## Headline

Software Engineer at Bild\.

## 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\.
