Summary
🤩
Rockstar🎓
Top SchoolAlexey Kondratov is a Lead Software Engineer based in Berlin with 12 years of experience building and architecting distributed databases and backend systems. He brought Neon’s serverless Postgres from concept to production-grade features—contributing to core components like zenith and pageserver and improving branching, error handling, and low-level database structures. Before Neon he worked on PostgreSQL core features at Postgres Professional (pg_rewind, ptrack, sharding and logical replication), and now continues to push further separation of compute and storage at Databricks. Trained as a theoretical physicist with a PhD in condensed matter, he blends rigorous analytical thinking and numerical simulation experience with hands-on systems engineering. He’s comfortable across languages and domains—from low-level DB internals and performance-critical Rust/C work to Python-driven research tooling—and has a track record of turning academic complexity into production software. An often-unexpected asset is his background in optics and signal processing, which informs a methodical approach to debugging, modeling, and designing robust systems.

Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
Role in this project:
Back-end Developer & Database Engineer
Back-end Developer & Database EngineerContributions:603 reviews, 60 commits, 175 PRs in 1 year 8 months
Contributions summary:Alexey primarily focused on back-end development tasks within the Neon serverless Postgres repository, specifically contributing to the `zenith` and `pageserver` components. Their contributions include refactoring error handling, implementing branching output functionalities, and enhancing the branches tree drawing routines. They also worked on database-related tasks by adding and modifying data structures like `RelTag` and `BufferTag`, and by updating and implementing various database functionalities like the create, rename, and deletion of databases and roles. These contributions indicate a strong focus on improving core database features and functionalities.
