  • Wellframe

    Software Engineering @ Wellframe, delivering personalized care when patients need it.

    June 2014


    I met Wellframe during Summer@Highland, stayed in touch and then joined them after college. I have learned loads, both technically and culturally about how to find product market-fit and grow in a massive and heavily regulated industry such as healthcare.

    I was an early software engineer taking Wellframe as a proof of concept in pilots with local hospitals to full enterprise readiness with Fortune 100 clients. Wellframe is delivering targeted interventions to patients through a mobile app, by offering a intelligent platform that personalizes care with clinically proven models and workflows.

    I was reponsible for everything from the Ruby on Rails backend, to a React-based frontend as well as general engineering practices and operation concerns such as CI and deploys.

  • Credport

    Co-Founded my first company with Connor, my roommate from college. Rollercoaster would be an understatement.

    Boston, MA and Berlin, Germany
    Since 2012


    Credport is a trust platform for P2P marketplaces. It allows the portability of trust metrics such as reviews and social connections that are especially important for the Sharing Economy. Everything started with Connor's and mine passion for efficiency. We saw great potential in the model pioneered by Airbnb, but thought that the way we deal with trusting stangers online could be improved upon.

    Under the supervision of entrepreneurially-spirited Professor Byers at BU, I started to create the first prototype. Soon after, we were admitted to Summer@Highland, an incredibly great and generous program for young entrepreneurs. Towards the end of the summer, we decided that we couldn't simply return to BU, which is why we applied to Startupbootcamp Berlin, got in and moved in with my parents.

    You can read Credport's post-mortem at The Tale of Credport.

  • Apture

    Interned at the semantic-web, contextual search company Apture (acquired by Google in 2011). My first real job.

    San Francisco, CA
    Summer 2011


    I have met Tristan at the Thiel Fellow event earlier the year and was immediately Tristan's passion and product sense. I told myself I had to work for him, no matter the outcome of the Thiel Fellow decision, and so I did.

    The beginning of my internship was quite scary, as I had no accomodation planned and it was the first time I had to dive into someone else's extensive code base. All while using a language and framework I never used before (Python/Django). Over time however, I get to appreciate all the things that make Silicon Valley one of the greatest places to work and live.

    Apture's product was (unfortunately discontinued) one of the greatest products of all time in my opinion. When you were reading something on the Internet, but didn't know what X or Y meant, you could simply highlight the term and Apture would give you a little popup with relevant information such as the entity's Wikipedia article, a Google Map, Youtube Videos, etc. It helped me tremendously as a non-native English speaker as well as fuel my curiosity. Before (and after :( ) Apture, I open up way too many Wikipedia articles in new tabs.

    Apture Demo On YouTube

    Among other things, I have sped up their local queries trenemendously and improved upon the UX of the map. Since users would generally look up locations of things they didn't know, a simple static map would often not be the best option. Instead, depending on the entity, we'd show a auto-zooming map to give context.

  • Boston University

    Attended college in the great city of Boston while pursuing a B.A in Computer Science.

    Boston, MA
    Since 2010

    Boston University

    Admitted into the inaugural class of the Kilachand Honors College and awarded the full-tuition Trustee Scholarship. Pursued a B.A. in Computer Science.

    I still count Boston University as one of the best things that could have happened to me. I grew tremendously as a person by immersing myself into American culture and getting to know people from all walks of life. It was also Boston that introduced my to Startups and Technology on a more professional scale.

    Course Work

    My Education has been deliberately more breath- than depth-focused. In my first two years in the Honors College, I had the fortunate of immersing myself into various disciplines. Espeically after my leave of absence, I have continued to gain the most of my education by broadening my horizon and taking classes in psycholopgy, philosophy, economics, international relations and visual arts.

    While I'm certainly not the biggest fan of the very theory/acedemia-oriented CS curriculum at BU, I did had my fair share of interesting courses, Machine Learning being my favorite.

  • Heinrich-Hertz-Gymnasium

    Attended the science-oriented high school and graduated with the Abitur with a GPA of 1.3

    Berlin, Germany
    2003 - 2010


    Attended the selective science-oriented high school in Berlin, cumulating in the Abitur, the German high education entrance certificate with a GPA of 1.3 (1.0 being best)

    I have loved my high school that allowed my to explore my academic interests among high-achieving peers. I have been class and school president and placed at the top of local and regional science olympiads.

    Only thing to complain about my high school is the quite devasting gender ratio of 1:5.

