Lightweight functional extensions for nullable handling, suspend-friendly mapping, type-safe casting, null-aware matching, and lift combinators for combining nullable values with concise chaining.

Extension utilities for reactive Flow streams: concise operators, converters, lifecycle-aware collectors, enhanced error handling, caching and testing helpers to simplify stream composition, transformation and consumption.

Streaming JSON parser emitting flat token events for incremental, chunked input; supports suspending reads, building or skipping value trees, and efficient selective field extraction.

Terminal manipulation toolkit: cursor control, rich color/styling (16/256/RGB) and attributes, screen/raw-mode management, event polling (keyboard, mouse, resize), command-pattern ANSI batching.

Audio recording engine with configurable sample rate, channels, encoding and output formats, reactive state (amplitude/duration), waveform-ready visual components, optional UI and lifecycle-safe controls.

Abstracts external services into swappable implementations (databases, caches, files, email/SMS/push/pubsub), with built-in metrics, health checks, local-run helpers and Terraform generation.

High-performance LaTeX math parser and renderer with incremental parsing, automatic line breaking, image export, MathML conversion, accessibility (MathSpeak), formula highlighting, animations and WYSIWYG editing.

BSON-first MongoDB client with ergonomic typed serialization and DSL builders for filters/updates; supports CRUD, sessions, transactions, SRV/TLS, index helpers, and a raw BSON escape hatch.

Client for YAXI Open Banking services handling interactive consent flows, dialogs and redirects; returns JWT-authenticated results, session/connection reuse, async CompletableFuture facade and refresh support.

Physics-based cycling simulator converting static GPX traces into virtual rides with realistic speeds, times and power estimates; elevation correction via Terrarium DEM, smoothing, resampling and GPX output.
