About

I build high-throughput distributed systems that scale under pressure. As a Senior Software Engineer at Perfios, I architect backend infrastructure processing 30M+ daily requests — from fraud detection pipelines to serverless bank verification APIs. I specialize in Python/FastAPI microservices, async programming, and AWS-native cloud design. My work focuses on three things: performance (30% latency reduction via async refactoring), reliability (real-time observability with Kafka + ELK Stack), and scale (systems handling hundreds of thousands of daily requests on elastic infrastructure).
