About Me

Software Developer from Jakarta, Indonesia.

Hello everyone, welcome to Freedomofkeima Zone! My name is Iskandar Setiadi. I've received my B.S. (2015) in Informatics from Institut Teknologi Bandung (ITB). I love to explore quite a broad range of computing technologies: mobile development, web technology, cloud infrastructure, and network security. I mainly take on back-end development projects. On the other hand, I am also able to cope with other development parts to a certain degree. It's fun to solve complex problems in elegant way!

Technical Skills

Mobile Development


By delivering excellent functionalities and self-explanatory user interfaces across different devices, it ensures all of my clients to have an enjoyable experience with my applications. I also provide a well-structured documentation which allows other developers to quickly adapt with my projects. These projects are developed in Java.

Web Technology

PHP  Node JS  Java  Python

I have developed several projects which are written in PHP (Code Igniter, Yii, Wordpress CMS), Node JS (Express JS + Angular JS), Java (Play), and Python (Flask).

HTML5 Family

As front-end development isn't my main ability, I can still deliver simplistic but intuitive interface designs to my projects. The good understanding of HTML5, CSS3, and Javascript ensures me to achieve this target.

Cloud Infrastructure

As cloud enthusiast, I've deployed several projects in Amazon Web Services. I also love to explore a broad range of distributed database systems (MongoDB, Riak, Cassandra, etc). My thesis is also focused on cloud infrastructure, which is titled as "Geographically-Aware Distributed NoSQL Prototype Development".

Network Security

I believe that network security has an important role in all software products development. I've learned several cryptography techniques (hash, signature, message encryption) which are quite handy in software development. I've also participated in a research at JAIST, Japan. This research is focused on elliptic curve cryptography algorithm and implementation over coordinate systems. The implementation itself is written in C++.

Other Skills

In many projects, I use several tools such as Git, package management (Bower, etc), open-source library (jQuery, etc), and graphics editor (Photoshop, etc).
