Ariya Hidayat’s Experience
-
Software Engineer
Nokia
(Public Company; NOK; Telecommunications industry)
2008 — Present (1 year)
Working for Oslo-based Qt Software Unit (formerly known as Trolltech ASA), on the development of Qt, the #1 graphical C++ application framework.
* Actively participate in the WebKit community (with commit and review status). WebKit is the most popular open-source web rendering engine used among others in Google Chrome, Apple Safari, Nokia S60 Browser, Apple iPhone, Google Android, Palm Pre, and many others.
* Improving, maintaining and bugfixing QtWebKit module, the Qt port of WebKit.
* Polishing and optimizing graphics and canvas in Qt, for modern desktop and in particular for mobile devices.
* Showing biweekly (mostly graphics related) tips, tricks, and example code at Qt Labs (http://labs.trolltech.com/blogs/author/ariya). -
Developers
Open-Source Projects
(Information Technology and Services industry)
2001 — Present (8 years)
In the past 8 years, I contribute several hundreds thousands lines of code to various open-source projects, among others:
* WebKit (http://www.webkit.org), mainly for the Qt port (QtWebKit).
* KDE, for its office suite KOffice (http://www.koffice.org). Some important improvements made to the are memory-efficient DOM/XML, more than a dozen file format conversion filters, performance and general optimizations.
* SpeedCrunch (http://www.speedrunch.org), an open source, cross-platform scientific calculator. It is the default desktop calculator for Kubuntu Linux, also available for Linux distributions (e.g. OpenSUSE, Debian, Fedora, Gentoo), Microsoft Windows, Mac OS X.
* libwpg (http://libwpg.sf.net), a library to read clip-arts in Corel WordPerfect Graphics (WPG) format. This library is used in other open-source software such as OpenOffice.org (Novell's edition), Abiword, and KOffice. Massive improvements to libwpg has been made during a Google Summer of Code project. -
Research Assistant
Universität Paderborn
(Research industry)
2003 — 2008 (5 years)
Realized the world fastest, record-breaking high-speed endless polarization controller with FPGA-based digital controller (for optical polarization multiplexing and PMD compensation).
Conducted research and experiments on the polarization aspects in the high-capacity 40-channel WDM optical transmission system employing DQPSK modulation and polarization multiplexing, reaching a world-record total C-band capacity of 6 Tb/s. Carried out a lot of development on optical components and systems, digital microelectronics, FPGA, instrument interfacing, etc.
Experiment results (more than 30 papers) have been presented in leading international conferences and peer-reviewed journals on photonics system, among others Optical Fiber Communication (OFC), European Conference on Optical Communication (ECOC), Asia-Pacific Optical Communications Conference (APOC), Journal of Optical Communication (JOC), Optical Fiber Technology (OFT), Electronics Letters (EL), and Photonics Technology Letters (PTL). -
Research Assistant
Control Laboratory, ITB
(Industrial Automation industry)
1999 — 2002 (3 years)
Developed few embedded systems, especially for automation applications. Designed complementary solutions (involving reverse engineering) for legacy products.
-
Technology Writer
InfoLINUX
(Publishing industry)
2002 — 2002 (less than a year)
Published over 70 articles in InfoLINUX magazine (the first and the only Linux and free software/open-source magazine in Indonesia), mostly on news coverage, general features, applications and games reviews, open-source evangelism, and GUI programming.
