Kubernetes Event-Driven Autoscaling — extends Kubernetes' built-in HPA (Horizontal Pod Autoscaler) with 60+ scalers for external event sources. Where standard HPA scales on CPU/memory, KEDA scales based on external metrics: Kafka consumer lag, Azure Service Bus queue depth, AWS SQS messages, Prometheus metrics, Cron schedules, and many more. Enables scale-to-zero for event-driven workloads, activating pods only when messages are waiting. CNCF graduated project.

Database schema change management tool supporting SQL, XML, YAML, and JSON changeset formats. Liquibase tracks changes in a changelog file with individual changesets, supports rollbacks via inverse change generation, and provides diff capabilities between databases. More feature-rich than Flyway with better rollback support, multi-database abstraction, and programmatic Java changelog capabilities.

Command-line runner for Postman collections. Newman executes Postman API test collections in CI/CD pipelines, terminal, or scripts — without requiring the Postman GUI. Supports running collection runs, generating JUnit XML reports, and chaining requests. Used to automate Postman-based agent API test suites in CI/CD workflows.

Python memory profiling and object analysis toolkit — measures object sizes, tracks memory over time, and identifies memory leaks. Pympler features: asizeof() for object memory size, muppy for heap tracking and diff, summary.print_() for object type summary, tracker.SummaryTracker for incremental tracking, refbrowser for reference browser, classtracker.ClassTracker for class instance tracking, web interface for browser-based memory analysis, and flat_diff() for memory change detection. More accurate than sys.getsizeof() — includes referenced objects.

Serverless vector database by Upstash with per-request pricing. Stores and queries high-dimensional vector embeddings for similarity search, RAG (retrieval-augmented generation), and semantic search use cases. Designed for edge and serverless deployments with HTTP API.

Lightweight private npm registry server. Verdaccio enables publishing and serving private npm packages within an organization without paying for npm Pro/Enterprise or Artifactory. Also acts as a transparent proxy/cache for public npm packages, reducing CI/CD build times by caching commonly used packages. Simple setup (single Docker container) makes it the go-to solution for teams needing a private npm registry without heavy infrastructure.

Asynchronous HTTP client and server framework for Python asyncio. Provides both an async HTTP client (aiohttp.ClientSession) for making concurrent HTTP requests and an async web server for building APIs. Supports WebSockets (both client and server), streaming, middleware, and connection pooling. Predates FastAPI — used by applications needing both client and server HTTP in one library.

A universal MCP server that transforms any GraphQL or REST API into a natural language query interface, with DuckDB-based SQL post-processing for operations the target API does not natively support. Learns from successful queries via cached recipes.
