Speech recognition solutionsLanguages and dictors identification, diarization [2011-today]
I have a lot of r&d projects at STEL Computer Systems. GMMs, Supervectors, Neural networks (Kaldi and others), etc are widely used in my daily practice. I visit international conferences in this area and have publications there. All researches are run under Python and C++. Also we develop a speech processing SDK and make high performance computing solutions with CUDA.
Testarium: Research tool, open sourceResearch tool to perform experiments and store results
as in the repository [2014-today]
It implements scientific template of experiments and uses numpy, colorama, flask, d3, jquery-ui and angular to provide powerful shell and beautiful presentation of your experimental data and scores.
It can be helpful for science researchers and their managers to monitor the work progress and to optimize parameters. I use it in my work with neural networks, speech recognition tasks and others. Go to testarium.makseq.com.
Wormtune: Music by timbral searchOnline service for music search by timbre [2012-2013]
Together with my colleagues I have developed a sound search platform (Samplefinder). It provided building a timbral index over million song dataset. Based on it we started online audio service: wormtune.com.
ECG Demodulator and iOS/Android Mobile AppFM Demodulator for the electrocardiogram signals (ECG) [2013-2014]
iOS/Android mobile app for ECG recording and management [2014-2015]
Later I designed and developed with my team iOS / Android application for KardioDom based on this demodulator.

Loopseque/MovBeats. Audio/Video sequencers for iOSLoopseque - audio sequencer for iOS [2010-2012]
MovBeats - video sequencer for iOS [2011-2012]
Maths and programming of audio processing, sound engine architecture, concept & ideas generation, audio routing scheme, some of UI programming, asm maths optimizations for ARMv6 processors - all of them were mine.
MovBeats is using my audio engine from Loopseque with little changes in audio routing scheme.

Adaptive noise reduction system based on multi-resolution FFTOnline audio denoising service [2007-2009]
My master graduate work became an online service further. But now I have stopped support and closed the service.
