- Operate async task infrastructure processing ~5 billion tasks/day at a 99.9% SLO — ensuring durable, exactly-once execution under extreme QPS. - Shipped deduplication and debounce primitives that eliminated duplicate work across partner teams, reducing unnecessary system load and simplifying safe enqueue patterns. - Designed and launched a scheduler platform for delayed and long-running work (reminders, notifications) — replacing ad-hoc task handling with operationally safe, durable execution. - Owned the full OAuth + third-party integration lifecycle — auth flow design, token refresh, connection health monitoring, and link preview reliability — for Notion's external integrations. - Built a runtime configuration management system that ensures safe, reliable config delivery at service startup reducing misconfiguration-driven incidents during rollouts. - Led multi-cell infrastructure readiness, adapting services and IaC to support global, multi-region enterprise customers. - Drove incident response as infrastructure on-call, cutting MTTD and MTTR through better alerting, runbooks, and systematic post-incident improvements.

About

I build backend systems that don't flinch under pressure. At Notion, I bult async infrastructure that processes ~5 billion tasks every day — queues, schedulers, deduplication, and the primitives that make distributed work reliable at scale. Most of my work sits in the space where reliability meets platform engineering: designing systems that are correct by default, operationally safe, and easy for other engineers to build on. I've shipped scheduler platforms for reminders and notifications, owned OAuth and third-party integration lifecycles end-to-end, and driven incident response as infrastructure on-call. Before Notion, I owned org-wide authentication infrastructure at FireEye (sole owner, zero downtime) and built real-time chat and chatbot systems at SmatBot. What I care about: high ownership, systems that scale, and teams that move fast without breaking things. Currently open to: Software Engineer / Backend Engineer / Software Developer roles / Infrastructure roles.
