Neural Networks Library

Neural networks library

April 2016 – Present | Singapore

Clojure-based neural networks library that is built on top of core.matrix package. I decided to create this library after completing Andrew Ng's Machine Learning course. The library is very modular where you can easily swap optimizer, activation/sigmoid functions, stopping conditions and cost function.

wearther is a web application (Node.js, Backbone, Titanium SDK for the native app version) that helps you decide what to wear based on the current weather. wearther's optimizer - MACHO (Multiobjective Ant Colony Heuristic-based Optimisation) is derived from an artificial intelligence algorithm (Ant Colony Optimisation) to calculate the best clothing combinations quickly so you can leave home feeling just right. Not too cold, and not too warm.

Software Developer


July 2015 – Present | Singapore

I joined Eyeota as a full stack engineer to work with Ember.js on the frontend for our internal webapp. Then I worked on the backend side to do a complete rewrite of our backend system using Clojure, ElasticSearch, and Cassandra stack.

The new backend offers much more flexibility, high performant and includes a complex access control rules. Our team is also in charge of the operational side of the system, so I learned about deployment using Ansible, metrics collection (what to collect and how to read them) with Graphite and Grafana, performed various operational tasks.

Software Engineer

Krux Digital

September 2014 – May 2015 | Sydney

Day to day, I worked with Python, Django, Tastypie, AngularJS, CoffeeScript, Sass, Node, Java, Chrome Remote Debugging Interface, a bit of Puppet and some AWS stuff (SQS, S3, EMR, Redshift, RDS)

I'm also involved with the upgrade of one of our core service that uses Java, Python, Google Chrome/Chrome Debugging Interface, and AWS stack (SQS, RDS, Redshift and S3). Google Chrome is used to create HAR files and and then we inject custom JavaScript tag to add additional informations. The processed file is then further processed by Java/Python service using AWS stack. The result is then stored in RDS, Redshift and S3.

Local Measure

February 2014 – September 2014 | Sydney

I joined to develop their new product using Go and MongoDB that monitors various social media posts for user-defined conditions (e.g. specific keywords, a minimum number of followers, location, etc). If there are any posts that match the defined conditions, we will aggregate the posts and send an email notification at a specified time and frequency. This is achieved by using multiple channels in Go. For this project, I was completely in charge in terms of the frontend development, I used Angular.js with heavy use of directives to avoid code repetition. I also created the Google Chrome Extension for this product.
