During 4 years at Ho Chi Minh University of Science, I am the team leader of my ACM-ICPC team. My team is always the top performance team in the university. I and my team has been qualified for the ACM-ICPC World Finals for 2 times. Not only a contestant, I am also a coach for other teams, in 2016 I am invited to be a problem setter for the ACM-ICPC regional contest.

I am passionate about algorithm. When I was a high school student, I spend 2 hours each day for studing algorithm and practice with many online contest on Codeforces, Topcoder and many others sites.

At the National Olympiad of Informatics for high school student in 2012, I got the First Prize with the highest score among all the student.

In 2013, I also become the Champion of the Vietnam Olympiad of Informatics for collegiate student although the fact that I was a freshman in the contest. In 2014 and 2015, I also become the Runner Up for the contest. In 2016, I am invited to be the judge and tester for this contest.

Busmap is the my first professional product when I first learning mobile development. This application is a smart bus map to help people use bus system in Ho Chi Minh city more easily. Busmap achieves many prizes in mobile development as well as startup contests.

Currently, with the supported of Ho Chi Minh department of transportation, Busmap is built to become a system with many platforms. The application is not only helping more than 100k people using bus in Ho Chi Minh city but also a lot of foreigners. We also release an unoffical version of Busmap for Hanoi bus system. In the future, I hope that Busmap can be developed in many other contries outside Vietnam.

To develop Busmap I need to learn many knowledge, not only mobile development but also web development, backend development, server management... and many other things. I can say that Busmap has gained me to become a full stack developer and help me to have many precious experiece about running a real product by myself.

Last summer I passed the interview for an internship from Google. I traveled and worked in Googleplex, I joined the Identity team of Google and has learned many knowledge and great experience.

Working in a big company like Google has gained me in many aspects, not only techical aspects but non-techical aspects also.

I think that I have passed the interview from Google because of my good ability about algorithm, creative thinking, IT knowledge and experience.

I think my most important and the only skill I need is fast learning. I am willing to learn anything to help me achieve my target, with this skill I can easily adapt with diffrent projects, works and environments.

Working at Google is not my first internship but actually my third one.

Since I was a sophomore, I start having internship during the summer. I want to have as much work experience as possible, and working in different kinds of company gaves me different types of exprience. More over, I am also interested in research and during my second year, I have 2 papers about Computer Vision published at conferences: HCII and ICARCV.

Research Experience

• Paper: Applying Saliency-based Region of Interest Detection in Developing a Collaborative Active Learning System with Augmented Reality at HCI International 2014.
• Paper: Essential Keypoints to Enhance Visual Object Recognition with Saliency-based Metrics at ICARCV 2014 - The 13th International Conference on Control, Automation, Robotics and Vision.

After gaining experience abroad, I turned down opportunities to work at major foreign technology companies and chose to come back to Vietnam to build startups. I wanted the freedom to create my own products for Vietnamese people and to solve problems I truly cared about.

From 2017 to 2019, instead of jumping straight into my own company, I joined a different startup almost every year to learn how to build and run a real business — growing from a programmer to Tech Lead, Head of Engineering and CTO.

Looking back, choosing to come home and start up on my own homeland is a path I am proud to have chosen.

BusMap started as my student side-project back in 2013. After years of running it on my own, in September 2019 I finally turned it into a real company — making the leap from a passion project to a startup founder and CEO.

One year later, in 2020–2021, BusMap raised 1.5 million USD from Phenikaa Group (founded by businessman Ho Xuan Nang) and became Phenikaa MaaS, a smart mobility company building digital maps, AI and recommendation technology to solve urban transportation in Vietnam — and beyond.

During the COVID-19 pandemic, our team applied the same map technology to build CovidMaps, helping people and authorities track real-time pandemic information and identify high-risk areas.

In 2022 I achieved a rare double honor that very few people earn: being named in both Forbes Vietnam 30 Under 30 and Forbes 30 Under 30 Asia in the same year, for my work building BusMap and Phenikaa MaaS.

The recognition is not really about me — it is about proving that young Vietnamese engineers can build world-class technology products at home and use them to make everyday life better for millions of people.

Recognition summary

• Forbes Vietnam 30 Under 30 and Forbes 30 Under 30 Asia — a rare double title achieved in 2022 (Industry, Manufacturing & Energy).
• One of only a handful of Vietnamese honored at the Asia level that year.
• Over 100 national and international programming awards, including two-time ACM-ICPC World Finalist.
• Featured widely in domestic and international tech media — see the Press page.

My current focus is GoLabs, where I am Founder & CTO. We build smart-transport technology — including AFC (Automated Fare Collection) and ITS (Intelligent Transportation Systems) — that apply AI and big-data analysis to optimize public transport operations.

Our cashless payment solution for buses has been successfully deployed in Ho Chi Minh City and for VinBus, letting passengers pay quickly and contactlessly instead of using cash. It is my continued mission of using technology to make everyday life better for people in Vietnam.

For this work, in 2025 I was honored as one of the Top 5 AI Talents of Vietnam (AI Awards 2025).
