At Cloudflare, I reduced infrastructure resource usage by 90% and delivered full fault tolerance and DDoS-resilient architecture for a business-critical service.

At Revolut, I built a company-wide ATS platform and introduced ML interview analytics. I implemented the Outbox pattern to eliminate Kafka message loss and cut database load by 30%.
