# Antony Ranjith (0xAnto)

> Head of Engineering at Xyra Labs (formerly Kana Labs) since November 2025, Chennai, India. Four years of production systems that handle real money: led xyra.trade, a fully on-chain order-book perpetual futures exchange on Aptos with over $2 billion in lifetime volume; built the Kana Paymaster (over 370 million sponsored transactions) and Kana's cross-chain swap aggregator (over $1 billion in swap volume). Leading a high-performance trading engine in Rust. Focus: AI inference, model infrastructure, speech AI, and research engineering. Builds streaming speech recognition that runs on-device (OpenVox: ONNX, MLX, Apple silicon), speech-model pipelines and evals for detecting AI voices on live calls, and research code under a pre-registered evaluation protocol (CRUX). Also builds with LLM APIs (Claude, OpenAI, open-weight models through OpenRouter) and runs an AI-native engineering team. Full-stack engineer since 2022. B.Sc. Computer Science, Bharathidasan University (2019–2022).

## AI work

- AI-voice detection on live calls (private): real-time speech-model pipeline and evals for telling humans from AI agents
- [OpenVox](https://github.com/0xAnto/openvox): on-device dictation for macOS, a side project. Streaming speech recognition runs locally on Apple silicon (Moonshine Streaming, NVIDIA Nemotron Speech Streaming 0.6B; ONNX, MLX)
- [CRUX](https://github.com/0xAnto/crux): open research on a 17–30M-parameter decision model; four architectures under one pre-registered protocol; training not started yet
- [srch](https://github.com/0xAnto/srch): Rust search over Claude Code, Codex, and Cursor histories
- [mem0](https://github.com/0xAnto/Mem0): terminal memory for developers and AI agents
- [loom](https://github.com/0xAnto/loom): skill framework for coding agents

## On-chain systems

- [xyra.trade](https://xyra.trade): order-book perpetual futures exchange, fully on-chain on Aptos. Over $2B lifetime volume. Led the core protocol, trading infrastructure, and risk engine.
- [Kana Paymaster write-up](https://medium.com/xyra-labs/kana-paymaster-on-aptos-e414a37111d6): gas sponsorship on Aptos, 370M+ sponsored transactions
- Kana cross-chain swap aggregator: any-to-any swaps across EVM and non-EVM chains, over $1B swap volume
- ERC-4337 smart-wallet SDK supporting 14+ chains
- [move-integers](https://github.com/0xAnto/move-integers): signed integers for Move, 100% test coverage
