👨‍💻 Work experience

  • DL Researcher at SBER AI (April 2024 - Present day):

  • DL Researcher at AIRI (April 2023 - May 2024)
    As a result of the research we propose several new models for crystal structure generation and modification code

    • New materials design with VAEs (VAEs)
    • Formation Energy regression with neural networks (GNNs, PointNet, CNNs, Transformers)
    • Crystall structure generation, optimization (Diffusion, Flow Matching, Bridge Matching, Auto-Encoders, CNNs, Transformers, En-Transformers)

  • DL Engeneer at SBER Cyber Security (July 2022 - April 2024):

    • NLP: fraud call analisys
    • Classic ML: fraud detection with gradient boosting
    • Transaction Graph Neural Networks (GCN, GAT, GraphSAGE, Graphormer, GIN)
    • Transaction Graph Neural Network pretraining (self-supervised: ARGA, ARGVA, GAEs, VGAEs, Contrastive Learning)
    • Transaction Graph Neural Network (Temporal GNNs)
    • Transaction sequence scoring (LSTM, GRU, Transformer Encoder)
    • User scoring (Gradient Boosting, Ensembling)
    • Vulnerability detection in assembly with neural networks (Angr, GNNs)
    • Antifraud Voice Bot for preventinng call fraud (BERT, NSP, Pretraining, SFT, GPT, FAISS, HNSW, Retrieval, Whisper, ConFormer)
