Customizable virtual joystick offering touch-based directional controls with configurable dead zones, selectable 4- or 8-direction modes, reactive move events, and customizable visuals/background styles.

Replica la API oficial de Firebase, entrega módulos modulares, integración con coroutines/Flow, serialización tipada (value<T>, toObject<T>, set<T>) y testing con emulator.

Functional monads for safer null and error handling: Maybe, Either, Try; error-accumulating types, evaluation combinators for combining results, and tuple utilities up to quintuple.

Unified API for runtime permission management and device information, offering asynchronous, coroutine-friendly permission requests/status (single or batch), rationale handling, and location monitoring with live-tracking and state updates.

Lightweight signal abstraction for emitting typed events and connecting synchronous handlers. Includes connection handles and a global named-signal registry for simple, minimal event routing.

High-level API for discovering, connecting to and exchanging messages with Bluetooth mesh companion devices, featuring scanning with filters, reliable acknowledgements, auto-sync time, channel polling and message streams.

Async suspend-based streaming I/O layer exposing AsyncFileSystem/AsyncReadOnlyFileSystem, AsyncCloseable, async raw sources/sinks, buffered AsyncSource, AwaitPredicate, virtual/noop/system filesystems, random/discarding streams, portable implementations.

Enables real-time bidirectional communication with Phoenix Channels via WebSocket, channel join/leave, push messages, event routing, automatic exponential-backoff reconnection, heartbeat, and type-safe message handling.

Analytics client: non-blocking event queue, batching with retries and exponential backoff, local JSONL persistence for offline delivery, typed properties, session/device identity and lifecycle controls.

Type-safe test fixture generation with a composable, declarative API for building complex object graphs, nested overrides, sealed/enum/null handling, annotation-driven auto-registration, and testing-framework integration.

Sync and data stack for Quran apps: OIDC authentication, SQL-backed local persistence, orchestration of sync engine via DI, unified SyncService API, mutation/observe primitives and demos.

CommonMark-compliant Markdown parser and renderer offering AST access for inspection and manipulation, extensible with GFM-style extensions (tables, strikethrough, autolink), outputs HTML, Markdown, or plain text.

HTTP traffic inspector with overlay UI: captures full request/response details (headers, body, status, timing), searchable color-coded list, shake-to-open panel, zero runtime cost when disabled.

Lightweight wrapper around a file-IO implementation, fixing non-ASCII path handling, adding fluent path-building DSL, withFs execution block and Path-centric file operations (read/write/move/delete).

Per-object thread-local storage: ThreadLocal type supplies independent per-thread object copies; faithful line-by-line transliteration of upstream crate, port-lint provenance headers, feature-parity in-progress.

Unified toolkit offering app lifecycle, device and app info, clipboard read/write/observe, network and keyboard monitoring, haptics, sensor observation, navigation, share-sheet and file pick/save helpers.

Pure systems-programming toolkit enabling bit-exact C semantics with single-heap memory, C-compatible types, deterministic floating-point, and dual-mode bitshift engine for reliable C-to-language porting.

Fake-data generator for tests that builds realistic object graphs with scoped overrides, deterministic seeds, nested targeting, collection/map handling, null/default control, and extensible add-ons.

Reusable patterned backgrounds and follow-glow visuals for Compose, with immutable styles, runtime states, rich layout and interaction presets, lightweight blur, parallax, and seeded randomness.

Type-safe LSP 3.17 message models and transport-agnostic LanguageServer/LanguageClient interfaces generated from metaModel.json; optional ksrpc JSON-RPC bindings, union-type mappings, lifecycle and progress helpers.

Transparent proxy converting non-stream OpenAI Responses and Chat Completions requests into SSE upstream streams, aggregating events in memory and returning single JSON responses, while passing through streaming requests unchanged.

Event-driven, non-blocking asynchronous runtime featuring multithreaded work-stealing scheduler, reactor, async TCP/UDP and runtime primitives; faithful line-by-line transliteration of upstream implementation with provenance headers.

Generate native splash screens from a single Gradle DSL, auto-producing per-density assets and launch assets; runtime API to preserve/remove splash until UI ready, with dark‑mode and per‑flavor wiring.

Collection of libraries offering lexicographically-sortable ULIDs, zero-overhead 64-bit BitSet with bitwise ops and set-bit iteration, and unified asynchronous file I/O including OPFS support.

Direct Compose Desktop rendering into toolkit-owned Wayland wl_surface via EGL, bypassing X11/JAWT; creates wl_egl_window, resizes buffers, supports integer buffer and fractional UI scaling.

Pure zero-runtime-dependency Zstandard codec producing standard zstd frames with dictionary support; immutable digested dictionaries reusable across threads, one-shot API, and decompression-bomb guard.

Enables easy execution of native functions in fission.io, offering a simple setup with dependency inclusion, function registration, and specialized environment deployment for seamless function routing.

Facilitates code sharing for backend and mobile projects related to cocktails. Includes DTOs for cocktail data, filtering capabilities, and serialization support using kotlinx.serialization.

Wraps SQLCipher from Cocoapods, enabling database encryption features for native iOS targets. Addresses module-related issues in certain plugin versions. Available via Maven Central.

RPC-serializable logging interfaces for forwarding and aggregating logs across services — local routing, streaming, filtered subscriptions, and batched delivery with deduplication and replayable storage.
