Maksim

Contributed to the ydb-platform/ydb and ydb-platform/nbs repositories by developing nine features and resolving a critical bug over four months, focusing on scalable storage solutions and developer productivity. Delivered enhancements such as a local development environment, modular gRPC APIs for NBS 2.0, and observability improvements using C++, Python, and ProtoBuf. Introduced in-memory storage options, dynamic partition management, and a dedicated storage proxy service to improve latency and deployment agility. Prioritized code readability, maintainability, and robust testing, while addressing large-data handling by increasing unaligned request limits. Emphasized backend development, actor model programming, and cloud storage management throughout the work.

In May 2026, the team focused on stabilizing large-data handling in the NBS component by delivering a critical bug fix to support bigger unaligned requests and prevent related errors in the cloud blockstore path. The change increases the maximum unaligned request size to 128MB, enabling larger payloads, improving throughput for large data workflows, and reducing failure scenarios due to unaligned requests. This work enhances reliability for storage workloads and aligns with the goals of scalable data ingestion and processing while maintaining service availability.

In January 2026, delivered three strategic features for ydb-platform/ydb that enhance local development, storage management capabilities, and API modularity. Local Development Environment Setup provides scripts and configuration for starting YDB locally, including storage pool definitions, tenant creation, and root domain configuration, significantly accelerating local testing workflows. NBS 2.0 API and Data Operations via gRPC adds a robust gRPC surface for creating/deleting NBS partitions and performing read/write operations, expanding programmatic storage management. Public API Refactor and Naming Cleanup decouples the public API from core NBS components, standardizes request/response naming, and updates I/O message structures to improve modularity and maintainability. Collectively, these changes improve developer productivity, reduce integration risk, and position the platform for scalable storage operations across NBS 2.0.
