I'm Sonu, a full-stack developer from India — backend, frontend, and UI/UX — with a particular love for building offline-first, on-device AI apps. No cloud dependency, no tracking, just software that respects the user.

• 🧠 Passionate about local AI: agentic AI, text/LLM-based AI, TTS, and on-device AI in general — not tied to one type
• 🛠️ Working across Kotlin, Java, JavaScript, backend & frontend development, and ONNX-based on-device inference
• 📦 Both apps below are live, in production, and actively maintained
