What I'm looking for

I seek roles where I can lead GenAI/LLM engineering and scalable ML systems, work cross-functionally, and ship production products in cloud-native environments while driving measurable business impact.

I am a Senior Software Engineer focused on Generative AI, LLM engineering, machine learning, and full-stack development, with extensive experience building scalable, production-grade systems across fintech, insurance, and healthcare. I design and deploy end-to-end GenAI pipelines, fine-tune transformer models, implement evaluation frameworks, and optimize inference for low-latency, high-accuracy NLP solutions.

I have led multi-cloud, containerized deployments and infrastructure-as-code practices, reduced release cycles and hallucinations through advanced prompt engineering and guardrails, and delivered measurable business impact via RAG, retrieval, and analytics platforms. I thrive in both startup and enterprise settings, translating complex technical problems into robust products that improve operations and user experiences.
