What I'm looking for

I seek roles building scalable, production AI/ML and LLM platforms with strong engineering practices, observability, and collaborative, growth-oriented teams.

I am a Senior Software Engineer focused on building AI-driven, cloud-native platforms and full-stack LLM-powered products. I led the design and deployment of a production AI platform with multi-agent orchestration, RAG pipelines, and sub-second P95 latency, and have driven improvements in automation, observability, and system scalability.

My background spans production ML engineering, backend microservices, and frontend implementations using React, Python, and Java/Spring Boot. I establish engineering best practices, mentor engineers, and deliver robust CI/CD, monitoring, and safety guardrails to ensure reliable, high-impact AI solutions.
