Good morning everyone. My name is [YOUR NAME] and I'm from Fabbi.
Today I want to share some of our projects. But first — why do these projects matter?
[pause]
Fabbi is a Vietnamese company with offices in Japan and Australia. Over 100 people. More than 10 years of experience.
We build software. But we don't just build software — we build solutions that help businesses grow and help society improve.
[pause]
For business — we help our clients save money, work faster, and reach more customers. Some of our clients saved up to 67 percent in cost. We work with companies in Japan, Hong Kong, Vietnam — so we understand different markets.
[pause — gesture to society]
But what we're really proud of is the social impact.
We help make the planet greener — with DCarbon for carbon credits and EVCharge for electric vehicles.
We help make education better — with Minh Tri Thanh for parents and children, ThanhMaiHSK for Chinese learners, and HWorksheets — free digital tools for Vietnamese schools.
We believe good technology should reach everyone — not just big companies or rich families.
[pause — closing]
So today, let me walk you through these projects. You will see how each one creates real value — for business and for people.
Hello everyone. Today I want to introduce DCarbon project.
DCarbon is a platform for carbon credit. It helps companies and people to buy and sell carbon credit online — easy and safe.
[pause]
What is the problem? Right now, carbon offset process is very difficult. Many small projects cannot join the market. The market is not connected. And people don't trust the data.
What DCarbon does? DCarbon uses blockchain and IoT devices to solve this. Blockchain makes the data transparent — everyone can check. IoT devices collect real data from the field — so no one can fake the numbers.
[pause — point to slide]
Three main points:
First — Trustworthy. All data is on blockchain. You can verify everything. No cheating.
Second — Support small projects. Small farms, small forests can also join and sell carbon credit. Auditing can be done remotely.
Third — Secure. We use encryption to keep all data safe.
[pause — point to numbers]
Some numbers: 30 thousand projects, 26 thousand organizations, and 1.69 million users on the platform.
We built this with Rust, Solana blockchain, Next.js for the website, NestJS for backend, and Arweave for permanent data storage. Team of 8 developers over 16 months.
Thank you. Any questions?
Now I want to talk about our EV Charging project.
We built a complete system to manage electric vehicle charging stations. The client is Cornerstone Technologies in Hong Kong.
[pause]
Why EV charging matters for the environment? Electric vehicles produce zero emissions — no CO2, no smoke. But to use EV, we need charging stations everywhere. Our system makes it easy to build, manage, and use these stations. More charging stations means more people switch from gasoline cars to electric cars. That directly reduces air pollution and greenhouse gas.
Also, our system has smart energy management. It balances the electricity load — so charging stations don't waste energy.
[pause — point to diagram]
The system has three parts:
First — CPO, for the operator. They can manage all stations, check status, and assign staff through a web portal.
Second — eMSP, for the driver. Users open the mobile app, find a station, charge the car, and pay. Very simple.
Third — EMS, energy management. The system automatically balances electricity so the grid stays stable.
[pause — point to numbers]
The system connects to charging stations using OCPP — an international standard. So it can work in any country, not just Hong Kong.
Some numbers: 75 stations, 920 charging points, over 28,500 sessions, and 1.1 million US dollars in revenue.
To summarize the environmental impact: every charging session means less gasoline burned, smart energy means less waste, and cross-border means more countries can go green faster.
Team of 20 plus developers, built in 1 year. Thank you!
Let me introduce the Minh Tri Thanh project.
Minh Tri Thanh is an online education platform in Vietnam. It focuses on therapy education — helping parents and teachers learn how to support children's mental health and development.
[pause]
What we built? We built a complete digital education ecosystem — not just one app, but many products working together:
An LMS where teachers create courses and students join virtual classrooms. It can handle tens of thousands of users every month.
A website and e-learning app — students watch live sessions, take courses, and get certificates online.
An audiobook app — people can listen to education content anytime, anywhere.
A running tracker app to encourage physical activity in the community.
And an admin system for the company to manage all learners, payments, and content.
[pause — transition to AI]
How does AI help this platform?
AI recommends the right courses for each learner — based on their needs and progress. AI helps teachers analyze student performance — who is struggling, who needs more support. And the virtual classroom uses smart tools to make online learning feel more interactive and personal.
[pause — community]
Community impact is very strong. Tens of thousands of parents join live sessions every month — like the "Cha Me Tinh Thuc K12" program. It connects experts with families across all of Vietnam — not just big cities, but also rural areas. The platform builds a community where parents share experiences and support each other.
Why it matters? In Vietnam, access to therapy education is limited. Most experts are in Hanoi or Ho Chi Minh City. This platform breaks that barrier. Any parent, any teacher, anywhere in Vietnam can learn from top experts — just with a phone and internet.
Team of 12 developers, completed in just 5 months. Thank you!
Next project is ThanhMaiHSK — an online Chinese learning platform.
ThanhMaiHSK is a well-known Chinese language school in Vietnam, founded in 2012. They needed a complete digital platform so students can learn Chinese online — anytime, anywhere.
[pause]
What we built? A full ecosystem for learning Chinese:
An e-learning system — students watch video lessons, join live classes, and practice with quizzes. The system tracks attendance and grades automatically.
An LMS for teachers to manage their classes and see how students are doing.
A mobile app — students can learn on their phone. Very convenient — practice Chinese on the bus, during lunch break.
An online library with Chinese books, dictionary, and study materials — all in one place.
And HSK mock exams — students can practice the real test format before the actual exam.
[pause — AI section]
How AI helps? The system creates personalized learning paths — AI analyzes each student's weak points and recommends the right lessons. There are over 3,500 smart exercises with intelligent feedback. And attendance and grading is all automatic — teachers save time, students get instant results.
[pause — closing]
Why it matters? Chinese is becoming very important for business in Vietnam. Many companies need staff who speak Chinese. This platform helps thousands of Vietnamese people learn Chinese faster and cheaper than traditional classrooms.
Team of 12 developers. The system is completed and operational. Thank you!
The last project I want to share is very special — it's called HWorksheets.
HWorksheets is an interactive digital learning platform for schools. But what makes it different is — this is our CSR project. CSR means Corporate Social Responsibility. This is Fabbi giving back to the community.
[pause]
What is the problem? In many Vietnamese schools, teachers still use paper worksheets. They spend hours creating exercises, printing them, and grading by hand. Students don't get instant feedback — they have to wait days to know their results.
[pause — point to classroom photo]
What we built? A platform where teachers can create interactive digital worksheets. Students do exercises on the screen or on the classroom smart board. The system grades automatically — students get feedback right away.
Teachers can track which students are doing well and which ones need extra help. Everything is digital — no more paper, no more waiting.
[pause — CSR message]
Why this matters? As a technology company, we believe technology should help every child learn better — not just children in expensive private schools. HWorksheets is our way of making that happen.
It bridges the digital gap in Vietnamese education. It reduces paper waste — so it's also good for the environment. And most importantly, it makes learning more fun and engaging for kids.
This is what we're proud of at Fabbi — using our skills to make a real difference. Thank you!
