Serafim Tkachenko

Engineering Team Lead / Technical Lead transitioning deeper into Machine Learning Engineering and Research Engineering.

I have 10+ years of software engineering experience across investment banking, trading technology, backend platforms, applied R&D, and production-critical systems. My current focus is deep learning, LLM interpretability, representation learning, quantitative systems, and AI applications in finance and science.

Current focus

  • LLM interpretability and representation engineering
  • Sparse Autoencoders and activation-space analysis
  • Deep learning and research engineering
  • Geometric deep learning and scientific ML
  • Quantitative finance systems and trading analytics

Selected projects

Topology-Aware EGNN for HOMO-LUMO Gap Prediction

Research-style project on geometric deep learning for molecular property prediction.

The project combines:

  • E(n)-Equivariant Graph Neural Networks
  • topological data analysis
  • persistent homology features
  • FiLM conditioning
  • robustness evaluation under coordinate noise

Repository: qm9-egnn-tda

Background

  • Engineering Team Lead / Technical Lead in Electronic Equities Analytics IT
  • Production systems for trading analytics, pre-trade risk, trading data capture, permissioning, P&L and execution analytics
  • Earlier experience in computer vision and machine learning for industrial video-stream analysis
  • Deep learning coursework with projects in geometric deep learning and molecular property prediction

Technical stack

Python, PyTorch, NumPy, pandas, scikit-learn, Java, C++, KDB+, SQL/Oracle, distributed systems, backend engineering, ML experimentation, deep learning, graph neural networks, LLM interpretability.
