What I'm looking for

I’m looking for a senior role to ship reliable GenAI/ML systems—LLM apps with RAG, evaluation, and guardrails—on cloud platforms, collaborating closely with product and research teams.

I’m a Senior AI/ML & software engineer with 10+ years of experience designing, developing, and deploying scalable artificial intelligence systems and cloud-native software solutions. I build enterprise GenAI applications—LLM-powered assistants, agentic workflows, RAG systems, vector search platforms, and production AI infrastructure.

I’ve led the architecture and delivery of production-grade LLM applications using Python and modern frameworks like LangChain and LlamaIndex, integrating vector databases and designing end-to-end retrieval pipelines. At BairesDev, Lilt, and Google, I’ve focused on LLM evaluation, inference optimization, observability, and responsible AI practices including AI guardrails and validation systems.

I enjoy partnering with research scientists, engineers, and product teams to turn emerging AI capabilities into reliable systems—backed by strong MLOps automation for model deployment, monitoring, versioning, experimentation, and lifecycle management. I also bring full-stack and backend engineering experience, building microservices, REST APIs, event-driven systems, and developer tools that improve scalability and delivery speed.
