I'm currently building DMP and advertising-platform services at WILDBERRIES, processing user profiles and behavioral segments at 25K RPS with p99.9 latency of 21 ms. I design profile-storage architecture, identity resolution, segmentation delivery, and reliable Kafka-driven processing for a platform with 270M user profiles.

I implemented identity resolution covering 160M profiles, including consent, opt-out, and shared-device handling across Web and Mobile SDKs. I also reduced Kafka consumer memory usage by 76%, from 2.1 GB to 500 MB, and introduced KEDA autoscaling based on consumer lag.

Previously at SUPO, I built NetSuite ERP integrations and reconciliation workflows for invoices, bills, payments, and transactions. I improved a heavy report from 20 seconds to 7 seconds through PostgreSQL indexing and query-plan optimization, while protecting financial consistency with transactions, idempotency, retries, and audit-ready observability.

At NETGURU, I delivered financial data pipelines handling more than 1M records per day, high-volume CSV imports, and third-party logistics and fintech integrations. I also built Kizuna, a self-hosted PostgreSQL, Redis, and Kafka data explorer packaged as a single Go binary with an embedded React interface.
