Code for Good Glasgow

24-hour hackathon at JP Morgan Glasgow (November 2015)

Code for Good London

It's 24-hour hackathon held by JP Morgan. There were 20 teams with 4-6 students in each team, 4 non-profit organisations presenting their challenges. Each organisation was assigned 5 teams to work with. I was part of a team of 6 students (5 University of Edinburgh students + 1 St. Andrews University student).


My team was assigned to work on British Heart Foundation challenge. In general, the challenge was about how to improve customer experience and how to encourage people to donate more. We came up with an end-to-end solution that enables the stakeholders (donors, volunteers, BHF's employees) in doing their part. Demo video can be seen here: BHF Donate.
My role was to build the app solely. Source code can be seen here: Code for Good - British Heart Foundation - Team 2


we won the first prize (2 years in a row for me) :D


These are some mentions on Twitter:

Maglev Train Dashboard

I was asked to build an interactive dashboard with some data display (both generative and real) for underwater train. It's built with Processing 3. There are some features on the dashboard:

Skyscanner Roundtrip

The project was built during HackUPC, a 36-hour hackathon held by Universitat Politecnica de Catalunya, Barcelona. I was part a team of 3 people and there were some challenges given by Sponsors. We chose to use Skyscanner API to build an app that can be used to plan a multi-day trip on several cities under certain budget and finds the cheapest flight combinations. My role was a sole Android developer in the team.


We won the first prize of the challenge.

Find the code on github.

Sentiment Watch

DI Project is an individual project under given contexts. I chose a context called "Data as Art". I tried to answer the question "can we see information that we need just by glancing?". Watch was chosen as a medium to answer that. It's used to visualise data on its strap. The data are location (based on GPS drawing) and public opinion of particular location by analysing sentiment on Twitter data.


Puppet Stage AR

It was a project of Design with Data course. The project's context is National Scottish Gallery. We're asked to use available data owned by gallery such as visitors, paintings, etc. We chose to play with paintings and the story behind. We came up with a solution which is an Augmented Reality app with puppet stage as its companion. I was part of a group of 5 students and my role was sole developer. I built the app using Unity.


Open Doors

Edinburgh Challenge is a yearly challenge held by Edinburgh City Council. We joined the 2016's event. I was on the same team as my "Design with Data" team. We tried to give a solution to address loneliness issue especially for elderly. My role was doing market research and determined what kind of technology that we could leverage. We came up with a crowdsourced idea where people can contribute their time, probably 15-30 minutes a day to help such as to buy milk, or just accompany 1 elderly to have smalltalk. Then, we built a mockup prototype of a system that can be used to support that idea.


Code for Good

It's 24-hour hackathon held by JP Morgan. There were 12 teams with 5 students in each team, 3 non-profit organisations presenting their challenges. Each organisation was assigned 4 teams to work with. I was part of a team of 5 University of Edinburgh students. We just met on the hackathon day.

My team was assigned to work on Urban Roots challenge. We built a website and mobile app with the same set of features and additional feature to send vandalism report by taking picture, location, and description. I was a sole Android developer in the team.


We won the first prize :D
