At EveryMatrix, I designed and built Tracker, a click-tracking service serving ~1,200 rps, and PQS, a Kafka-based service processing ~700 messages/sec. I also built the Python LightGBM prediction service used by PQS and deployed services on Kubernetes.
At Docudots, I designed and developed six Go backend services for a fintech platform, integrated third-party payment providers, and tuned PostgreSQL reporting queries, cutting key query times by ~60%. Earlier, I led engineering teams at ITHire.com and Armenian National Agrarian University, and built backend and analytics systems with Go and PHP.
