Senior software engineer building production AI systems, owning features end-to-end with reliability, cost, and security.
What I'm looking for
I’m a Senior Software Engineer with 12+ years of experience designing and building production AI systems, including RAG pipelines, LLM-driven personalization, and agentic workflows. I own AI features end-to-end—from spec through deployment, observability, and on-call—bringing reliability, cost control, and measurable quality to e-commerce and enterprise environments.
I’m skilled in Python, Go, and system design, and I focus on accuracy, attention to detail, and documenting architectural decisions so teams can move independently. I’ve built high-throughput services and admin dashboards, integrated vector search (Pinecone) for knowledge retrieval, implemented RBAC/audit logging to meet SOC 2 needs, and mentored engineers through architecture and code reviews in fast-paced, entrepreneurial settings.
