AI/ML Engineer at EchonLabs who fine-tuned an F5-TTS model to create a Sinhala text-to-speech system.
What I'm looking for
At EchonLabs (Pvt) Ltd, I fine-tuned the F5-TTS Base model to develop a Sinhala text-to-speech system, and built a 3,000+ sample speech dataset through collection, transcription, validation, and preprocessing.
I also developed multi-agent communication systems and an AI-powered SQL Assistant. On the Multi-Agent Communication Platform project, I implemented LangGraph orchestration for a system handling 10,000+ daily interactions across multiple channels.
At OXZON AI, I designed and implemented RAG systems using vector databases and contributed to projects focused on NLP and LLMs. I’m eager to bring AI-native product experience to an AI-driven risk and compliance platform.
