Design, development and implementation of commercial and scientific-applied software (more than 200 projects) for regular and new customers from idea to full integration. It does not matter if I have been working alone or with a team since the start of the project, I always participate personally in all stages of project development and implementation. One of the main features is the ability to close several positions at once at a high level, starting from communicating with the customer as a business analyst, architect and project manager, continuing with employee training and participation in software development, and ending with implementation, integration and presentation.I work with the following programming languages and technologies:- C / C++ (since 2001);- C# (since 2002);- CUDA (since 2007);- Python (since 2017);- Go (since 2020);- Rust (since 2020);- Db SQL (since 2002);- Db NoSQL (since 2017);- .Net (since 2001);- .Net Core (since 2017);- Backend (since 2017);- Desktop app (since 2002);- Mobile app: Android, iOS (since 2017);- WPF (since 2006);- Xamarin (since 2017);- MAUI (since 2022);- Data Science (since 2000);- Image/Video/Audio Processing (since 2000);- Computer Vision (since 2002);- Gen AI (since 2017);- NLP (since 2017);- Machine Learning (since 2013);- Deep Learning (since 2017);- FFmpeg (since 2001);- OpenCV (since 2006);- Pytorch (since 2017);- Tensorflow (since 2017);- Algotrading, Crypto, Web3, DeFi, NFT, Blockchain (since 2020).Scientific area: Computer Vision, Image/Video/Audio Processing, Gen AI, NLP, ML, DL, OpenCV, FFmpeg, libav, PyTorch(LibTorch), Tensorflow - CNN, Autoencoder, VAE, GAN, RNN, LSTM, GRU, LLM, LMM, LAM, Transformer, Diffusion models and etc.Backend: Nginx, RestAPI, SOAP, gRPC, GraphQL, WASM, Oauth2, JWT, .Net Core 1.0-3.1, .Net 5-8, Flask, Django, Fast API.Database: MSSQL, MySQL, PostgreSQL, MongoDB, ClickHouse, Redis, Memcached, Cassandra and etc.Bla-bla-bla: GoF, SOLID, DRY, KISS, GRASP, YAGNI.Any other technologies and libraries:- Cmake, Makefile, GCC, GDB, Clang.- Numpy, Pandas, Sklearn, SQLAlchemy.- Tensorboard, Grafana, Prometheus, Graphite, ClearML, Swagger, AsyncAPI, Redoc.- CI, CD, GitLab CI, Docker, Kubernetes, Airflow, MLFlow, Elasticsearch, RabbitMQ, MassTransit, Kafka, Celery, Faust, Sentry.- Git, GitLab, Jira, Confluence, Trello, MS Project, MS Visio, Draw.io.- Agile, Scrum, Kanban, SAFe, SDLC, SSDLC, DDD, ETL, ELT, Event Driven, ArchiMate, BPMN, C4, UML, EPC, IDEF0, TOGAF, LEAF, Gartner-Meta, Sparx EA, Visual Paradigm, EDA, CQRS, Event Sourcing.
