What I'm looking for

I seek roles building production-ready generative AI/NLP systems, emphasizing research-to-deployment, low-latency inference, and collaborative teams that value experimentation and scalable MLOps.

I am a machine learning engineer specializing in generative AI, NLP, and production-ready model deployment, with hands-on experience in text-to-speech, voice conversion, and virtual-try-on systems. I have driven end-to-end pipelines from research and fine-tuning (LoRA, QLoRA) to optimization and scalable deployment using tools like Triton, TensorRT, Docker, FastAPI, and AWS.

My work includes hybrid retrieval-classification systems, multi-persona chatbots, and accelerated diffusion model pipelines, plus publications and research contributions in low-resource speech processing and TTS/VC. I collaborate closely with cross-functional teams and ship robust, latency-optimized ML services to production.
