Work Experience
Machine Learning Engineer
DataRoot Labs
- Designed a real-time AI system for tracking (from video) how the person is doing physical exercises, counting repetitions, and giving feedback on the technique.
- Designed a data pipeline for collecting app data (events, information, clicks) to perform recommendations.
- Built an "almost real-time" recommender ML model for rapidly changing items.
R&D Systems Engineer
Infineon
- Developed and validated a new generation touchscreen chip (ASM, C, C++, and C#).
- Implemented a program on C# for regressive testing support on PSVP.
- Validated and integrated a MUX board into the PSVP system from scratch.
- Contributed to developing the ML departure and built up expertise in this field.
- Replaced a classical empirical algorithm with neural networks (Python, C, and PyTorch).
Engineer
Skycoin
- Implemented support for a ledger device (all firmware with GUI, functionality, and user manuals) for Skycoin cryptocurrency.
- Proposed cross-device testing for the ledger support.
- Managed the technical part of the team that developed a personal security device to successfully release the product.
- Worked in cryptography and security development (generating, storing, and using private keys without explicit access to them) in low C.
- Maintained the community.
External Consultant
ELEKS
- Released a massive yet private scientific report on current quantum computing technology for the leading global consulting company.
- Researched multitudes of papers and learned from scratch basic quantum mechanic theory.
- Managed a team of two students, concisely producing valuable work and conclusions on current progress in QC, including opportunities and weaknesses.
- Researched quantum encryption and communication methods related to QKD (quantum key distribution).
- Wrote several quantum programs on QuTiP and IBM Q to test our ideas.
Blockchain Software Engineer
Merit
- Designed, planned, and implemented solo mining support for Merit cryptocurrency by enhancing communication protocol between workers and central pool (C++).
- Added GPU support for the Merit crypto mining library by using CUDA technology and C++.
- Integrated a C++ mining library into an Angular Electron application.
- Initiated and implemented mining data visualization and real-time charts for displaying mining information and controlling the state of CPUs and GPUs (load, temperature, and fan states). Used C++, Angular, and Electron.
- Worked on the currency core protocol, similar to bitcoin, to expand the referral system with messages and extend the transaction capability.
Project History
Neural Network for Image Captioning
https://github.com/Retsediv/ImageCaptioningMusic Transcription Using Q-Transform and Deep Neural Networks
So, if you have only recordings (MP3 files or so) of some melody you love but can't determine the notes, you can use this network to convert the raw melody into a sheet of notes.
