Summary
🤩
Rockstar🎓
Top SchoolKlim Kolyvanov is a PhD candidate and seasoned data scientist with a decade of experience applying machine learning, computer vision and backend engineering to scientific and blockchain domains. Based in Berlin, he developed scalable deep-learning pipelines for 3D+time microscopy (including sub-pixel object detection and parallelised Java tooling) while also contributing backend SQL, CI and smart-contract tooling to high-profile crypto projects like Yearn and Dune Analytics. His background blends strong numerical foundations (top grades in applied math and simulation sciences) with hands-on systems work—from FEniCS finite-element automation to Solidity linting and CI improvements—demonstrating an unusual cross-over between academic image-analysis research and production-grade data engineering. He’s comfortable shipping end-to-end solutions, localizing UIs, and optimizing developer workflows, and often surfaces pragmatic engineering fixes that improve reproducibility and maintainability across projects.

SQL views for Dune
Role in this project:Back-end Developer & Database Engineer
Back-end Developer & Database EngineerContributions:86 reviews, 33 commits, 139 PRs in 1 year 7 months
Contributions summary:Klim primarily contributed to the creation and modification of SQL views for the Dune Analytics platform, specifically focusing on the Erasure protocol and Bancor network. Their work involved writing SQL queries to extract and transform data from various smart contract events, and adding new tokens to the tokens and stablecoins tables. They also worked on incorporating code from different versions and sources, including the addition of new data.
