both jobs myself. Six years in financial data, from product ops to AI solutions architect; in the last two years I've helped 17 companies make AI part of their daily work. Now I teach it, too.

Selected work
Two years, 17 companies. Only what got done.
Manufacturing, financial information, professional services, content operations, edtech and a state-owned energy group. Client names stay confidential under NDA.
Seventeen client names stay under NDA. Three of them have anonymized case studies.
Media monitoring agent · A management consulting firm
Five people's work, done by one in a tenth of the time
Five people used to spend half of every day collecting, filtering and writing the daily brief. After delivery, one person does it in a tenth of a working day. Contract to sign-off took one month.
Bid evaluation assistant · A state-owned energy group
Every finding cites its source, and experts still do the scoring
It runs in an offline, classified environment. Every conclusion links back to the original text so reviewers can check it. AI only organizes and finds evidence; the scoring always stays with the experts.
Production knowledge base · An equipment manufacturer
Veteran know-how, searchable any time
Process specs and the experience veteran technicians carried in their heads now live in a knowledge base that new hires can search any time. After phase one passed acceptance, the client signed on for phase two.

How I work
01Listen first
On site, I dig through the books and the systems. The problem people describe is often not the one that costs money.
02A prototype in week one
Something you can click and try in week one, refined as you use it. No months-long build before you see anything.
03Measured in numbers
Before launch we agree on what success means: hours saved, errors cut. It's delivered only when it hits the mark.
04Your team takes over
Once the system is in your team's hands, I keep coaching until it runs smoothly without me.
Echo Camp
Three days to turn industry experience into AI deployment skills
Opens early NovemberIn person, Shanghai30 seats in cohort one
No lectures. For three days you work as a Forward Deployed Engineer in a lifelike simulated company: uncover the boss's real need, find the evidence, build a demo, then sell it to the boss.
How the three days run
Day 1
Level 1ClearedListen & ask: get past the boss
Get the truth out
Learn to interview, watch a mentor run a full client interview live, then drill in pairs, taking turns as consultant and boss. At night you enter the main storyline, The Great Cancellation: a gym chain where everyone has an agenda.
Day 2
Level 2ClearedRead & translate: get past the evidence
Match what's said to what's true
Use AI to read the company's business systems and check last night's claims against the data; where they don't match is the real need. Then build a clickable demo in three hours and sell it to the “boss” that evening.
Day 3
Level 3ClearedProve & pitch: get past the close
Stand up to the judges
Draw a brief from an unfamiliar industry and run the whole process solo in three hours. Then give an 8-minute pitch and take rapid-fire questions from the judges, scored against a rubric published on the spot.
Core training tools
A “living company” you can dig into
At its core is an FDE role-play: six characters with their own tempers and stakes who only open up to the right questions, and business systems hiding numbers that don't add up.
Six things you'll take home
- 01A Needs Card backed by a chain of evidence
- 02A one-page proposal and a one-page results brief
- 03A clickable demo you can show anyone
- 04Your 8-minute pitch video, Q&A included
- 05A portfolio outline and three versions of your career story
- 06A certificate and digital card with a lifetime serial number
For product, operations, data, marketing, finance BP, consulting, solutions and pre-sales people with three or more years of experience. No coding needed; if you have used an AI chat tool, you are ready.
Enterprise AI Rollout Role-Play · In-Person Session
FDE Role-Play
Two and a half hours to work out whose need is real
CASE FILECONFIDENTIAL
A consumer brand decides to adopt AI. Someone wants to make it happen, someone has to deliver it, someone stands to gain, and someone feels their seat is under threat. The outside consultant has two and a half hours to work out whose need is real. Every role has its own mission and clues, and nobody watches from the sidelines.
TABLE · EIGHT SEATS
Five role types, eight seats per session, assigned before play. Two players with the same role are not necessarily on the same side.
Shared storyline
Together, the table takes one company's AI rollout from green light to real use
- Green lightThe boss says yes to AI. The budget is signed; the full story isn't told.
- InterviewsTalk to everyone. Each has something to say, and something they'd rather not.
- EvidenceHold every claim up to the facts. Where they don't match, there's a clue.
- AlignmentEvery agenda goes on the table. Who gives ground, and who won't budge?
- Trade-offsWhat goes first, what gets cut, and who puts their name to it.
- Real useIt only counts if people actually use what gets built.
- DebriefBefore everyone leaves, the host gives each player a short read on how they did.
Hidden agendas
Five role types, each with something to hide
Every role has private goals and worries. Some back the plan, some wait and see, and some quietly work against it. Your clues are for your eyes only.

Full refund or a session change up to 24 hours before start. The role-play uses the same method as Echo Camp, so if you want the full training, the camp is the natural next step.
Open source
I build tools, and share them
Tools I write along the way on client work, cleaned up and open-sourced for anyone to use. The most popular one is a verifiable mirror that lets people in mainland China download the Codex desktop app directly.

FAQ
Questions you might have
What is an FDE?
FDE stands for Forward Deployed Engineer. Instead of building software from a distance, an FDE works on site, wires AI into the real workflow, and stays until people use it every day.
How can a one-person company deliver?
DeltaEcho is an OPC, a one-person company. AI agents take on the legwork in parallel, I make every call that matters, and a domain expert joins when a project needs deep industry knowledge. Three rules keep it honest: three months max per project, a prototype in week one, and only promises that can be measured.
Where should a company start with AI?
Start with an assessment. We look at your operation on site and tell you where AI is worth it, what it will cost and how soon it pays back. Email [email protected] with your company, your industry and the problem you want to solve.
Do I need to code to join the camp?
No. Three or more years of work, real industry experience and some time with an AI chat tool are enough. This cohort does not take complete beginners or pure software engineers.
Where and when is the camp?
Cohort one opens in early November for three days, in person in Shanghai. Exact dates and venue are sent after you sign up. The sign-up pages and camp materials are in Chinese; email us with any questions.
Can I get a refund?
Cancel more than 3 days before the camp starts for a full refund. Within 3 days of the start, we refund half of what you paid or move you to the next cohort for free. No refunds once the camp begins. If we cancel or postpone, you get a full refund.
Do you guarantee a job or clients afterward?
No. What we offer is skills, a portfolio and a path in: graduates join our talent pool and get priority when real demand comes up, but we don't guarantee it or put a timeline on it.
