February 2026 — mlflow/mlflow: Delivered Backblaze B2 artifact storage support, expanding MLflow's artifact backend options and enabling storage and management of artifacts in Backblaze B2 Cloud Storage. The feature introduces the b2:// artifact repository, enhancing data durability, reducing vendor lock-in, and supporting multi-cloud workflows. Overall impact includes broader storage flexibility for ML artifacts, improved artifact management experience, and readiness for additional cloud-provider integrations. Technologies and skills demonstrated include cloud storage integration, artifact storage backends, and commit-based traceability in an open-source project.

CVAT — 2025-11: Delivered documentation to enable Backblaze B2 as an S3-compatible storage option, expanding CVAT’s cloud storage choices and enabling cost-effective multi-cloud storage for annotation data. The work focused on documentation and readiness for future backend integrations. No major bugs fixed this month; primary effort centered on storage options and user onboarding guidance. Impact: provides users with cheaper, flexible storage options (Backblaze B2 cited as up to 5x cheaper than traditional options) and high-throughput potential with B2 Overdrive (1 TB throughput and free egress), improving total cost of ownership and data accessibility. Technologies/skills demonstrated: technical writing, cloud storage concepts, S3-compatible APIs, CVAT documentation standards, and cross-team collaboration.
