Hitesh Solanki
Software Engineer & Builder · Mumbai, India
I'm a full-stack engineer passionate about building meaningful products through clarity and strong execution. I currently work at Strique AI where I develop e-commerce dashboards with Java, Spring Boot, and Next.js.
Resonance is a personal project born from my interest in AI and voice technology. I built it end-to-end to explore what's possible when you combine modern language models with high-quality TTS synthesis — and to give creators a tool that just works.