  • Event Photography

    Getting semi-serious with my photography hobby

    Berlin, Germany and Boston, MA
    2009 - 2010

    Event Photography

    As for many people, photography has been a close hobby of mine, not only for documentary, but artistic purposes as well. While this has been mostly a private endavour, I have peeked into the professional aspects of photography as well.

    For me, it started with Nightlife photography at Virtualnights. While it is, in many ways, a great job for nightlife-loving 18-year-old in me, it also is a really crappy one because of the hours. On the positive side, I did not had to worry about not having enough willing subjects.

    I later tried to get a foot in the door with Fashion Photography, and while I can put the Berlin and Boston Fashion Week onto my portfolio, I had to stop my venturing into professional photography because of time constraints. From this time, I especially appreciated my first exposure to a world unknown to me while covering exclusive locations and crowds.

  • First short

    Our first try at a short with my new camera yielded us a lucky second price in a competitiion on Youtube

    Berlin, Germany

    Short Movie

    After I got my first dslr, I was pumped to try out the video function. Back then, it was the first time you could possibly pull some nice video footage with amazing depth of field with a budget. The German parliament had a contest on YouTube for some creative entries to motivate especially the young population to vote. We took the opportunity and wanted to point out how mechanic many of us live their lives. It's time to break free and make your own decisions! We ultimately placed second and won a behind-the-secnes trip to the German parliament.

  • Tech Blogger

    A quick writing stunt at tech-blog

    Berlin, Germany

    Tech Blogger

    After seeing a job opening at my then favorite gadget blog, I decided to apply and see how it's like. At first, tt was pretty cool knowing that thousands of people would read your posts every day. However, the work itself was pretty dull. It most involved reading other blogs or press releases and create one generic post after the other.

  • Nam's Remote

    First money-making side-project

    Berlin, Germany
    Spring 2009

    Nam's Remote

    After the "success" of Maps Offline, I quickly realized the fun and reward of just building things that happen to solve a problem. Since I was always fascinated by alternative Input/Output methods to back then Mouse/Keyboard, I wanted to take advantage of the great sensors and technology the iPhone provided.

    This was also my first real side-project which involved me learning all the goodies of "real" programming. It took me a week to just understand Apple's "Hello World program". Eventually however, I managed to create something usable.

    Nam's Remote was heavily inspired by the Wii console and started with the idea that you should be able to use your iPhone as a steering wheel for PC games, much like YC-backed Flypad 4 years later. Furthermore, it included templates to remotely control media players, act like a touchpad/keyboard and many more.

    Nam's Remote YouTube Demo

    In hindsight, just like Maps Offline, I'm quite amazed how I have improvised and things worked out. I had no clue of memory allocation (nor ARC back in the days) and I had my brother do the basic design (as well as speak English in the videos). To control the host, I used the Java Robot API by sending RPC-like messages such as "|mousedown|300|200|" over a UDP connection. It was a lot of google, copy-paste and trial and error until it worked. And I am proud of it.

    Not only was I among the first 10,000 apps in the AppStore, Nam's Remote was my largest commercial success so far. Seeing the revenue figures right after school was out was quite exciting.

  • Maps Offline

    My first public side project ever.

    Berlin, Germany
    Summer 2008

    Maps Offline

    I don't even know whether Maps Offline deserves the connotation of side-project as it never exceeded 300 lines of code. And those lines are probably the ugliest mankind has ever seen.

    All started with my desire for the iPhone. It came out earlier in the year and I just needed to have it. It was just too damn expensive. Next best thing: the iPod Touch. Problem: No Internet on the go in the wifi-wasteland that is Germany. Back then, my internal navigation system wasn't quite upto modern standards. So I wanted maps offline.

    Like all good product stories, I was looking for a solution, couldn't find one, so I decided to try to build me own. Which is easier said than done without prior programming knowledge. Or official API's in the pre AppStore-days. In the end, I managed to scramble something together and lo and behold, people actually liked what I was doing. Seeing five-digit download numbers for something like Maps Offline still baffles me.

    To date, I trace all of my major life events back to this moment. To get a glimpse at the great quality of Maps Offline, watch the following Video:

  • START Scholarship

    Support that I will be eternally grateful for

    Berlin, Germany
    2007 - 2010

    START Scholarship

    The START-Scholarship is a Germany-wide scholarship for motivated immigrant students with a financial need. It had a great impact on me and my view on a multicultural society. I was actually rejected the first time around.

    It was the first time I was exposed to different cultures apart from the German majority and Vietnamese subculture. Not until did the program support me financially, but also organized educational trips and seminars in various topics. It was especially the financial support that allowed me do live and learn more independently and broadly. Amonst other things, it helped to purchase the Macbook crucial for the development of Nam's Remote as well as my camera.
