About Me
Hi, I’m Vsevolod Nedora. I work as a Quantitative Developer at FlexPower, where I build algorithms for energy trading and research. Most of my day-to-day work sits at the intersection of high-performance computing (C++) and data analysis (Python), with a current focus on forecasting electricity prices and making sense of the ever-changing energy landscape.
Before joining industry, I spent several years in astrophysics research at the Max Planck Institute for Gravitational Physics, studying neutron star mergers and gamma-ray bursts. Along the way, I developed open-source tools like PyBlastAfterglow for simulating afterglows, and bns-ppr-tools for relativistic hydrodynamics. Those projects taught me as much about software engineering as they did about physics.
These days my side projects often connect back to energy. For example, I maintain an MLOps pipeline for short-term electricity price forecasting, and I’ve been experimenting with NLP tools to summarize energy news. Both are ways for me to explore how data and automation can help navigate complex systems.
Outside of work, I enjoy travelling, photography, and writing science fiction. Teaching and mentoring have also been rewarding parts of my journey, and I’m always happy to share knowledge or collaborate on interesting ideas.
If any of this resonates, feel free to reach out—I’m always glad to connect.

Personal Projects
Energy Heartbeat
An automated, temporally-aware knowledge graph that transforms scattered European energy news into structured, queryable insights using NLP/LLMs. A daily pipeline scrapes and cleans 13+ sources (TSOs, regulators, markets, analysis), semantically chunks articles, and extracts time-stamped entities/relations to answer “as-of” and “what-changed” questions—starting with Germany.

MLOps Electricity Price Forecasting Project
Leverages MLOps pipelines for accurate week-ahead forecasts of renewable energy generation, electricity load, and prices. Combines robust data engineering, advanced ML models, and scalable automation to optimize operations, enhance trading strategies, and support sustainable energy integration.

Academic Software
PyBlastAfterglow: Electromagnetic Signature Modeling for Gamma-ray Bursts
PyBlastAfterglow is a C++ code with a Python interface designed to model light curves, spectra, and sky maps of gamma-ray bursts and kilonova afterglows. It numerically solves the hydrodynamics of shock fronts and the evolution of electron distributions, and computes synchrotron and SSC emission. The modular structure of the code makes it easy to incorporate new physical models or techniques.

Photography
Distilled Emotion
Through my work, I aim to distill the calming power of nature and capture it with a camera. Whether it's sunsets, cloudscapes, or close-up details of nature, I want my photos to evoke a sense of serenity and thoughtfulness.
Writing
Science Fiction
I think a lot about the future of humankind and how technology, culture, psychology, and science may evolve. I try to explore these ideas through stories that readers can enjoy. Most of my writing has been done in Russian and can be found on Samizdat. However, more recently, I’ve started writing in English, with some works available on Wattpad.
The Orchestrated Rain
- Marcus wakes up to find his family gone, leaving only a short note and a trail to the City. He sets off, determined to bring back his son and his future. Meanwhile, Elena arrives in the City, searching for a promise that feels out of reach, only to face an unexpected storm that changes everything.
