NetherlandsSenior Software Engineer at Funda
About
At Funda, I scaled and hardened an OpenSearch saved-search pipeline, cutting peak-import matching lag from 2 hours to 7 minutes. I also improved property-detail endpoint p95 latency from approximately 900 ms to 300 ms at peak load.
I piloted an LLM-assisted service that extracts structured highlights from property descriptions, with validation and human review for uncertain outputs. I also improved top-ranked listing CTR by approximately 12% through an A/B-tested ranking update.
At Mercell, I extended procurement rules, supplier scoring, and recommendations, and replaced synchronous report generation with background jobs and S3 storage. Earlier, at Ozon, I worked on warehouse systems, including a microservices migration of 70M+ records and CPU optimization for an inventory expiry system.
