What I'm looking for

I’m looking to build AI-driven products end-to-end—shipping reliable RAG/LLM workflows with measurable evaluation, scalable cloud services, and a strong product mindset.

I’m a Senior Software Engineer with 7+ years building production-grade full-stack and AI-powered systems across IoT, cloud infrastructure, and enterprise SaaS. Over the past 3 years, I’ve leaned hard into applied AI engineering—shipping RAG pipelines, agentic workflows, and LLM-driven automation with strong evaluation and guardrails.

At Samsara, I led the design and implementation of AI-powered features in the intelligence platform. I architected and deployed a Retrieval-Augmented Generation (RAG) pipeline powering an AI assistant for natural-language queries over fleet telemetry, safety incidents, and maintenance records. I also built agentic AI workflows using LangGraph/LangChain to triage IoT alerts, correlate anomalies, and generate contextual action recommendations.

At Amazon, I contributed to the Bedrock team and supported the GA launch of a fully managed generative AI service. I implemented serverless ingestion pipelines that chunk and embed documents for Knowledge Base indexing, and I helped enhance retrieval and prompt augmentation with hybrid search strategies. I also built internal evaluation harnesses for retrieval precision, answer faithfulness, and context relevance—integrated into CI/CD for continuous quality monitoring.

Earlier in my career, I built and evolved full-stack pricing and platform services, including REST microservices, React/TypeScript dashboards, streaming data pipelines, and CI/CD deployment automation. My engineering style is pragmatic and product-focused: I aim for systems that are reliable in production, measurable in performance, and maintainable as teams and models evolve.
