Resumable tus protocol implementation offering a client, embeddable server library, standalone runnable server jar, shared protocol primitives, and end-to-end integration tests.

Lightweight coroutine-based countdown timer exposing StateFlow states (Idle, Running, Paused, Finished), periodic interval ticks, and controls for start, pause, resume, stop, and restart.

Dynamic UI engine rendering native Compose widgets from JavaScript at runtime via QuickJS+Rust bridge; 40+ components, candlestick charts, reactive state, WebSocket realtime, cross-screen persistent store.

Comprehensive device security toolkit: fingerprint-based stable IDs, root/jailbreak and emulator detection, app integrity checks, VPN/proxy inspection, remote-control/surveillance detection, modular detectors, aggregated risk scoring.

Encrypts and stores application data with simple save/load/delete API, alias-based key initialization, and coroutine-friendly async operations for secure persistent storage.

Chunked multipart uploads to cloud storage with pause/resume, retry and persistent upload state across restarts. Enqueued background engine, per-chunk progress stream, and pluggable HTTP callbacks.

Asynchronous HTTP client offering DSL-style request builders, configurable engines, interceptors, streaming responses, multipart support, and extensible plugins for concise, testable network code.

Detects runtime environment as an enum, exposes currentPlatform constant, offers lightweight, easy-to-integrate API and extensible hooks for telemetry-friendly platform metadata.

Safe-area and window-inset utilities for Compose, offering rememberWindowInsetsController, WindowInsetsController APIs, a WindowInsets UIViewController wrapper, navigation/status bar padding modifiers, and runtime visibility control.

Serialises data structures with robust reference and cyclic-graph handling, JSON-friendly output, pluggable strategies for object identity, and straightforward integration into serialization pipelines.

Safe-area utilities calculating display insets, applying edge paddings/margins, and dispatching window insets for consistent UI layout across varying device display cutouts and system bars.

Collection of extension functions and small utilities improving API ergonomics, DSL creation, common conversions, testing helpers and interop conveniences for library development.

Unified networking fabric with session API, swappable transports, replicated CRDT data structures, Raft consensus and leadership, turn-based game and fair-deal utilities, conformance tests.

Client for interacting with app API: request/response handling with JSON, file and form inputs, collection-format queries (csv/tsv/ssv/pipes), numerous domain models (payments, chat, AI) and bearer auth.

Elegant, type‑safe, locale‑aware date/time, interval, relative‑time, duration and period formatting via readable DSLs; smart interval merging, customizable formats, and implicit locale/timezone scoping.

Firebase-first SDK exposing coroutine-style suspending functions, reactive flows, and serialization-backed read/write for Firestore, Realtime Database, Auth, Functions, Storage, Messaging, Installations.

Shared libraries published to Maven Central; modules versioned and released independently via tag-driven publish workflow that publishes only the tagged module; consumers need only mavenCentral.

Client for loops.so API with full endpoint coverage, typed resource groups, direct vs proxy modes to prevent shipping API keys, automatic 429 retries, configurable timeouts and logging.

Versioned shared backbone for apps: published libraries (MVI runtime, design system, image), unified build and style tooling, and Claude Code AI assets that teach assistants to adopt and use conventions.

Utility extensions for common types, coroutine-safe runCatching, flow helpers (single‑consumption, saved‑state and preference‑backed StateFlows), lifecycle stream, MD5/hex, semantic versioning, image/string helpers.

Line-by-line transliteration of RustCrypto/hashes, offering API parity across many cryptographic hash algorithms (SHA‑1, BLAKE2, MD5, …); includes source provenance headers.

Port of the ANTLR v4 runtime translating Java sources into a portable implementation, enabling ANTLR-generated parsers; runtime API parity work ongoing.

State-of-the-art starter pack organizing code with Clean Architecture and DDD: layered Domain/Data/Presentation, use-case invoke patterns, self-validating models, Koin DI, optimized CI/CD.

BER‑TLV/TLV parser for EMV payment data: recursive decode of constructed/primitive tags, hex-string I/O, comprehensive EMV tag dictionary, and rich value explainers and visualizations.

HTTP-capture debug toolkit: Ktor interceptor, bounded event bus with ring-buffer, header redaction, in-app overlay (shake to open), and zero-install live web viewer streaming events.

Automatic generation of type-safe navigation routes, serializers, per-screen Actions, wrappers and screen mappers from annotated Composable screens, eliminating manual polymorphic serialization and navigation boilerplate.

Multifaceted AI tooling library delivering typed agent and tool contracts, streaming text and structured outputs, provider/gateway adapters, embeddings and media primitives, telemetry, mocks, and utilities.

Lightweight typed ID generation and parsing with compact formats, validation, deterministic creation, and easy serialization for strongly-typed identifiers across application domains.
