Owned production ML platform & serving components spanning data access, workflow orchestration, and LLM/prompt enablement; partnered with product teams to ship governed ML/LLM use cases. Improved online serving reliability and performance through caching, rollout safeguards, and failure-handling patterns (SLO/alerting/oncall readiness). Built compliance-friendly capabilities (policy/RBAC hooks, auditability, data-retention/TTL-aligned deletion) to meet internal governance requirements. Drove internal adoption at scale via self-service tooling (SDK/CLI), onboarding docs, and cross-team design reviews, reducing typical onboarding from days to minutes.

Delivered production ML systems across end-to-end lifecycle (data/ETL → training → batch/online serving → monitoring), supporting core valuation products at national scale. Led platformization work to make large-scale ML pipelines more repeatable and operator-friendly (containerized workflows, orchestration patterns, standardized tooling). Built/raised the bar for observability and operational readiness for online model serving (dashboards, alerting, incident triage workflows), improving reliability and reducing time-to-detect/resolve. Partnered with data scientists, infra, and multiple product teams to ship model and system upgrades with safer rollouts and measurable quality gains. Mentored engineers/interns and served as a cross-team technical point for ML productionization decisions and delivery.
